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.
 
Just change all fluids to synthetic! I got 320XXXkm.on my 85 740T an it
moves fine at -42c except for the tires they stay flat for a while 200
meters or soo ....you should see the exaust plume in second gear with full
boost.....i must post a pic !

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.....
