missfire when engine cold
Last spring my 3.8 N/A t-bird would'nt start. I changed the cap & rotor plugs and plug wires. It would start but it still ran a bit rough when it was cold. I then changed the fuel filter - made no difference.
I went fishing with my girlfriend parked the car and then when we were done, started the car and the revs went all the way up to 2500rpm. Changed the IAC and that fixed that trouble but still a running rough when cold.
Bought a code reader for the car and I was getting a code 332 - so I changed the DPFE sensor and that got rid of my code 332 but the car is still running rough or missfiring when cold.
Any other ideas what to test?
I was going to clean the MAF tommorow and check the fuel pressure. I'm going to pull all the spark plugs also and re-check them. I was also going to do a compression check on all the cylinders.
Can the coil packs on the these cars cause this? Should I be getting codes for the missfire?
