I have noticed a couple of discussions on this very topic that show no final resolution.
I recently bought this vehicle in a non-running condition - it set for 3 or 4 months without running. I quickly found that it had no spark. After extensive troubleshooting and a couple trips to the parts store - i found that the Ignition Pickup was bad. I had already replaced the Distributor control module and coil - new distributor cap, rotor, and plug wires. I traced all the wires in the control module curcuit and in the process inspected most of the wiring on the vehicle - most looks decent for an '86 - but all that I tested had good continuity.
I drove it to work on Monday of this week for its maiden voyage - I drove it to downtown KC (30 min drive). Runs great down the highway - but after getting downtown - I when to drive it up into a parking garage and it acted as if it had no power - sputtering, rough and eratic idle. I finally got it parked and it set for 3 hours and ran fine for the next 30 mins of driving. The same events were repeated twice again that day after about a 30 min drive each. The last time that it happened it finally died and would not start until it again cooled down.
I babied it to Orielly and pulled the codes with their handheld. Codes 32, 33, 34, and 25. I think that it was slightly out of time - which may cause the 25 code-Knock sensor, but 32 33, and 34 all deal with the EGR, EVP or ECA(which I am not sure what the ECA is?)
Found one forum suggesting maybe the temp sensor for the computer. I replaced this, but no change. Took of the EGR and cleaned up, but no change. Last night I noticed if it started sputtering I could disconnnect the vaccum line from the EVP to EGR and it would run a little better.
Any suggestions as to where my problem may be. Thanks,
