Greetings;
I recently purchased an 87 delta 88 with 41000 acutal miles. All systems were serviced as you would do after a prolonged storage including an injector flush. The plugs, wires, etc were all changed.
The vehicle performes well but has an iritating missfire/vibration at idle. It is not serious, but can be felt in the steering wheel as if one cylinder is down on compression, but its not. It performs very well in all driving ranges and starts well. Any suggestions?
Thanks in advance.

Look for a vacuum leak. Clean the throttle plate from the back side.
