Cavalier - Chevrolet :: 2002 - Surges Forward While Idle & Rev Up To 1500 Rpm?
Sep 23, 2016
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.

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.

After my truck sits overnight it starts immediately and goes to fast idle for a few seconds, then ithe idle starts dropping until it gets to approx. 400 RPM.If I drive off immediately it will correct itself in a short while, otherwise I need to baby the engine speed until it runs on its own - usually five minutes.I cleaned the MAF and performed a MAF tap test with no success.

I have a 2004 Chevy Cavalier. I am having some issues with it.
When it first starts it idles really hard. The RPMs are up and if will try to accelerate without hitting the gas. This stops after the first minute.
The second part is that when stopped, but in drive, it idles hard. It does it though when the AC is turned off. You can see the RPM gauge go above and below the normal 500 RPM. If you turn the AC on then it levels out. It will occasionally idle hard with the AC on, but rarely and not as much.
The car drives well and is not overheating.

This is my daughter in laws car. The rough idle, check engine light and trac light all happened at the same time. She was in a parking lot and drove over a speed bump when all the problems started. The check engine light flashes when driving above 25mph. It's on solid at idle. I found the EVAP purge valve plastic nipple was busted off so I replaced the assembly. I was totally surprised when this had no effect on the symptoms.
I find it strange that the car was running fine and then has all these symptoms after going over a speed bump.

I've been fighting this almost a month now.2.2L Engine.
The engine turns over, but want start.
We have fuel pressure (55psi) and a spark.
Sprayed ether in the intake -- nothing.
Changed the crankshaft positioning sensor. Put a simple scanner on it, it stated no errors or faults could be found.
Tried another ignition module, checked the PCM fuse and ignition module fuse, both look fine.
Installed an anti-theft system bypass and followed the reset instructions. Didn't fix.
Just for fun we changed the spark plugs as well.
Now, the person I was with who saw the spark (I was inside the car) says the spark looked "weak" to him. Is this possible?

Why my 2002 cavalier keeps blowing the ERLS fuse?? Happened a while ago, and I heard the pop. Then my check engine light came on, along with the off track light and the air started blowing hot air, and it won't shift out of first gear. It is an automatic. I replaced the fuse, quit using the A/C and it ran for a couple weeks but not real far. Then after a 6-8 mile round trip it blew again and I can't seem to find any answers for a very odd problem.

I have a 2003 Chevy Cavalier that I have owned since new. It has 340,000 miles and I want to get to at least half-a-million. My wife was driving it last week and it started with a very rough idle and ran rough for 5-10 minutes until it quit running for her in the bank line. I came to get her and the car and started it by giving it some gas, but the idle was rough and jagged. Feels like it missing and gasping for air. Running on the road home at 30mph it seems almost normal, until i slow to a stop. Went to have the codes read at Advance and Auto Zone only coming up with PO440 woe the EVAP system, which has been showing for 200K miles. Have a clean K&N filter but no other modifications. I've done a lot of work myself and also have a good mechanic, but I don't want to drop if off blindly. I'm thinking maybe the Fuel Pressure Regulator or the IAC Valve. Haven't looked at the throttle body yet. Where should I go from here?

I have a 2002 Chevy Cavalier that stalls ever time it is fueled at the pump. It then continues to stall. I have to pump the gas like the old days when we all had carburetors and repeat the action many times. It always starts eventually, but causes unnecessary anxiety so I always fill my car at a time I don't need to be anywhere in a timely manner. It was taken to the shop but they could not reproduce the stalling, as they did not have the information that it mostly happens at the when fueling. The gas cap can be taken off for a while and it starts okay. The rpm is low after adding gas, if you give it gas, it runs then eventually idles normally.

I have an '02 Chevy Cavalier whose passenger side headlight went dim suddenly one day when I started the car. When I start the car, the daytime running headlights indicator flashes and clicks, and then the service light comes on. I have tried the following:
1) Swapped light bulbs between the two lights. It is not the bulb.
2) Swapped fuses between the two lights. It is not the fuse.
Even stranger, when I remove the fuse to the dim headlight, the light stays on. My guess is that I have a short somewhere in the wiring. I took a brief look at the connection between the socket and the wiring and everything looks good there.

I have a 2002 Caviler. Somewhat recently the car has been not staying at a constant temperature. It will rise above the middle (where it would always just stay at until recently) a notch and then go down a notch below the middle. I have never replaced the thermostat and I have had it around 8 years and the car has around 60,000 miles. Did replacing the thermostat fix them?

I recently bought this cavalier about a week ago its and 88 automatic trans with 1.8 4 cylinder I thing not that it matters much. I noticed the exhaust had a smaller pipe from the manifold and the rest was strung with a bit bigger pipe and was attempted to crimp the pipes togather it was loud so I crimped thhe pipes better and used exhaust glue to patch the holes it runs better now to a point. but when I start the car it revs up a fair im guessing 3 grand since I have no rpm gauge but then it dies down to a low idle to the point were the car shakes a little bit.
with the exhaust fixed I can get it up to 20 kilometres an hour with my foot off the gas when I turn fully it wants to lurch ahead/backwards. when I took it out for a highway drive today I came to a stop sign so I slowed and stoped and the car stalled out. started no problem. but I also tried later putting it in neutral and it doesn't stall as I role to a stop it doesn't shake in neutral. I would like to have this fixed but I need some pointers as of were to look. im not sure if this means anything but when I got the car it had a bad enough radiator fluid leak at the hose meeting the heating car on the engine side of the fire wall I repaired that and no longer leaks.

My 1995 chevy c1500 cuts out at idle or the moment the brakes are applied to shift into drive. I replaced the passenger wheel cylinder and bled the brakes and it ran fine for a few hours, then the idle problem stated again. I have check the map senor and a few other electronic component as my mechanic said the problem " might be electrical."

2004 1500 5.3 low oil pressure after using Lucas engine stop leak. No pressure at idle just below 40 when driving. Replace the sending unit and pressure improved for about a day. Just had a manual pressure gauge hooked up and it shows the same as cluster. No engine noise at all. I was informed that using Seafoam or another solvent could loosen up build up and cause damage. Trying to find out if using an engine flush machine may support. I am assuming that the cause of the low oil pressure is due to build up from using several qt of the stop leak over a four months. I am the only owner and I have always changed the oil according to schedule and have always used Valvoline synthetic.

I have a 97 Chevy K1500 truck that i have been having problem with starting. Sometimes it will start. When it does the idle is rough. When i put in in gear it almost acts like it will shut off. Then it comes back and it drives fine. If it shut it off it may or may not start. I had the distributor cap a rotor replaced. Then I replaced the spark plugs and wires. Still does not start. It seems like it is getting too much fuel. I pulled the fuel pump relay and the truck would start then die out. When i put the relay back in truck does not start. I am not sure what might be the next piece to look at. I was thinking the MAP sensor or the throttle position sensor. So far i have not had any codes come up.

2002 CAvalier 2.2 automatic with 123'000 miles. I was asked to look at this car for a slipping trans problem.
I drove the car about 3 miles and in 1st and Reverse it feels normal, even on a steep hill, but once it shifts into a higher gear the trans slips and you can go only about 15mph.It is shifting, because if you move the shifter into a lower gear while traveling....you can feel it downshift.
There is a code of P0502 Vehicle speed sensor. and there is no Trans fluid visible thru the filler cap on the trans top.
Previously someone else worked on this car for the slipping trans....changed some sensors....but couldn't fix the problem. The owners don't know what parts he replaced. He works for a Tire outfit and I've known him to lean towards used parts a lot.The previous mechanic convinced them that it needs a new Cluster. I presume he means instrument cluster.
I have a feeling that he just threw parts at it hoping that something would stick.
I presume that he replaced the VSS, and it didn't cure the problem.Come to think of it....the code could be from before the other persons work. I should have cleared the code and test drove it again.
I'm looking at dropping the pan, replacing the filter, refill the fluid, and replace the VSS
My questions: Could a instrument cluster have anything to do with the shifting problem.
Is the level of trans fluid supposed to be above the ledge under the filler cap, or is there a "full level" plug in the side of the trans. If he replaced the VSS with a new one....and the fluid level is good....whats my next step.

I just bought a 2009 Chevy Silverado , have only had for a week and have noticed an irregular fluctuation in idle, also the transmission has lack of a better term jarred a few times and seems to downshift rough sometimes. The irregular idle seems to be worse when the ac is on, I can hear the compressor kick on and off alot. And just once I was driving and tried to accelerate and it didn't want to very much. Factory warranty is out and dealer didn't give option for extended warranty. They have agreed to look at it but aren't willing to do much other than clean injectors and throttle body.

What can cause a car to jerk forward while accelerating? Other symptoms include loss of HP and MPG. Recently had spark plugs and wires changed. Regular maintenance. I am about to see my mechanic and ask him to check the fuel pressure.

I have a misfire in the 6 cylinder on my 98 Chevy c1500 5.7l 350 v8 2wd. I changed the spark plugs and wires, cap and rotor, and changed the spider injector i put the spider injector in from another engine I had. After doing all this the code still comes up. The truck runs fine and except it idles slight rough not bad at all and now it says I have a vacuum leak and while I'm driving you can feel the loss of power. I tried all the ways to do it like on YouTube. What is wrong with my truck?
