I pulled the jeep out of the garage today and it has a slight miss at any rpm (1500, 3000, 5000). The rpm drops about 200-300 and jumps back up.

I've checked fuel pressure and i did not find any vac leaks.

I did a quick search.

Any help?

 

in my tpi camaro i was having a slight miss and decided to check my cap and rotor and found that my cap had alot of corrosion in it. i cleaned it up with some sand paper and also replaced my spark plug and it now idles great and i barely even notice any miss if there is any. Also get some techron fuel injector cleaner and run that thru your car on a full tank of gas and dont fill up till your almost about empty and that will help as well
