      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

'01 Pontiac Montana revs high

Recommended Posts

Sergeant Slabber

Ocassionally while in park or driving along, our Montana minivan will increase about 1,000 rpms. It stays that way for awhile and then will idle back down. It will just go back and forth like that. Just wondering what might be the cause of this fluctuation? Thanks for the help!

That's a tough one to field. Could be a vacuum leak, a bad idle air control motor, a coolant temp sensor with an intermittent problem, a weak injector.....That one will require a scan tool and some drive time. confused.gif

3.1 or 3.4 liter? How many miles on it? Does it see a lot of short trips? Does it get onto the freeway frequently? Do you ever notice the RPM's drop pretty low right before they go up? does it do it when its cold, when its hot, or anytime just out of the blue? Does it do it more or less with the a/c - defrost on? Do you ever notice a sticky gas pedal when you initially step on it?

airjer~ I believe it's the 3.4 with around 78,000 in it. It does see alot of 10-20 mile trips per week. The wife says she notices that it runs high when she first starts it, around 2,000 rpms. Normally it would be about 1,100 when first started. It doesn't drop any rpms before it shoots up. As far as a pattern, it seems to just increase those rpms out of the blue. She hasn't noticed the pedal being sticky either. In the spring we had the intake manifold gasket replaced, and early summer we had the A/C condenser replaced. It ran fine after those jobs, but maybe that has something to do with it now? I just added a can of Seafoam to the tank this morning to see if that will help with anything. Any thoughts? Thanks!!

HMMMMMMM! Without seeing it I would hate to even speculate at what it could be. The first thought might be a vacuum leak. Possibly the injector o-rings. I have started to replace these when I do the intake gaskets because I have seen several leak after the job is complete. Also look closely at the plastic/rubber vacuum hoses that go to/from the top of the throttle body. Especially the elbow that goes to the PCV valve, I have seen many of these rotted cracked and leaking!!

Hope that helps.

What if he sprays some carb spray around under the hood in certain areas while the engines running to see if the r.p.m.s climb up. Does anybody still try that old trick anymore? grin.gif

Yeaahh, NO! Hears a funny story. I had a Dodge van with a funky drivability problem. I had the doghouse off, was sitting in the drivers seat (by the way the drivers door didn't open) and was spraying carb spray to see if I could find a vacuum leak. So I finally figure out that the EGR diaghram is leaking by this time the engine is at full operating temp. I gave the EGR one more shot to confirm and WOOF!!! The whole thing caught on fire. I'm Stuck in the drivers seat the engines on fire and I have no where to go. I'm yelling for help and finally get the fire out after I burnt my arm and singed some hair on my head.

We know require that the drivers door be functional for any test drive or driveability diagnostics and the shop now has a pretty nice smoker which I have grown fond of!!!!

So, yes it can be done. People do it all the time. I don't recommend it. Please be extremely carefull if you do!!

Thanks for your input guys. I'll look around and see if I can find anything loose, especially that darn PCV which I know can rot or not be seated tightly. I know that sometimes when your driving along around 30mph and you can tell she's running a little high, you can take your foot off the gas and it will hold steady at 30-35 mph for awhile before it idles back down. Nice cruise control!

Airjer~ I noticed after driving the van a couple days ago that it definetly seems to run at higher RPM's when the heater is going. When I shut it off I see that it drops about 2-300. Any ideas?

Anytime the A/c is on the engine Idle will bump up. Usually it will only do it right before the compressor kicks in then idle down after it kicks out.

Thanks! I'll just keep an eye on it for now. At least I was able to put on new rotors and pads before this awesome, ice-making frigid air moved in smile.gif

      Hey I am planning on ice fishing on Lake Minnetonka this winter with a friend and I am using a snowmobile to get to the lake from the trails. I would enter onto the lake in Orono off the Luce line trail and end up in Stubbs bay. I was reading on other forums saying avoid the channels but it seems to be the only way to get around the lake to other bays especially since I am on a snowmobile. I was wondering if they eventually are safe enough to hold up a snowmobile in mid-late January, and if going through them faster helps possibly? I would like to fish around the Smith's bay area and the only way I can do that is going through channels. I know Lake Minnetonka can be sketchy with ice thickness and I don't want to end up through the ice, thoughts? Thanks.   Jim

      The DSL service is great since they ran the fiber down 24 a few years ago.   I was presuming that the poster didn't have that option if they were considering satellite.     AccessMN is another possibility if they are still around.

      OK I will post a report just on the offhand chance that someone else still reads these things.  Fished at Birchdale afternoon of Saturday 10/21 and morning of 10/22.  Fishing was good Saturday for keeper sized fish, nothing big but caught 29 fish in 6 hours,  mostly nice keepers 14 to 19 inches long and not too many dinks.  Sunday morning fishing was slow and then it got super windy so pulled the plug early and went home.  Jigging in shallower spots, could not troll crankbait because of debris on line.  Others had mixed success.  Shiners were around.

      10/22/17     Hunted water in central MN from a boat blind both days. Despite gusty south winds one day and temps not exactly October-like, new ducks were around that moved in during a cold, clear night with a west wind during the week. Calendar migrators from the Dakotas and southern Canada. Saw eleven species and harvested ten--typical late October mixed bag. A mixed, medium-sized decoy spread with a crosswind on a point with the sun behind us was the ticket. An Avery Quick Set blind with fast grass mats and two Lucky Duck HD spinners rounded out the set-up. Subtle mallard quacks, chuckles, and drake whistles mixed with goose clucks, pintail and wigeon whistles locked up birds nice and close--no loud contest calling. Cold weather and West and NW winds this week should get a bunch of new birds in--probably a mixed bag of species still. We saw or heard eight flocks of specklebellies migrating on Sunday. Look for a show about one of these days of hunting on my You Tube channel (Fishing and Hunting the North Country) by later in the week.  Good luck, and I will see you out there somewhere.

      I pulled my boat for the winter today. Sure hated to have to do that, but have tons of stuff to do to get ready for the fall, winter stuff! Cliff

      Good day!  Keep the reports coming! We’re islanders and had to pull out a week ago. On my last day out by myself I boated a thick 28” walleye to close my season. We brought filets Home so my old fisherman, 95 year old dad could enjoy a good fry,  I still enjoy reading about the lake so keep reporting. Thanks, Dick

      The wife and I were up to L O W  for whole week. Great weather, good fishing and fun time. Was able to fish 7 days split up between Morris point, Long point and the river. For me Long point was the better bite. May have seen a couple members of outdoors Mn on Tuesday out of LP. Let me know if I'm right. Also met member from Wisc. at Morris point( real good guy) Anyway didn't seem to matter much what color jig caught them on every color with frozen shiner. Some days were better then others but always caught fish. Ate several meals of fish and brought fish home. Also caught a 14 in perch that I brought into taxidermist. Plan on going back at least one more time this fall . ( Too good not to).
