Hey guys, got a problem I been working on for about 6 months now, and I've done alot of research so far on what possibly can cause my SR20DET to run Rich, but I still cant seem to find out what exactly it is. I'll post everythign ive done to try and correct this issue.

--I've bought all new Chassis harness for the car- the correct harnesses for the car

-- had the Engine harness professionally spliced and wiring for the conversion

--replaced spark plugs with new ones

--changed out the Ivac and throttle body sensor

-- MAF should be good, but i dont have the money right now to buy a new one to see if thast the problem.

--Changed out the stock FPR with another stock FPR.

-- Cleaned out the stock injectors and made sure they are not leaking or dripping, they are spraying perfectly

So I was wondering, what else am i missing to check to see what might cause my car to run super Rich. Also, if maybe anyone else who hasever has this similar issue, maybe there was a trick you did and it worked, i dont know, any feed back on what t do would be great! Im getting tired of bumming rides hehe =/

thanks guys.

check ECU for Codes

Check all Vac lines and IC couplers for leaks
