Oh yeah, I did try to move the MAF harness around but did not notice any changes in the idle. The engine probably did not run long enough to know for sure, though. I will definitely try all of these other suggestions!Blake you didn’t confirm what you observed when the motor is idling and you move the maf harness around. Same deal with the injector harness. If no change in idle rpm or quality, did you replace every inch of vacuum hose? If not you know what to do. Could be a tear in the turbo inlet hose so look there. Spray carb cleaner in suspect areas with it idling. Idle increase gives you clues where to look further. Does it idle smoothly and evenly? Check the exhaust tip for this. Is the hood shaking or is it rock solid with the thing idling? That’ll offer signs of poorly firing cylinders. Does the idle hunt or is it just steady but high? Put up a video. Prob get more help. Resetting the ecu is another option and how does it behave thereafter? Check the quality and tone of the injector pulse by using a long screwdriver up against each injector’s base and listen to the handle in your ear. Good for now? I’ll read your whole thread since admittedly I just jumped in. I’d do all of this before buying a jy maf.
i did replace them, but to be honest i don't remember what sizes they were - i just took the check valve pieces into the auto parts store and tried every hose til i found the correct size. kind of interesting, the nipples on each side of the valve were different sizes and required different hoses. i'll look again to see if they size is on my receipt or the tubing itself.Curious if you replaced these hoses and if so, what is the size?
