1997 Pontiac Sunfire Repair Question
Pontiac Sunfire Engine Problem
Asked by lynnkathleenAnswer
You need to start out by having the computer codes read and post the code numbers here.
Thank you....we have to find someone to read the codes. And then it will be possible to give a diagnosis of some kind??
Most nationally recognized parts stores will scan the computer for free. If there is an Auto Zone, Advance auto... near, contact them.
We went to Advance and the only code was PO300...which the guy said was meant the car was just misfiring, that's all. Thanks for your help. I wish we could narrow it down.
Yes, that does leave a lot of unknown things. Random misfire can be caused by any number of things.
What engine does this have?
OK, that's what i suspected/ This engine has a very common problem. The whit coil housing cracks internally causing misfiring. Make sure the plugs are in good shape and have no cracks in the porcelain, then I would replace the coil housing. It cost about $40.
It's #7 in the picture
Thank you..... is that also the reason for the other problems because a friend of ours said it was the coil also and I don't trust that guy.. lol, but thank you!
Also, how difficult is this to install? My boyfriend is blind but with an extra set of eyes he has built and dropped a few engines in his Nova, installed the starter, and other things...Thanks again
