My 1995 Suburban has a slight miss particularly at a braked stop but also in park. I have recently done a full tune up; plugs, wires distributor, rotor button, cleaned K&N airfilter, PCV, and fuel filter and still have the small falter. Tach indicates about a 100 to 200 RPM drop. No check engine light. Seem to run well. Nervous because I am about to drive from Alask to North Carolina pulling a light (2,00 lb) pop up camper and the family. Do not wish to get stuck in Cananda with broke 'burb.

Also outside air blows on my feet when AC / vent and heat is off.

Do a compression test on each cylinder, and check fuel pressure.

If equipped with port injection, test each injector with a noid light.

Also make sure all the grounds are clean and tight.

If everything above checks out I would replace ignition coil and pickup coil.
