Having problems with your 1999 Ford Contour ?

I have a 99 ford contour, my check engine light came on and ran the code p0102 which is the MAF sensor. I replaced the MAF and my car still runs horrible (idles rough and wants to stall around 10% idle). can you help me fix it?

Answers :

Your new MAFS is not plug and play... you must clear all learnt data / fuel trim from ECU
\012Here is how:
\012Disconnect battery on + side, hold the + lead to earth (body, engine or chassis) this diffuses the system. Leave disconnected for 10 minutes, reconnect, start car and take on a 12 mile minimum drive (this is know as a drive cycle) pull over safely, switch off engine (new data now stores in ECU), start engine and happy motoring :o)
