The car is a 1987 740 gle non turbo automatic, has new spark plugs, wires, cap and rotor, timing belt, and ignition timing is rock solid. Also has a new alternator and battery.
Alright so the issue I have been having is my volvo had been idling erratically and would misfire under constant rpm, but seemed to drive just fine for awhile. I had a similar issue at one time which turned out to be a small amount of corrosion on the #3 injector, and I have cleaned all electrical connections for the engine. (air mass meter connection, idle air controller, all injectors, distributor, coil, etc.) As well I cleaned the idle air motor out.
After I did all of this it seemed to idle perfectly at ~750 rpms, and then once in awhile it would again do the missing, and erratic idle and if I held it with no load at around 2k rpms and released the throttle it would die, and be difficult to start, and it would switch between running well and running like crap without hesitation, and vice versa.
So the other night I was driving and it had one of its fits, and the engine lost power and would barely chug along, so I parked the car and pulled my bicycle off the rack and rode home.
What I am wondering is if this sounds like a problem a failing air mass meter would cause, or potentially a bad connection for the fuel pump?
Thanks for any input,
