08 Tuning Problem

KingCyclone · Post by **KingCyclone** » Wed Jul 30, 2008 2:14 am

I just installed the Predator in my 08 350. Worked great at first but now the engine seems to be starving for fuel in ALL tunes. What is worse when I re-install the original backup I get a check engine light(it does this in ALL tunes as well) and there is absolutely NO throttle response. You can put the pedal to the floor and the truck continues to idle. I have tried installing different tunes and then going back and still no luck. What is going on?

Can you read the diagnostics and tell me what the codes are when the check engine light is on?

Hi. The codes are P242C Unknown, P2291 Injector Control Pressure Too Low-Engine Cranking, and P1000 OBD System Readiness Test Not Completed

Have you tried clearing the codes to see if it cures the problem?

yes I have. several times. They all come back. Why would my stock tune not work? This tune can't be modified acidently can it? Why would I have NO throttle response?

Sounds like you have a bad EGT sensor. That will cause that.
