Ok well about two month ago the check engine light came on in my 95 GSR when i put my random tech highflow cat on. I figured it was just from the O2 sensor in the cat
i just checked the engine code and it's throwing a 3 and 5, according to the manual for the OBDI ecu it's saying MAP sensor.
How serious is this and what exactly does it mean? Should i not be driving my car?
It runs fine, no lack in power at all.
