4.0 power loss


Thanks guys. I will try all the above.
 
Appreciate the tip aabout the bed though. I've a got a leak in the refueling line where it joins the tank. Hopefully I can access it this way. Kudos.
 
get some Mass air flow senser cleaner and clean the maf. I had some what of the same problem with my 4.0 and that fixed it haven't had another problem.

lol, isn't awesome to top out at 50? I used to have even big rigs passing me. Anyways my problem was a dirty MAF. The fix I found off this website, said it's a common problem with the 4.0 engines and that you should probably be cleaning it out every 60,000.

Good info guys, I disconnected the MAF sensor and it really came alive so ill try cleaning it as soon as i can. Having a 19 y/o daughter driving it, it isnt home much for me to tinker with. Any long term affects of running with it disconnected?
