It is a little tricky to put back, please be patient, it is not that bad: you have to turn its shaft to match the camshaft, don't force it in. |
good idea. but remember to make paint marks on the sensor and on the engine so you line it up the same as the way you took it off..... you don't want to mess up your base timing by lining it up wrong.

when the maf is unplugged, it will not rev past 2500. that's normal.
