I have noticed sluggish acceleration with my jeep cherokee sport lately (6 cyl. 4.0L). It happens especially when the engine is warm and when trying to push the engine to get on the highway. It also makes a kind of garggling sound when I push the gas. I have tried fuel injector cleaner but it did not help. Any suggestions? Thanks

 

maybe some new plugs?

 

Just replaced those about 3 months ago.

 

pour seaform directly intop Throttle body like it says to do on the can.

 

you could have a bad exhaust leak, it makes the jeep sound horrible if its bad enough.

 

fuel filter?

 

check your coils too

 

injectors?? clogged maybe. or btwn cylinder head leak. my sisters mustang had one of those and it ran like crap
