This was running extremely lean peaking above 18:1 between 4-5krpm and the rest about 15:1. I need tuned but I have to figure out my problem before I tune it.






Ack your not running your car like that are you? You better drive it easy if you are, and hope you havent hurt anything yet!

As for what the problem could be, how long since you changed your fuel filter? Also, what kind of computer management are you running or are you running an FMU?

I know how it feels to lean out a SC car...it cost me my bottom end.




Cost me my bottom end to. Now I have a new fuel pump to put on as well as figure out what I'm going to do with the bottom end. Only thing it can be is the ecu next. Believe me I've done everything.
