Ok, I have been working on DSMs for long time now so I have ran into so many problems before besides this one. Well, my brother has a 92 awd talon with:
Rebuild 6 bolt block with 8.8:1 venola forged pistons
1g big rods
Stock crank
Balance shafts removed
Stock head (rebuild)
Arps head studs
Felpro head gasket
272 web cams
PTE 50 trim turbo
3 inch exhaust
Sbr exhaust manifold w/ 38mm waste gate turbonetics
Fmic
Greddy type s
Egr block off
Lower half of throttle body block off
Greddy catch can
Ecmlink v3
2g maf
Extrude honed intake manifold
6 bolt intake heat barrier from magnus
Denso 660s injectors
255 walbro
AEM wide band
So here is the problem, the car for what ever reason runs good on a cold start then once
the engine gets hot now starts running pig rich all the way to 10 on the wideband. I did a boost leak test and fix small leaks but currently no leaks what so ever! Brought the fuel pressure down to 28psi and nothing. Swap injectors to 450s, nothing. Made sure base timing was set with timing light, set! Make sure TPS was set correct,set! Double checked my wiring for the 2g maf, check good. Make sure turbo is working, check working good. Stock oxygen sensor is work great, (brand new). So idk I don't get it! What is telling the ECU to run rich?
Any thoughts or suggestions will help me out greatly.
