Engine is choking when shift in gear 700 1986

posted by  someone claiming to be Tike on  Fri Jun 21 09:37 CST 2002 [RELATED]

Three weeks ago I bought used 1986 Volvo 740GLE with 135,000 miles on it and I liked the car from the first day. It showed a couple minor glitches that I planed to resolve step by step. Till now I did not have success.

A) At 750 RPM idle seems to be a little rough, uneven, and engine jerks sporadically

B) A warm day. When I start the car and immediately shift from park to reverse or forward, the car chokes, shakes and cut off by itself. Sometimes if I release brake quickly and make it rolls, it will be stalling for a second but will not cut off. If I give it 30-45 seconds to worm up it will be OK although I can still fill a little bit of choking when engage gear. Once it starts moving it is fine.
It does not seem to have this problem if engine is warm.

C) The acceleration is sluggish.

Sparkplug wires seem to be fairly new and I replaced sparkplugs, fuel filter, distributor cap and rotor and adjusted ignition timing to 12 degrees using light gun (before it was showing 15 degrees). Also I tried another, used, ignition coil for testing purpose.
No improvement showed.
Please help with suggestions.
