The '2 is back to stock and now it won't idle when it's cold it just drops revs and dies. It runs fine when it's warm or if i put a bit of throttle.
Now it started while the e manage was still on controlling the larger injectors, but now the stock injectors are back in and the emanage is off. So i know it's not injectors, or ECU wiring. I've cleaned the MAF, put my WB O2 back in and used it's output into the ECU so i know it isn't an O2 problem. So the usual suspects aren't the problem.
Ideas anyone?
You may have a faulty MAF sensor
