Just for kicks, I changed out the old genuine LR MAF sensor for the new Britpart
one that was recommended earlier in this thread as I already bought it.
Idle now is lower in the 500 range, much rougher and needs the gas to be pressed to keep it from dying and the CEL is now on. Does the new MAF need to "learn" or is this a defective one? Later today, I'll reinstall the LR MAF.
