cherokee running funny
 

one of my cherokees just recently encountered this problem. When you first start it it runs real rough almost like its missing... but when you give it gas and start driveing it will start to act normal. And it does not always do this. Any thoughts?

its a 2000 by the way... bone stock, 4.0

Hmm.... Not alot info.

Check and/or replace the spark plugs.

Good Luck

if you dont know the tune-up history on the jeep i would go one step further and do cap/rotor and wires with plugs. moisture really affects those peices.

check your fuel injectors for leaks also, if one is leaking do not start or drive it until replaced.

not into a car-b-que huh. ill bring the burgers :eek:

yea not sure of tune up so im replacing wires and stuff tommorrow... no injector leaks... was thinking maybe a tps sensor or air sensor too tho

Mine did the same thing not long ago. I put some fuel injection cleaner gas additive in it and changes the plugs, wires and distributor cap. Ran fine ever since
