1991 Legacy Wagon Idle/Surge Problem - especially in gear
Posted 16 June 2004 - 09:17 PM
Pulled all the plugs again, they look fine and are gapped correctly. All the wires seem fine, and pulling any given one seems to decrease the performance of the engine more or less evenly between all 4. I can't find any problems with the vacuum line system (no obvious disconnected hoses, cracked hoses, etc.). I do note, however, that the exhaust smells strongly of gasoline vapor, as if the combustion chamber is too enriched (too much throttle?) - it is noticable even up even by the driver side door.
I have not had any check engine lights, nor has the car had any history of overheating, etc.
Any suggestions on things to look for?

I have a similar issue now and do not have a CEL. I am hoping it is the ignition coil. I think your rich smelling exhaust may be because the cylinder is not firing and just dumping a cylinder of raw fuel into the exhaust.
I think the surge (does it lurch forward when stopped because of a burst of power and you need to apply the brake more?) is from the car not firing on all cylinders all the time and then firing thus giving more power and lurching.
