bytesnooper -> 92 ford aerostar (6/13/2005 6:32:39 AM)
|
have a 1992 3.0 aerostar. 90k miles. Was running great until about two months ago. When in the morning I would start it an it would surge from stalling to idle. If I accelerated for 10 seconds it would run fine the rest of the day. Last Sunday I started it
It stalled out and wouldn’t start. It starts now but the engine runs really
Rich. Black smoke out the exhaust. Does anyone know if there is a common?
Problem like this out there, that usually turns out to be the some switch.
I changed the oxygen sensor, throttle position, fuel reg value. When I start it cold
runs not bad for a minute or so then starts with the rich mixture. running out of things to
replace.
I would like to narrow it down to a few things if possible anyone have any Idea
Its a good van but has a senor or something screwing things up.
thanks
