Hey guys I have another topic on here but found new problem. Truck will start and idle rough and heavy fuel smell in the exhaust. I wasn't getting a code on my outlook so I unplugged it and plugged in a handheld code reader and got codes p0121, coc95, and c0900. I know code p0121 is throttle position sensor but don't know what the other two are. Would the throttle position sensor cause my symptoms. I have done a volt test on the FICM
and all three test were 48 volts. I cleaned my turbo and replaced fuel filters.
Here is all what I have done to the truck with in the last year and half
powermax turbo, arp head studs, black onyx head gaskets, oil cooler, egr
delete, blue spring upgrade in fuel regulator, coolant filtration system, custom ccv
mod. Within the last two weeks #1 injector, new HPOP
About 2 years ago BULLET PROOF FICM
I am running a Bully Dog programmer with Outlook and straight exhaust after the cat
. Truck was running great and getting 18.2 mpg
then all the sudden this problem. I have tested everything that I can and cannot get the p0121 code to delete could this be the culprit to all my problems.
