hello john here from Wisconsin this was hand me down Camaro with a lot of issues bad brakes which I replaced last year everything calipers rotors and pads now here the fun part its running but no power changed the camshaft sensor today running alittle better but it still shuts down random like at least 3 times yesterday at different times what should I check I know it needs
coil packs bout 5 yrs changed
plugs bout 3 to 4 yrs
wires 3 to 4 yrs
pcv valve 5 yrs
anything else I should check into still not running at full power any ideas will help

 

When it shuts off does it start right back up or do you have to wait? Also does the shutting off happen “any time” only when it hot, only when cold? Does the car have a fits (car runs normal then has a bad period where it shuts down and runs ruff, then all of a sudden it is running fine again).

Any codes?

If you can predicted when it is going to happen it helps a lot. When cars have random issues like this they can be one of the hardest things for a seasoned Master tech to track down. The problem is in many cases every part will past all the tests except while the failure is occurring. Most techs that work on these problem have a way to log PCM data on the test drive then come back to the shop and review what happen. Even then it can take some thinking and guessing depending on what happened.

After saying all that I would lean toward MAF and ignition module. A fuel filter and pressure test might be a good idea also.

 

when I start it it runs rough then smoothed out then random shut off driving in town its running a p300 codes which I know can be the plugs wires and coil packs but once its running it drives like a dream car but then random shut offs I just replaced the cam sensor yesterday but today still random shut off then wait bout 10 mins to 20 mins to restart then its fine it also yesterday it backfired and then shut off never had that happen before then 5 mins restart then it was good im goin to run codes again in a day or so at autozone and see if anything shows up

 

we getting tax money soon im changing the fuel filter plugs wires and coil packs and crank shaft sensor someone told me to change

 

might want to check crank sensor. my 99 3.8 m5 would start and run fine until i drove 7 miles then would act like it ran out of gas and wouldnt start until i let it sit for awhile.
