Greetings,
Still having some RPM "hunting" when cold start. ( to the point of stalling) So far I have:
Installed New Delphi Fuel pump and Ford Motorcraft Filter (due to low fuel pressure)
Installed New Motorcraft IAC
Installed New Motorcraft TPS - Checked for codes (had a 121) TPS low voltage. When warmed up I get 0.76 Volts and then smooth through to WOT 4.2 volts. (After changing he TPS.)
Removed and cleaned MAF - inspected TB and butterfly - TB seemed clean.
I ran probed the MAF Blue wire and ran signal voltage at idle and got .52-.64. Increase speed to 20 mph erratic readings between .09 and 1.2 volts.
Did I miss anything?
Thanks
