CEL !!! it came out from no where.!
1. Oil preasure at 3 rpm is 48 to 50? is that right?
2. i got a race pipe, and i just got my catback installed last night. then CEL came out this morning.
anyone could tell me what's going on.. (and i got a MazdaSpeed CAI)
PLEASE HEELP
The quickest way to eliminate and verify if the CEL is really the problem, I would suggest you to disconnect the negative for 2 to 5mins. and Put it back on. If CEL still comes out then you can proceed to next other troubleshoot. It might be sometimes the ECU got confused on the new mods.
