    No stalling no drivability issues besides lean codes. I’m changing out harnesses either way. Injectors are all firing and the car isn’t missing. I’d rather have the peace of mind and eliminate a potential electrical issue by having all of the correct harnesses.

    So it turns out the car has a GT dash harness….. hoping this might be causing the issues any ideas? Looks like whoever I bought the dash harness and the ECU harness from went to head and changed a pigtail so it would plug-in but I know there’s other differences in the dash harness from what I’ve...

    So got my car back from my friend after going through the system with no luck. I found that my DPFE hoses are reversed. Not sure that might be throwing the whole thing off and causing an EGR malfunction. If I post some data log information can someone help me out?

    Yeah we’ve swapped the mass airflow meter the car has all brand new O2 sensors on it. The JLT intake came with a carb sticker so the ref said that’s fine. The car has been smoke tested and found nothing but a leaky EGR valve that was replaced. Even to make sure we still pull the blower and...

    yes only codes showing. Only mods on the car is JLT and blower is ported with stock pulley. Not sure if the blower is the issue but I’m not spinning it faster… wouldn’t think that would cause a lean condition. Maybe I’ll talk with a tuner.

    It’s the JLT that uses the factory maf and housing. You thing that would also cause short terms and long terms to peg?

    The car has been smoke tested and propane’s. PCV system is pretty much new. Mid pipe was just off to change out all the O2’s. Now mani or midlife leaks. The car is running stock injectors and a stock cobra mass airflow meter. The tune in the vehicle is the factory Ford tune it is not tuned. I...

    Running to bass factory for tune on it since it’s also running the stock size pulley on the car. Trying to get the swap legalized here in California so I have to have a stock pulley on it for inspection

    So the blower is spinning stock boost levels but it’s ported. I have a JLT cold air intake but that’s it. The car is running on the base factory Ford tune.

    it was changed. Still having codes. Blower was pulled, new intake gasket blower gasket, egr new, lower tube under blower changed. My buddy is running out of options. I’m starting to think the ecu I bought second hand is a dud or corrupted somehow.
