Cavalier - Chevrolet :: 2002 - Surges Forward While Idle & Rev Up To 1500 Rpm?
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.
Airconditioning :: Car Surges / Lurches Or RPM Shoots Up To 1500 - 2000
Vehicle : 2005 Five Hundred (220,000 miles)
Symptom : Car surges (lurches or RPM shoots up to 1500-2000) when outside temperature is 75+ F and ONLY when A/C is on. In addition, when outside temp 80+F, A/C occasionally not as cool, and engine temp goes to HOT (nearly overheating. Shutting off A/C gets engine temp back to normal and surging issue goes away. Less frequently, car's RPM drops to nearly stalling and on a couple occasions the car actually stalled. Symptoms began around 100,000 miles. Lastly, this happens ONLY when at idle (usually in gear) or when coming to a stop or driving slowly, like in a parking lot.
Corrective steps taken to date: - Throttle body cleaned by dealer mechanic (I'm not 100% sure it was a thorough job.) - Thermostat changed. - A/C recharged. - Belts & fans checked - OK. - Engine computer reset (?) - battery disconnected by mechanic for 30+ minutes to "reset" computer.
This has been going on for at least 3 years now. I've been to my Ford dealer and an independent mechanic's shop numerous times for this. The dealer was never able to reproduce the problem. The other mechanic finally experienced the surging. Oddly enough, after each visit to the shop, the car seems fine for the day and then the symptoms begin to return in full force!
Lexus GX 2004-09 :: Engine Stumble Only At 1500 RPMs If In Park Or Neutral
What could cause this? I have 100k and I only notice this if in park or neutral at 1500rpms. It goes away before and after and it seems to drive very smoothly. I had a bad alternator and I just replaced it but the "new" one is making a high pitching ringing so I'm having the shop change that out for a new oem. Any chance it's the alternator or could this be something else. I have sea foamed the throttle body recently and cleaned the maf recently and changed the air filter. I didn't do plugs but they are do at 120k

1999 Chevrolet Silverado 4.3 ltr ....
I was riding along the other day at about 40 mph and my engine just DIED. No sputtering, jerking, lurching, etc.. I have a 1999 Silverado 1500 4.3.
Since then I've tried swapping the fuel filter out. When I took the old one off I did the blow test and could barely get a bit of air through it. Put in a brand new one. Still won't start. It cranks but it won't turn over. It's like it is starved for gas I suppose.
All electrical faculties are functioning seemingly normal. (Of course I have to charge the battery every time I want to try and crank it because it doesn't charge itself because IT WON'T CRANK!)
I've had to change the fuel pump twice in the past 2 years. The last time was about 5 months ago.
For the past week or two my "Change Engine Oil" light has been on even though I've had my oil changed a month ago.
Chevrolet - 1500 :: Oil Pressure Goes Down As The Engine Temp Increases
I have an 88 Chevy C1500. It started showing low oil pressure about a year ago and I went with a heavier oil and oil pressure go a bit better.
Just changed the oil and now, when I start the engine cold, I show normal oil pressure. As the engine temp increases, the oil pressure goes down. When engine is fully warm, oil pressure shows 0 and "check gauges" light comes on.
Decided to put even heavier oil in but guy at parts house said it was probably the sending unit, not a worn out engine. I tend to agree because I drove it more and never hear any ticking or valve noise. Too cheap to replace the sending unit.
From the symptoms above, does thus sound right? Could the sensor somehow fail as engine temperature increases? Everything I read says oil pump failure is very rare.
Chevrolet - 1500 :: New Clutch Will Not Disengage While Engine Is Running
I just installed a new Sachs flywheel and clutch on my 1995 Chevy 1500 4x4. Got everything back together, filled up tranny fluid and gear oil, bled the clutch till no air came out and it still won't shift while the engine is running. I can get it into reverse with a little grinding when in 4H, but that's it. The stick moves freely when the engine is not running. Checked the master cylinder and it is moving just fine. I have checked and did not install the clutch plate facing the wrong way. Any other guesses on what I can do before I have to drop the transmission again and redo the whole install?

I have a 2001 Chevy 2wheel drive 4.3 V6 Pickup with a long lasting engine knock. I use it only to haul trash and building materials, maybe once every other week. The knock is sporadic. If I take a long trip and drive on an interstate highway the following morning upon start-up the truck will knock heavily and continue to do so as long as it is running. If I take the truck for a short local trip, the following morning it will start with no knock and only start knocking after driving maybe 10 miles. If I drive only short trips, the truck will almost always start without knocking and only knock once it is fully warmed up. I purchased this vehicle from my brother who drove it this way ever since he purchased it at a salvage auction (full of dents and some damage) who put over 20,000 miles on it with this same engine knock.
Other than the dents, the truck is in great shape, no rust, and has 118,000 miles on it. I would like to keep this thing because it was very cheap and I only use it sporadically. So, I'd like to know if I'm going to eventually have to put a motor in it or if there is some small fix I could make to stop this knocking sound. The sound: It is heavy. It sounds bad. It knocks along with the rpm of the motor. My brother, who is also a great mechanic, thinks it may be piston slap or something in the valve system. I've also had a mechanic listen to it. He thinks it's a rod bearing or wrist pin. What I don't understand is how could it be any of those things when it makes a difference how I drive it the last time it was used? Could it be something simple like a vacuum issue, knock sensor or crank sensor?
Chevrolet - 1500 :: 1996 Chevy Engine Hard To Start When Cold
I have a 1996 Chevy Cheyenne pickup with a fuel injected small block that has 50k miles. Earlier this summer the truck developed a problem where it is very hard to start when cold (after sitting overnight or after sitting for many hours on my flat driveway). When the engine is cold (say the first start of the day) I can only get it to start by giving small bursts of cranking power to the starter. That is, it won’t start if I hold the key in the cranking position but is more likely to start if I give it a short burst of cranking power (when I hold the key in “start” position) for a second or two.After the first start of the day, the engine runs fine and subsequent starts are quick and normal. The “Check Engine” light is not on and there are no trouble codes…. Other than hard starting there are no issues with engine performance.

I have a 2003 Chevy 1500HD 6.0L 4x4. I've recently started getting the "Reduced Engine Power" light along with the P1516 Fault code. I've checked all the wires going to the TAC Module, TPS, and MAP, all appear to be in good condition. The Throttle Body is clean and the "flapper moves freely with no sticking. I only have this issue when it is warm outside. Recently we've had fairly code days between 32-50 degree weather but on the few days that it has gotten warmer, I've had the issue. Since it seems to only happen when its warm, I believe it to be a moisture issue, but I'm not sure.
View 6 RepliesChevrolet - Venture :: 2000 3.1L - Surges On Acceleration
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).

2007 Chevrolet Impala 1LT3.5L Flex Fuel EngineAuto Transmission with shift lever on the steering column29,980 miles
Bought new Nov 2006 so is now four and a half years oldThe drive train is still under warranty (6 years or 60,000 miles). All recommended service per the manufacturers manual has been done. Book calls for first transmission service at 50,000 miles
NOTE: Previously at 19,600 miles the transmission cooler line fittings were replaced due to a small leak. Currently no evidence of a leak; no fluid on garage floor and the transmission fluid level on the stick shows right on the mark. Fluid still clean pale red and has no odor.
Majority of my driving is short hops with multiple stops, so the car gets heavy use shifted into and out of park gear. I do use the "parking brake" applying it after shifted into park and released before shifting out of park. I always have my foot on the brake pedal when shifting out of park.
PROBLEM: Having trouble shifting out of park on a cold engine or if the car has been sitting for an hour or more since turned off and put into park gear. Oddly enough, if I'm running a series of errands where the car has been in park for only 5 to 30 minutes, there is no problem shifting out of park gear. But if the car sits long enough for the engine to cool then it becomes hard to shift. The longer the time it sits in park the harder it is to shift out of park when the car is started.
Chevrolet - Venture :: 2003 - Idling High At Times / Engine Very Loud When Put Car In Park
My Chevy Venture 2003 approx 120 thousand miles is idling high at times. It will drive fast. I can feel it speeding up even when I am not pushing on the gas. When I put the car in reverse it flys backward (I have to keep my foot on the break to back up at a safe speed) and then when I put the car in park the engine is VERY loud. Again, this does not happen all the time. Usually when I drive it over ten miles. I thought it might have something to do with the AC, but I played around with that (driving with and without the AC) and that did not factor in it.
I took it to my own personal mechanic and he couldn't find anything wrong with it. I then took it to a dealership and they said they couldn't find anything wrong with after doing their hundred dollars worth of diagnostics and said they needed it to actually be doing it..what they called a hard fail...for them to know what was going on. . They drove the car for quite some time and nothing happened. I drove it all this pass weekend and nothing happened. It might go a week or so without doing it. Thenn it does it. Usually I can turn the car off and restart it and it will be back to normal. The check engine light is NOT on. Any clue as to what might be going on?

View 13 RepliesAzera HG (2011-16) :: Howl Noise Between 1000 - 1500 RPM Whether In Motion Or In Park
I just took delivery of a 2015 pewter gray base azera. It is my second one as I purchased a leftover 2013 last year. The sonatas had to go just not comfortable enough for me. Between 1000-1500 rpm whether in motion or in park I get a sound like an owl hooting. my 2013 does not do it.i can make it do it any time I want. This is really annoying in traffic it actually can be heard with the radio on. the dealer said it is normal and let me drive another new one on a test drive and it does it too. Almost sounds like it could be a harmonic noise in the intake or exhaust. Going to see if I can pinpoint it this weekend. I am very disappointed as my 2013 has 36k on it and other than the rattle at start up no issues.

View 2 RepliesChevrolet - 1500 :: 1997 - ABS Light Goes On And Off?
I have a 1997 Chevy C1500 with about 85k miles on it. I had the breaks checked and replaced over a year ago and this problem is pretty recent. When I got the brakes done I had the pads replaced on the front disks and I had the back drum pads and some brake part replaced that was inside the drum. Looked like a little hydraulic piston of sorts (sorry, not to up on my car lingo here lol)
My issue is my ABS light comes on from time to time for no apparent reason at all (at least that I notice). I can be just sitting at a stop light and I will notice it comes on, stays on, then randomly will go off. The car seems to break fine, especially at higher speeds (30-70mph). On occasion however at low speeds (5-15mph) when coming to a some what sudden stop my brakes seem to skip? Kind of feels like a grinding feeling. No gravel or slick road, just plane ol pavement. I think this is the ABS system but Ive only ever driven one other car with ABS breaks that the I believe the ABS system activated while stopping on ice and it felt the exact same.
I have not noticed if the light comes on during these low speed stops, as I am just now putting all these pieces of a puzzle together to figure out if something is really wrong with my ABS system or if its just a sensor or something.
