Want to find out if anyone change extractor 421 experience CEL problem for MAzda 3 auto- can share or how to prevent CEL as this is the common problem. i am thinking of changing as i do not wan to spend time solving the CEL.
I just installed an evo 3 spring + absorber (front and back) but the half cut shop gave me a wrong combination. The front is now around 6 1/2 fingers height and the back is only 2 fingers. Would there be any problems...
