hahah..and that is what originally happened with my check engine light,,i went to change mine myself..did it in the parking lot..there were 2 they said would work..i bought one and put it on and it began sucking air like you wouldn't believe..went inside and bought the other one and it was fine..but the check engine light came on..been on ever since. not sure how they figured out the egr valve but it worked..i have gone through so much sh*t with that van..2 intake manifold gaskets..one costing me an engine...and the list goes on

Replying to: chewson (Feb 04, 2008 1:39 pm) Usually when the EGR valve goes bad you'll stall when you lift the throttle, thats why it wasn't on my list of things to check, I'll have to make sure I remember that for when mine goes bad since all of these seem to break the same way - glad you're running good again. Thanks for the info!

i should be the one thanking you...helps when someone gives information when you get desperate. you are right about the egr valve which is probably why they never checked that first..that and what is wrong with the computer in the van that showed no code..even when the egr was disconnected...not much chance i'm ever buying another none of these Replies to this message: 442dude (Feb 05, 2008 2:56 pm)

#34 of 80 starts and runs like it is running on 2 cylinders by fughunter Feb 06, 2008 (10:54 am)
I have had a problem with this van ever since it turned 180,000 miles no that i have all the bugs worked out of it It throws something else at me now i have a obd2 code reader and it says (random cylinder misfier ) I changed the wires plugs still runs like poop . need a little help . i know alot about cars trucks and now this van but ths time i am wondering if it is timing chain or coils Replies to this message: 442dude (Feb 06, 2008 11:24 am) fughunter (Feb 07, 2008 3:12 am)

Replying to: fughunter (Feb 06, 2008 10:54 am) Couple of suggestions -   I had the misfire code as well - got rid of it by:   1. Cleaning the MAF sensor - use cleaner designed specifically for the MAF and follow the directions on the can   2. Replace the PCV valve   Also, try this - get a digital multimeter, check the resistance on the ignition modules (located in back on top) between the two towers on each (towers meaning where the spark plug wires connect to) the resistance should be 5000-7000 ohms - if its above or below, you've got a bad ignition coil...and make sure the posts are clean.   Someone else here also had an issue with the EGR valve being plugged up with carbon - you might want to pop it off and take a look...the pintle in the middle should move freely up and down (its spring loaded IIRC) - if not, try cleaning it and reinstalling, carb cleaner works pretty good, also know people who use Marvel Mystery oil to break up the carbon to make it easier to clean.   You've already done the other stuff I would suggest. Good luck Replies to this message: fughunter (Feb 07, 2008 3:12 am)

#37 of 80 oil pump by fughunter Feb 08, 2008 (2:58 pm)
you know after the other day i had a misfire i think i know what it really is now somehow my girlfriend didnt tell me the oil light came on now i have it figured out i do beleve the oil pump is gone out because it has oil and the lifters rattel have not run it to long you think it is hurt ? having a good time with this (CHEVY) i am a sole chevy man but man this van is driving me crazy. P.S do you think that it would sound also like it is missing if the oil pump is bad i know the answer is yes but i just wanted someone else to say so
#38 of 80 Engine turns over but won't start by gapcar Mar 17, 2008 (5:05 pm)
My 2000 Venture with about 111,000 miles has an intermitent starting problem.. It always starts fine when cold, but 3 times in the last 6 weeks it has failed to start when hot. So far the Firestone store said they "thought it might be" the crank position sensor. The water pump had leaked coolant on it so they figured that was the problem. I had them replace the water pump but not the sensor since neither the engine codes nor any other hard data supported the $250 cost. The second time it was towed to a Chev dealer who said the fuel pump was bad. They replaced the pump and fuel filter. I paid $1100 bucks that time and had 3 weeks trouble free driving before it died again. It has been towed to a local Chev dealer (different one than last time) and I am awaiting their diagnosis. This car has cost me over $4000 in the last 12 months! To make matters worse I have been reading about engine bearing problems! Any suggestions?

Replying to: gapcar (Mar 17, 2008 5:05 pm) Sounds like a crank position sensor failure - when they're on the way out they like to not work when they're hot - remember that they tell the injectors when to fire so if they aren't working the injectors don't fire..IIRC there are 2 of them on the Venture...once installed they have a learning procedure so you can't just swap & go...also, they don't always throw codes when they go bad so Firestone might just be right...good luck Replies to this message: towheelie (Oct 06, 2009 2:38 pm)
