i know i will probably get screamed at to use the search but i did and didnt see anything. i am looking to sell my car and it has a greddy kit on it. right now i cant sell it because the check engine light is on. it is throwing 4 codes:
misfire on the 2nd cylinder
catalitic converter not operating at a good temp
Primary O2 sensor low voltage
running too rich.

i cant find the print out or i would put it exactly like the paper said. i need to fix these problems if possible. if not, i guess i will have to pull the greddy from my car which will be expensive. I talk with Mark at turbo tunes here in greensboro and he said that the misfire could be caused by plugs or plug wires. i have changed the plugs very recently so i doubt it would be that. one of the techs from mazda said it is probably all caused by the O2 and that there isnt a damn thing i can do about except take the turbo off. Has anyone been able to fix these problems? Any help would be appreciated.

 

did you ever tune your car?

 

yep. took it to get tuned at turbo tune here. there was something wrong with it because at around 4-5k rpm the engine would fluctuate and act like it was going around 14krpm.

 

thanks for all the help guys..... no really!

 

sounds like the same problem i had when i put my race pipe on how i fixed it was i spaced out my secondary o2 sensor with what they call a spark plug anti fouler u can get them at any auto parts store

 

i hate when turbos are greedy

 

ya damn skippy
