Hi All:
Have a fussy '88 740T. It starts no problem. But don't even think of trying to move her until she is really warm. The hesitiation comes in all rev ranges, gears, load/no load etc. Feel like a cylinder(s) cutting out. Being a novice on these Volvos, not sure where to start...especially when it's -25c without the windchill outside ;-)
Cheers, Andy
Has the engine wiring harness ever been replaced? Coolant temp sensor for the injection might be bad or have a bad connection.
He's obviously got a problem of some sort, synthetic isn't gonna fix it.
Actually, it's always had synthetic. But thanks for the idea James, I will get under her hood as soon as the snow stops and the wind doesn't threaten to tear the hood off. It hasn't had its harness replaced that I know of, but the current one appears to be in better shape than many I have seen. Realizing looks are deceiving, I will check out replacing it.....
Cheers, Andy
