Thread: Serious problem codes and freeze frame

Hey everyone lately my 03 GTP has been chugging at idle ( drops from like 900 rmp to 700 rmp) it has lost power and feels like it is dieing or atleast i feel like dieing right now. been noticing a slight sent of gas too, ive already replaced vaccuum lines and inspected what i can see of the gas lines for leaks ect any ideas what could be causing this evil error?
a few side notes im running a 02 simulator on the sensor 1 bank 2 and i have no egr or cat.




p0134- 02 sensor bank1 no activity detected
0403 egr control circuit
0405 egr sensor a circuit low
p1571 invalid trac control signal detected


Fuel system 1 status OL-Fault
Calculated load val 0.00

thank you for posting codes and FF
anyways dont you have the pcm tuned for the no egr and cat?

put that mesh screen back in.

Sounds like you need a tune bad aswell, that should help rid all the egr and cat codes.

its not tuned, would getting an overkill tune make it stop bogging? or just hide those codes?

it would help all together,,the codes are making it run bad

get a tune man, running a 3.4 pulley on the stock fuel tables is just asking for trouble.

Along with a bunch of other things. The tune can delete those codes and help your car out big time.

ok cool so just getting a tuned pcm from overkill? or do you mean getting a dyno? because thats gonna be hard here..

contact overkill with your mods and ask him about his tunes and he should be able to help you out.

sent him an email

Check all your fuses. That looks like one of the fuses that controls all the stuff above blew.

Awesome job on listing out the codes and info. Thank you very much.

P0134 is no activity on bank 1 sensor 1. That's the front aka upstream O2 that reads all the engines activity and allows the pcm to control fueling. I'd check that sensor and replace it.

Fuel system 1 status OL-Fault: This means the system is faulted to open loop running, which by default is meant to run the car on the rich side.

It would help if you got a pcm that was tuned for the EGR being deleted. Also it would help if you tracked down which part of the traction control system was bad

Get rid of the rear o2 sim and put a sensor back in there...Mr. 01+ car guy.

also seeing the MAP at 102 KPa that means there is no engine vac.... so the freeze frame is either when the car had not started or the MAP sensor is not seeing any vacuum.
