I 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 oxygen sensor or throttle
Position sensor etc.
I would like to norrow it down to a few things if possible thanks
