I am new to this club and I need help. My service engine soon light is on and I don't know why. I have replaced the fuel filter/air filter and it is still on.
I recently installed a six position box from Zelectronics and an MBRP 4" system. I towed a trailer to Texas and back with no issues. The light came on on the way back.
The truck stalls occasionally until its hot. I turn the tuner box off and wait till its hot before I turn it back on.
I plan on replacing my turbo wheel with an aftermarket wheel soon and I want to fix this service engine light issue at the same time.
