Chevrolet - Venture :: 2000 3.1L - Surges On Acceleration
Sep 13, 2014
This car has 210k miles with very minimal problems. I'm the original owner and have always done my own repair work. For the last two years the car has been surging on acceleration. It is fairly rapid surging and it is intermittent. When it is especially bad I can let up on the throttle, press again and it may be OK...until the next time I accelerate. I have replaced a lot of parts, there are no trouble codes and nothing noticed in the data streams. I've tried four throttle position sensors (second one failed and set a code) and nothing makes any difference.
Here is a list of other parts I've replaced since this problem started, again nothing changes the surging, fuel pump (failed level sensor), fuel pressure regulator (pressure was on low side of range), idle air motor, map sensor, mass air flow sensor (swapped with my S10 pickup). I'm planning to donate the car to an organization after I get this problem fixed (my wife won't let me donate it with the surging problem since it could be safety issue if the car doesn't accelerate when its needed).

My Venture LS is stumbling upon acceleration. It starts to occur around 35 mph and then continues with occasional smooth sailing. No rough idle and no stumble when coasting. I had the spark plugs and wires replaced at the dealer today and it did nothing. Fuel trim is fine, LT runs from 0 to - 5 . I replaced the MAF sensor a few months ago and all other sensors test OK on the scanner.
Also, I took my car to the dealership to have the plugs and wires replaced and they used the after market wires named Xact. I have never been to a dealer where they used aftermarket parts. I thought that they were required by GM to use their parts?

OEM plus. 93k. Um tune. Evoms intake.
Did the plugs and coil packs, fuel filter, cleaned throttle body (Did a vagcom alignment) as well as some other insignificant maintance.
Car ran fine for weeks after, but recently it has started to bounce around randomly at idle. Like 650rpm(normal) for a few seconds. Then it will Slowly climb to 800rpms, hold there for a few seconds. Then back down to 650ish for a few seconds, then back up to 800 for a few seconds. And so on. It's very subtle and very random. Then sometimes when accelerating, I can feel it in the gas peddle. Like a slight pulsing power loss. Very slight and of a similar rhythm to the idle issue.
I do have a check engine light for Load Calculation cross check-p1143-001 upper limit exceeded. But that has been a battle I have been fighting for a year or so, and I think that is some kind of vacuum leak, but this rpm issue just started a few weeks ago. The only thing I was thinking so far is that when I was doing the plugs and coil packs, I noticed that there was a slight bit of what looked like dielectric grease on each coil pack already from the factory. So I didn't put any more in the coil packs sleeve part that fits over the plug. So was that a mistake? And if it was a mistake would this be a symptom of that?

I have a 2012 Camry LE. When I let off the gas between 25 & 40 mph, the transmission aggressively brakes. Occasional acceleration surges when braking. And when I need to go, it sometimes does not want to go until I punch it. All problems are sporadic.

My 1992 Chevy truck started surging or revving up when in park. It will tac to 1000 rpm's then go back down - up and down. It won't barely drive down the road. Didn't know if this is a fuel pump problem or something more serious. We've replace several parts that were described on the internet as "could be the problem", but nothing has worked.

My 2002 chevy venture does not provide any heat from the cabin air system..The engine reaches proper driving temperature normally.Can't heat the cabin or get any modulation of cabin temp when using A/C.

My 2001 Chevy Venture van is accelerating on it's own and is now overheating. The heater works, the AC works but the defrost doesn't. I can be at a dead stop, put it in drive and it starts going on it's own, even up a hill. It's also developed a 'knock' or 'jump' with it automatically shits gears. I simply cannot afford a new engine, we did that last year when it overheated and blew the gaskets.

My mini van after driving it say 20 miles, starts shifting kinda like its slipping every know and then, and check engine light comes on. Its ok until about that first 20 miles, before that its ok.

I have a misfire on cylinder #5 on my 03 Chevy Venture with a 3.4L, I changed the #5 Injector because the shop I took it to said that's what it was. But the same code came back for misfire cylinder #5, would a bad plug or wire cause the same code to come up.

My 04 Chevy Venture has started smelling of gas when I drive. It doesn’t happen all the time. I can drive to a destination and smell nothing, park, and a few moments later leave and smell the gas. I have had the fuel lines checked and was told there are no leaks. The smell is stronger when I have the vents pointed at me, but if I switch to the floor vents, it diminishes.

I am having issues with my 2002 chevy cavalier.
The car occasionally surges forward while idle and revs up to 1500 rpm approximately occasionally when the air conditioner is on... if the brake is not applied I move forward.. the lurches are continuous every 3 seconds or so.
I am getting a code for an evap leak.. I have replaced the purge solenoid valve, gas cap, and checked all connections with no luck... slightly decreased gas mileage has occurred.
A little bit of a slick substance has been leaking from the car.. it has the consistency of water, but leaves a slight brown tinge on concrete.

I recently bought an '09 Santa Fe Limited. I want to love the vehicle, but I've got a problem with how it drives. Basically, here are the symptoms:
1. Engine RMPs dance around about 200 RPMs at idle. (I was told this is normal. I don't think it should be.)
2. Under normal acceleration, it bogs down immediately after shifting into 2nd gear and after a couple of seconds there is a surge and acceleration seems "normal."
3. Occasionally, I feel subtle fluctuations or surges in the engine under both acceleration and/or cruising speed (any speed, really.) It's like I'm feathering the throttle when I know I'm not. This is most pronounced when under a load, such as taking off from a stop sign at the bottom of a hill and accelerating up the hill.
So, here's what the dealer has done to address the issue.
1. According to the Carfax report, the previous owner had the throttle position sensor replaced at 22,000 miles and again at 27,000 miles. I bought the vehicle with just over 30,000 miles (certified pre-owned).
2. On the day that I bought the vehicle, I noticed the issue and the service manager took it for a test drive with me. He told me it was wind buffeting that I was feeling. I thought that was bunk, but with it being a higher profile vehicle, it put some doubt in my mind. He went ahead and flashed something to reset the adaptive learning module that supposedly adjusts something in the engine based on how you drive. It seemed better after that, so I went ahead and bought it.
3. After a few weeks of driving it, it became clear to me that it was definitely not wind buffeting, so I scheduled a service appt. It was taken for an "extensive" test drive (according to the service record) with a diagnostic computer connected. Apparently, the service technician said they were only able to find one small blip with the mass airflow sensor, so they replaced it and called it fixed. I should also note that at no time, have any codes ever shown up when they check for error codes.
4. Although it seem slightly better, the problem still exists. Just for kicks, I dumped a bottle of Seafoam in the gas tank with my last fill up, but that doesn't seem to have made any difference.

I have been having problems for about 1 1/2 months. My dash gauge never indicates it is overheating. Within this time both heater hose tee's have broken. One of the new ones only lasted about 2 weeks before it broke on all 3 connections. Now the heater hose connector broke. What could be causing this?

My engine will occasionally lope at startup. If I look at my scanner the fuel trims will suddenly go negative up to - 20 and then the engine smooths out. It seems to happen in open loop and when in closed loop the fuel trims balance out. I changed my maf sensor, but it did nothing. I don't smell any gas, no Check engine light.

I just finished replacing the head gaskets and all gaskets above it on my Chevy Venture. When I went to start the vehicle the first time nothing happens. The dashlights come on, but when I turn the key to start nothing happens. No clicking, no nothing. I have tested the battery...OK. I have tested the starter...OK. I have traced the wiring harness to ensure all wires are plugged in. I have checked all the fuses. I thought maybe its the gear switch so I changed down to 1st and then back up to Park...Nothing. I jiggled while in park..Nothing. Could it be the actual ignition switch? It was fine before this escapade.

I own a 2003 Chevy Venture minivan that had the front left tire go flat yesterday. I backed out of the parking space and drove a few feet before realizing we had a flat and then immediately re-parked. The spare was bad (rusty and flat) so I had someone take me to Goodyear to replace the tire (it had a hole on the inside sidewall and was not repairable).
We got the tire on and drove the 30 miles home - as I was driving, I noticed that there was a slight vibration and a buzzing/humming sound coming from the front of the car. It definitely changed pitch/feel as the car sped up or slowed down.
I'm going to take the tire back off today and inspect everything to make sure everything is in place, but what might be going on? Bent rim? Tire balance?

I have a 2001 chevy venture (254,000 miles) that has me baffled. It has been a great van but it started about a month ago sputtering and bucking and numerous times shutting off. Most times the engine light would NOT come on. It would get the hiccoughs and start bucking like someone learning to drive a stick shift for the first time. Once it sputtered hard enough to throw off the serpentine belt. I put a new timing belt on it last year when I redone the intake manifold gasket. Now its not shutting off but it has only about half the power it should and the engine light is starting to come on more often.
It bogs down and then it will try to go then bog down again. The engine light blinks for about 20 seconds then stops and goes out. When the engine light is on and stays on the code most often says system too lean, and a egr flow insufficient. It does have a vacuum leak in the hose going to the egr. Have ordered that, hasn't come in yet. Gas mileage is horrible. I have done new plugs, fuel filter and cleaned the K&N air filter. Someone suggested the catalytic converter. I dumped in a bottle of 'Cata-cleanse' from Autozone. No difference. A friend of mine had a venture doing the exact same thing. It was in the shop for 6mo with no luck. But his straightened out on its own and is running good now. I really don't feel like waiting 6mo to see if this will straighten out.

. My "piece of junk" (as my husband refers to it) 2002 Chevy Venture broke down on me last year. It felt and sounded like a tire blew. There were no warning signs. It was very sudden. I had it towed to where I was buying it and they told me the motor was blown because I had let it run out of oil. I knew this wasn't the case (letting it run out of oil) and so I brought it home. My husband discovered the oil pump was not working but before I could afford to put one on to see if this fixed it, it was repo-ed as I had lost my job for no transportation. For about a month, the car lot intended to take the vehicle to auction and then sue me for the rest.
I was finally able to work out an arrangement with them where they held the car until I got my student loan money and paid for it. When I got it back, I expected it to start and to be able to try the oil pump. However, now it will only start when you short out the starter, runs for a second and dies. During these brief seconds, we discovered that the oil pump is pumping oil. I have a theory that while they intended to sell the vehicle, they started to fix it. But why will it only start if the starter is shorted out and then not continue to run? Will a new starter solve this? And could the motor completely blow up in a matter of minutes from the oil pump going out?

I have an 04 Chevy Venture. Recently it started making what I can only describe as a grinding. I have been a mechanic for over 30 years, working on everything from motorcycles to heavy construction equipment. This is a new one on me. I have checked the wheel bearings, brakes and rotors, and suspension. All good. I have blocked her up and put it in gear, and the noise seems to be coming from the transaxle. Fluid is cherry red and is not burnt, no metal shavings, and not low. I have noticed that while driving, if I jog the wheel left or right, it quite until you straighten out again. If I weave back n forth going down the road, it's pretty much non existant, but the cops are starting get suspicious.

My 99' Venture is leaking antifreeze and was overheating. Ok, so I figure it's something as simple as replace the radiator cap or something. My mechanic says it looks like my manifold gasket is due to be changed AGAIN. If I had one going into the other then I could see why we're talking oil when I'm talking antifreeze. I parked the car cause I have a second car. So the Van sits for 3 months and leaks into the pan I put to protect my driveway.
I could probably have filled a quart container with the puddle created. It looks Orange so yes it's antifreeze and yes it's SLIGHTLY milky when you shake it around. It doesn't show any sign of oil. BUT when I check the oil on the dipstick it's perfectly fine. The car wouldn't start so you'd say jump it right? Did that and nothing, bought a brand new battery still nothing. So I had it towed to a Mechanic. If he can't find it I'm going to plan B, let the dealer diagnose it, get a quote and take it from there.
