So ive read tons of threads and haven't gotten really any where.
Story time!! I have a sc300 bought a 1jzgte r154 ecu and harness threw it at the car
Re calibrated tps bought a 2jzgte map new plugs water pump main seals timing belt clutch ect
Motor is stock just fmic and down pipe straight pipe
Problem time
So cruzin at low speed a/f is at 13 but at wot it richins to 10, boost at wot is 13 psi. if I'm at high way speed cruzin a/f is at 10. The car at idle, surges from like 800 to 1500 while it does that the a/f goes from 13 to 20.
Can't find a vacuum/boost leak killed a couple cans of brake clean on it. Thought it might be the stock fpr but I doubt it. Cleaned the iacv. Opened up my ecu it looks brand new but I couldn't get it to light up the cel so idk what codes it has. What do y'all think it could be?
