OK, i swapped out my old worn 4.3 out of my 86 for a fresher 4.3 out of an 88. I have had alot of proplems with the car not running right. I have adjusted the timing all over, replaced the distributor, module, coil, cap, rotor, wires, plugs and still cannot get it to run right. It runs strong at idol in park, but now as soon as i put it in gear, it dies. The only difference i can tell with the parts in the spark control module is different. The 86 and 88 use different part numbers. Other then that I am pretty sure the parts are interchangable. Can anybody give me anything else i can try.
Thanks
