Our 2002 van had a similar problem..code given said there was a missfire...took to dealership...said they solved the problem....pulled out of the parking SPACE check engine light came on again....took them two weeks to figure it was a loose wire that was causing the missfire..can you imagine that. Just throwing an idea...can never hurt to check the wires. hope this works
#31 of 34 2002 Chevy Venture Whirring noise and issues
Apr 05, 2010 (6:36 pm)
My Venture has been running fine since we got the transmission replaced last year, but there was a strange rattling sound when stopped at lights with a/c on... but it's been cold, no a/c, no issue. A couple of weeks ago we were on the highway and about 10 minutes into the trip, there was a whirring sound coming from the engine compartment, but as soon as I let my foot off the gas, the sound would stop, and it did not exist at slow or around town speeds. It would only start about 10 minutes into the trip at highway speeds and continued while on the highway. I took the belt off to see if any pulley was making noise and the tensioner was sloppy, making some noises, so I replaced it. I thought that was it, it's been running fine. That was a week or so ago. Easter Sunday I'm taking the family on a 400 mile trip and 10 minutes into the highway portion, the whirring noise starts again, same thing, when I take my foot off the gas, it stops, when I push the gas or use the cruise control, the noise starts again. I got off the highway and it stopped. I pulled into a parking lot and popped the hood, as I gave it gas, the engine started to go up and down like i was taking my foot off and on the gas, but I wasn't I was applying constant pressure. We let it idle for a minute and gave it gas again, and it was ok. We turned around and came home, the whole time on the highway we had the whirring noise, when we got off the highway and drove home, it was fine I did baby it a bit on the highway but it did get us there with no issues other than the noise. I don't even know where to start... Any suggestions? We drove the car, but when I get home on Wednesday, I'm going to have to dive into this problem... Please help.

I have a 2000 chevy venture that developed a similar problem with a whirring noise (around 85,000 miles) which also completely abated when the gas pedel was released. At first, the problem would also go away if I down shifted into 3rd gear, and would again return when manually or automatically shifted back into OD. Tried all kinds of tranmission additives which helped minimally. After about 8,000 more miles, the whining got worse, even persisting when down-shifted to 3rd gear, and I noticed my OD wasn't really working at all. Wound up having to have a full transmission overhaul.....the problem was a weakly contstructed factory overdrive gear. Replaced with a stronger, aftermarket product and now my transmission works perfectly with no whining.
I also recently replaced my a/c compressor and have begun noticing the same type of rattling sound when stopped in gear with the a/c on. Haven't diagnosed the problem yet as the a/c works fine and the noise resolves at driving speed. However, I tend to doubt that this a/c problem is related to your whirring noise (can't completely exclude that your the a/c compressior bearing isn't going out.) Perhaps of note, the belt-tensioning pully on my Venture started whirring recently (at 170,000 miles), and suddenly my serpentine belt broke, shutting off my power steering, a/c, alternator, and water pump......turned off engine immediately to prevent overheating. On replacing the belt, I noticed that the tensioner pully had actually frozen up and melted, ruining my old serpentine belt. Easily replaced the belt-tensioner ($50) and the serpentine belt, and problem solved. Ventures are great vans, but they require a lot of tinkering.

Thanks for the suggestions. I had the transmission replaced last year, it completely went... I don't remember the name, but I saw the part... sheared down to nothing. I don't know that the a/c is the problem or just the drain on the engine. I've not got a squeal coming from maybe the back end. I've also got an occasional clicking or knocking come from the engine area. It does not always do it, sometimes it stops, I've been able to pop the hood and look under, but can't determine what the cause is or exactly where it's coming from. When I take it to the mechanic, it's not doing any of those things. I don't always mind tinkering, I just wish I could figure out what to tinker with. Thanks again!

Floor board pass side under the carpet is a wire harness. it might be in the harness or the connector into the BCM. I have the same problem. found when I push my foot on the carpet it comes back on or I can make it go off
