Having some issues with my 2003 Alero 4 cylinder. Upon start the entire engine shudders and the check engine light flashes. I have to turn it off and turn it on and it will stop most of the time. I've taken it in and the mechanics can't get it to reproduce the same issue for them. Just replaced all four plugs, boots, ignition coil.

Our car recently started shuddering/vibrating at speeds over 45mph. Once the shudder begins, it continues for the remainder of the drive. It doesn't feel like it's in the wheels or the steering column, and there are no warning lights on the dash. It seems to be more intense when braking, as if something were fighting the inertia of the vehicle. There's no difference in the sensation when driving around corners.
After a few minutes of driving, there seems to be a burning rubber smell that is concentrated near the windshield in front of the driver's seat. I suspect that something is damaging a hose with heat or friction. I'll be taking it in to a mechanic.
My mom's 2003 Alero has had a bad catalytic converter for the last few years.. at least that's what she was told when she took it to the shop. The engine light (P0420 threshold below efficiency) has been on over the last few years and I occasionally check it with a code reader to make sure no other codes have been added. Up until today - as far as I know - none have been. Now today when she was driving it the engine light started flashing and running rough and making a knocking sound.She brought it straight home and I hooked my scan tool up and it gave the same cat code as I just mentioned, plus a P0306 misfire code. So I pulled the plug wire on number six cylinder and hooked up a spark tester to it - and it showed a decent spark. And to verify the spark being normal, I tested at another plug wire and the spark looked about the same..so I don't think anything is wrong with number 6 plug wire or coil or anything like that but am not sure. Also, the spark plugs were replaced a couple of weeks ago because the ones in the car were worn down about .010''. I can't imagine this having anything to do with the misfire because I did them myself and made sure they were gaped properly and that all the wires were put back on the correct plug/cylinder and plus it ran fine after the plugs were installed - but thought I would mention it anyways. And I was very careful not to damage the platinum on the plug when gaping them.
Did a little bit of research and found this: A code P0306 may mean that one or more of the following has happened: Faulty spark plug or wire Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector Burned exhaust valve Faulty catalytic converter(s) Running out of fuel Poor compression Defective computer
My 2000 alero was WAY low on oil so I added a quart then drove for about 45 mins at 40 mph the car seemed fine. the following morning when I went to start it the car turned over but would not start when it finally started the engine knocks and it is putting out a lot of white exhaust. obviously I need to see a mechanic but what might be wrong. my neighbor said one of the cylinders isn't doing what ever it is supposed to do he said it passed a compression test but I don't know what that means...
View 3 RepliesI have a 2001 ford taurus. just changed the engine with a used engine has 130k, did tuneup changing all spark plugs, wires and distributor cap. Also changed the 02 sensor upstream. And the check engine light remains on. if i start the car and it idles the check engine light flashes. but once i drive it, it just remains on. brought to the mechanic and he put on the machine and it reads that the problem is the 02 sensor upstream and the spark plugs misfiring. my mechanic is lost not sure what the problem is. someone told me it could be the manifold gaskets and pedlum gasket.
View 1 RepliesI go in this week to recheck my nagging check engine light. Flashes after a warm start, then stays on. Been there once already for it, it has come on too after a cold start... Last time they said it was a very vague miss fire code.... It did shake a bit... On the plus I get to drive a nice new Elantra again.... On the down, I never want my car back after driving it ...
View 2 RepliesMy car has 120.000 miles and regular maintenence done on schedule. Yesterday, after a 1000 mile / 4 day trip, after a break at a service station, the engine srudded violently (for being a prius, it felt like a diesel) while cranking up durin acceleration.
The check Engine light came on.
Using Can-view, I noted these DTC codes: P0101 C3100 P0000
And cleared the memory.
The check Engine switched off.
For the past few months security light of my 2003 Alero keeps on activating preventing the engine to start or it doesn't even crank.
I always do the reset technique..."Turn ON the engine key for about 20 minutes and wait till the flashing security light become solid before starting the engine." Today when I started the car the security light comes ON and stays on for my whole 50 Kilometers travel. When I reached my destination,I tried to turn ON and OFF the engine waiting for my luck to have the solid security light to come OFF,but no luck.
Will this problem have any effect on the performance of the car? Will the car stall while I'm on the road?
2012 Prius Gen III 38,000 miles, check engine light came on. Drove car to dealer and they came up with error code 0456. The explained that a rodent (I live in a rural area) chewed on a hose which is causing a leak like a bad fuel cap.
To solve this problem they recommend that the entire gas tank needs to be replaced. Does this seem reasonable? It seems to me they are saying that the chewed hose can not be replaced.
My 2001 alero 3400 engine is getting hot again this alero is running with a 2001 impala engine run great for few months, replace radiator, hoses, thermostat and suddenly coolant start leaking in the overflow, fans not working even with ac on, i replace the etc sensor and did not work, the fans turn on when I disconnect the etc sensor so i think the fan motors are ok. I got one pcm module from the salvage yard in case I need to replace it but I read that only the dealer can reprogram the computer system because vin number issues....
View 2 RepliesI have an 01 olds alero, I been having problems with the engine stalling out. i was told it may need a new fuel filter so I replaced filter and now it idles rough till it stalls. What to do next? I replaced the plugs 2 years ago also.

View 2 RepliesI got a 1986 Camaro 5 speed 350 4 barrel carb and the check engine light flashes on and off, when it comes on the engine idles really low and when it goes off it runs normal. I've changed the ignition control module twice already because it wouldn't start. i change the ignition coil because thought that was messing the module up. I hooked a obd ll and 1scanner too the car but wouldn't respond.
View 14 RepliesI have a BMW 740I that has over 200,000 miles on the clock, I have noticed in the past couple of day that the check engine light when I turn on the ignition that it flashes then becomes still, what the problem could be, and if it is safe to drive?
View 9 RepliesWhile I am driving the car it will start to die and skip. Happens randomly. Today I was driving up a small hill and it went quits on me started lurching with check engine light coming on and off. The car will turn over and start, but only for a few seconds before dying again.
Seems to happen when the car is running for a while. Also the ABS light flashes on then off randomly while driving sometimes although It hasn't been an issue. Will be checking tomorrow to see if it starts.
I am a grad student hoping my car will hang in there till graduation next year. I have about 227,000 miles on my Honda Accord Wagon and recently the odometer stopped working, S light started flashing, and the check engine light came on. This only happens sometimes, and the check engine light does not always come on when the S light flashes and odometer stops working. I've continued driving the car to see what happens and so far, no problems have come up. I have driven another 1000 miles and am hoping I can just ignore the problem and continue driving the vehicle since I am not in a position to fix it or get a new car.
Recently I passed my California emissions test and she seems to be running smooth. Any thoughts or warnings as to why sometimes these signals happen?
I have to drive with GPS on all the time to know my speed, but other than that I feel OK.
I was in cruise control at 50 and pressed and held the increase speed button to pass a car and once i got to 55 and still holding it the check engine light flashed twice a second until i released the increase speed button. Are you not suppose hold that button? Could this be APR related? I also noticed that the speed doesn't matter, it could be at any speed just hold it for like 5 seconds...
View 4 RepliesI have a 2003 Jaguar X-type that gives me trouble when the temperature drops below 32 degrees. I have to warm it for at least 10 minutes. During that time it coughs and sputters and my check engine light flashes. Once the light stops flashing I am able to drive. What is going on?
View 5 RepliesMy wife was about to go into work today and when she started the Accent she said it started rough and revved up two or three times and the check engine light flashed 5 or 6 times. The light stayed on solid after that but there was no loss of power, smoke, low gas mileage or vibrating or any other symptoms after initial start up. I plan to take it to an auto parts store tomorrow (the car is at her work about 20 miles away) and get the code read. What I may be in for? I'm hoping its something simple. I told her to check the gas cap just in case.
View 24 RepliesMy 2004 Cadillac CTS 3.6L started running rough, check engine light flashed on and off. Codes P0300 and P0303. The car has about 119000 miles. Could this just be the plugs? The car has been running fine up to today.
View 2 RepliesI just bought this car from the original owner. She didn't take that great of care of the car. First oil change was done at 8,000 miles for example. Basically if it was broken she would fix it, but didn't do much preventative maintenance.
I just replaced all 4 spark plugs and coils since one was misfiring and didn't want to have to go back in and replace one in another few months. Replaced the AC belt a few days ago since it was cracked and worn. All other belts are fine. I drove the car around for a few hours the next day and it ran great.
Today, the check engine light flashes and then stays on. The car is idling rough at stop lights and acceleration is poor. Previously, the light came on and it was the EVAP system. Not sure which component and I was told it isn't supposed to affect the way the car drives.
