1985 Buick Electra

Engine Mechanical problem
1985 Buick Electra 6 cyl Front Wheel Drive Automatic 243000 miles

I change the ignition module, rotor, dist cap, egr valve, egr vacuum solenoid, plugs and wires. The car keeps on shutting off what am I'm missing to do also getting code 34 which according to the code book it means map sensor. I bought the egr vacuum solenoid which included the 4 pin connector map on it together with the switch and a round like cylinder behind it and wired all together with switch and I guess map sensor and switch. So want would be my next move.

Thanks Harry

Suspect the pickup coil around the distributor shaft. If your distributor has a vacuum advance unit on the side, sometimes you can make the problem occur by applying or removing vacuum to it. That makes the mounting plate move and flexes the wires which could be broken. This is not a definite test.
