Code 71 and 72?
I have a code 71 and 72 that will not go away. Replaced the whole ignition system with new parts, still pops up and car is still hesitating and miss firing. Please HELP
Could this be caused by a faulty O2 (I have no code for that)?
A faulty fuel pump?
Injectors? I have some to try tomorrow!
ONLY CODES BEING THROWN AR 71 and 72! I am stumped.

Re: Code 71 and 72?
are you 110% sure you have the correct firing order?
o2 sensor wouldnt cause misfires only lean or richness.
could also be your injector jumpers in the ecu. try a dif ecu
