It is extremely easy to get the plug wires placed on wrong coil terminals - that will certainly cause the symptoms you have posted here..

Google > 3.1 gm firing order

That'll show you where the plug wires go for the 3.1 OR the 3.4 engine.

I highly recommend re-checking firing order..

Good luck!

I see this is a 1986 year model - for that we need to know WHICH ENGINE is under hood.

Disregard previous answer.
