Hi, I have a question for you. The engine light came on, I plugged in the code reader and reset the light, everything seems fine. The code was P1197 "02 sensor slow". What dose that mean and what do I need to do about it?
Thanks.

 

It's gunna be a downstream O2 issue. Might just be an issue that requires the sensor to be replaced, though a diagnositic procedure is defined for this situation. I'd try unpluging both the rear sensors, putting some electrical connector grease in them and reconnecting them.

 

That's great, thanks.

 

just for my own notes, what year and engine do you have?

 

Mine is registered as a 99, 5.9ltr V8, Procharger P1SC, intercooler, methanol injection system, Aeromotive FMU.
It's a single cab, blue like your pic but with silver SuperBee stripes down the back end.
I was told it is capable of 800bhp with boost at 30psi and meth at 60%.
I have a dyno print out for 530hp boost at 15psi meth at 30%.
It has done the 1/4 mile in 11.24
It is running at around 6psi now and I dont know how to wake it up.
