HELP! Severe acceleration lag

juld0zer · 07-20-2014, 06:51 PM

the crank angle sensor is very annoying to get to. i have small hands and at this rate i will be referred to a psychiatrist from all the scratches and cuts on the back of my hands! there's not much room to work in.

cam sensors are really easy - at the front of the engine. you can do the checks without removal but the engine should be cold because the service manual specifies @ 25*c

Yeah, that crank sensor is a Bee0tch to get to. I can't imagine removing it w/the OEM cats installed.

Did you reflash the ECU back to the OEM ROM and see if the problem persists

still running the tuned throttle tables. i dont think uprev is the cause because the problem only seems to appear when the engine gets up to operating temp. it's still a variable which i will explore when i get my car back.
