Hi everyone, so i've came across this problem when i'm driving starting acceleration is fine it gets up and go's but after about 30 it want to hesitate and bogg down when i'm giving it gas. Would like any suggestions or idea's of what might be going on?

Thanks,
Adam

 

check to see if your intake manifold bolts are tight. also check inside your throttle body for gunk. take out the tps and iac and clean it all up.

 

Ok sounds like a good place to start, Thanks gonna try that out and will post what happens.

 

Well i just bought the xj a few days ago, coming from a zj so i appriciate the help well i looked at the throttle body and it is just filthy ive never seen one this bad,lol think i should do a full tune up and clean the throttle body and tps and iac whats the best way to clean the tps never cleaned on usually replace it.

 

TPS cannot really be cleaned. If symptoms/testing point to it, replace it.

But start with a thorough cleaning of that throttle body, idle air control, perform a FULL tuneup including fuel filter and see where you're at after that!

 

check the connection, The plastic line was broke on mine and it run like crap.
