NEED HELP WITH DIAGNOSTIC ON 2000 GT!!
 

hello everyone, ive got a 2000 GT with a Saleen supercharger. the service engine light recently came on. ive had the codes pulled (P0174 and P0171) running lean on bank one and two. ive checked for vacum leaks, replaced fuel filter, replaced air filter, cleaned mass air sensor, checked PCV valve. also its idling rough, it goes from about 600RPM to approx 1400RPM. however only does this when its warmed up. if anyone has had this problem or would suggest what to do that would be great. appreciate any useful information. thank you!

try the IAC?

how long has the blower been on the car and has there been problems before? did you get a dyno tune when the blower was on? what fuel injectors and fuel pump are you running?

no i havent messed with the IAC yet. the SC has about 5k miles. its got 32lbs injectors from saleen that came with the kit. not sure on the fuel pump. the computer was reflashed by saleen but it hasnt been on the dyno with the SC.
