Does anybody know the proper way to test the coil packs on a 95 max. Mine is having a driveability issue it's down on power. It doesn't seem to miss but it is doing that kind of vibration when I roll up to a lite... then it idles fine however the tach is right on idle wise in this situation. No indications of any other problems the plugs and complete tune up are about 20,000miles old. This car has about 205,000mi. I did clean the throttle body 2 years ago but I did not clean the iacv. Let me know what you guys think thanks.

 

I'd say it's time to clean that TB again, and do the IACV while you're @ it (with new gaskets of course). Also replace your FUEL & AIR filter if you haven't already done so.
