Getting similar CEL's myself.
This is a discussion on Having problems, I'm getting a lot of error codes within the General Maintenance, Troubleshooting & Accidents. forums, part of the Tech & Modifying & General Repairs category; Hello I'm new to this website and I'm glad I found it since it seems a lot of you could ...
I'm new to this website and I'm glad I found it since it seems a lot of you could be able to help me out with this.
Here is the story:
I had to replace the "head gasket" (not sure about the translation but it's the gasket between the motor head and the base of the motor...) and I ported the head and rebuilt the seat valve, with this I changed all the pulleys, timing belt, timing belt tensor, all the straps, cover valve gasket, spark plugs, etc...
I have an up pipe, down pipe, cobb's SS 3" exhaust cat back, intake.
When I plugged the AP in the ECU it told me that the voltage of my battery was too high, about 0.015 volt too high. I figured it's not that of a big deal.
I loaded the stage 1 v300 91 octane program from the accessport.
Everything seem to run well. Only my idle was a little bit low but still it was running fine.
I drove about 5 or 6 miles and the service engine soon light lighten up.
It gave me these codes
PO171 : too lean
PO420 : Catalyst System Efficiency Below Threshold (Bank 1) ( I don't have a catalyst anymore) the exhaust is straight pipe
PO304 : cyl4 misfire
PO303 : cyl3 misfire
PO302 : cyl2 misfire
PO301 : cyl1 misfire
PFFFE : which I couldn't find what's this code is about
And now the car isn't going to it's full potential. It has some kind of a lag. The explosion don't seem to be at a constant rate.
I'm not really an expert with car's mechanic, even if I am an airplane mechanic (airplan don't have ECUs or electronical injectors and what not, everything is mechanical... carburators, magnetos, etc. Or it runs with turbines. I guess I would not have any problem if I had an old car from the early 70s hehehe)
I was wondering if anyone could help me out with these codes and give me a heads up with what I should do to fix those problems?

What model year is your car?
Regardless, you have an aftermarket downpipe, you should be running stage 2. Stage 1 requires a stock downpipe.
Pray you didn't melt a piston or anything hopefully you've kept it out of boost since then. Yep, modern day systems are awesomely finicky =l
