I took my car to a certified GM dealer to get it serviced. I had been having problems with the car sputtering and wanting to turn off upon acceleration, especially when driving up hill. The problem was identified by the dealership. Supposedly GM says the problem is very rare. There was a special bulletin issued by GM about this problem.
The car started hesitating then engine light started flashing. Along with it wanting to turn off at a complete stop. Haven't fixed it yet. Just happened
My car misfiring and they haven't been able to find the problem
3rd cylinder not responding after maintenance, taken to engine shop, engine is misfiring
engine misfire, engine light came on. Had coil 3-6 changed. a week later, having same problem with misfiring. will be going back to ask about ignition module
While trying to pass a vehicle my 4th cylinder misfired and i lost almost any acceleration. diagnostics then found error codes for the multiple misfire and misfire of the 4th cylinder and another error code for failure of the catalytic converter. i replaced all the ignition coils and the catalytic converter to fix the problem
Engine misfire on cylinder 2 engine light is on and blinking
engine misfire caused by coils. I have had the check engine light come on, on several occasions and the DTC code were for coil packs. I have replaced the coils but still have the code. I have determined that the cause is the Ignition Control Module (ICM)
Engine misses when warm only in summertime. Begins to miss on acceleration from stop.
To whom it might concern:
I was experiencing all of thee misfire problems and replace all which might cause the, it was not until check another sight out which offered possible solution I had not considered; Verbatim:
" Number 1 injector harness control wire( black) has a break in it causing all the above issues. You can replace the short harness or find the break in the wire and repair it. I found the break in the harness about two inches back from connector, it makes a hard bend back in to the loom".
I took the advice of the person who delivered the above information and solved my 6 month old problem. I do not know who he is, but I take my hat off to him..
My Check Engine light was continually coming on and I discovered that if I unscrewed the gas cap and then put it back on the warning light would turn off. I went to visit my family in Spring, Texas and I took it to an auto shop for an oil change before I was due to head back home to Montana. The mechanic told me the Check Engine light was on because there were THREE problems with my car...PROBLEM ONE-Serpentine Belt needed replaced (I got that replaced). PROBLEM TWO-Throttle Body Cleaning (I got that done too). And PROBLEM THREE-Needed EGR Replacement. I've had FIVE (5) mechanics tell me they didn't believe the Valve needed replaced. They all say that it sounded to them like it just needed to be cleaned, something about carbon buildup that need cleaned. I had to come home to Montana and my car is in Texas, so I have no idea what to do.
It won't start at times it happened not to long after the recall for the ignition switch. My turn signal lights have the same problem. They blink when they want and my car starts when it wants
My malibu is a 2005 but has the same problem with the ignition coil. My car has a bunch of recalls too.
Low pressure (90lbs) in cylinder 2 causing missfire. I have been the only owner and carried out regular maintenance. Out of warranty 8 months.
I have an idiot light "engine" and my diagnostic tool says cylinder 3 misfire. So I changed out the plugs and got the same cyl 3 misfire I cleared the codes and the light comes back on within a week.. all other modules and tests are fine. this is a highway runner 120 miles a day on turnpike. don't know my next step... it runs the highway fine and gets 33 MPg but when i hit a light when off the tpke at 700 rpm you can feel it running orugh. I have put like 6 injector treatments through it and half a can of carb and throttle body cleaner... snae light and message comes back... btw. this is a 2007 2.2 liter and it goes great and burns no oil and no rot... so I want to fix it and give it to the grand kid for graduation...but....
Felt Misfire after 4th gear, engine light came om. Pulled the code and its a bad coil in Cylinder 4... which is of course in the back of the engine :(
I have had this vehicle only a few months but it happens about every other time I start the car. I am also getting misreadings on whole system when I run a check.
