Specs:
1jz
Blitz ecu
Sard 620cc
SAFC II
Problem:
Car was done 3 weeks ago, and Dyno tuned Last week. everything was 100% perfect. but had a weird oil pan leak. we drained the oil, removed the pan, and resealed it. added fresh oil. then cranked it up. then all of a sudden the car was dumping fuel bad, and would stall. it now does this everyday until the car is completely warm then the problem seems to go away.
Parts that were replaced over the next few days:
IACV
MAP sensor
Coolant temp sensor
TPS reads fine on the safc so its not TPS. every sensor including Air temp was tested. Opened up the ECU. no leaky caps or discoloration anywhere.
When cold the car runs so rich that it fouls out the spark plugs and you can smell gas in the oil. if you try to drive like this the car bucks badly and will die every time you come to a stop once warmed up the problem eventually goes away. what is causing the car to run super rich and die when cold?
