Ok so I desperately need help... spent a ton guessing already and problem is still here......
1JZ-GTE stock
62-62 Driftmotion Single Turbo
PLX Wideband
Stock injectors
Walbro 255
Problem is that USUALLY the car goes rich, while driving or sometimes at idle.
When driving and trying to maintain speed it can sometimes go lean too. Usually around 25mph but it can vary.
There is a random idle surge for a few seconds where AFR goes from 14.7 to lean. This goes away after a 10 seconds or so.
What I've done so far:
Installed AEM v2 and got it tuned
Installed Aeromotive AFPR (currently set around 38psi)
New Spark plugs (may or may not be fouled from it running randomly rich) BRK7
New Coil Packs
New Coil Pack Clips
My thoughts:
Possible injector clips being too loose, will replace next
Fuel pump acting up? Doubtful but possible
Sticky injectors
please help me out... already spent a lot trying to fix it.
