Thanks

Thanks guys. I'll go for the injector cleaner and leave them alone if at all possible. I've got some decent oil leaks in a couple places around the valve cover, and the nub that holds the PCV valve into the back of the driver's side valve cover is stripped (had to glue the PCV in in with RTV to...

Truck has ~160k miles and I'm going to do some more towing this summer, so I'm doing a pretty thorough service with timing chain tensioners, water pump, thermostat and housing, valve cover and intake manifold gaskets, etc. Should I replace fuel injectors or leave them alone? Engine runs well...

Hey I think that worked! Replaced the TPS and cleaned the MAF after work. Initially no change but after a cross town drive it seems the ECU adjusted parameters and it's running normal. Fingers crossed it holds. Thanks!

Been awhile since I was on this forum, but looking for some diagnostic help. My 4.0 has developed an idle problem, which I assumed to be a vacuum leak as it's had a few of those in the past. But the carb cleaner/propane test doesn't bump up the rpms and if I disconnect the IAC it dies...

Hello, Just upgraded my clapped out '02 2wd 2.3L Ranger to an '02 4wd 4.0L Ranger with 110xxx miles. The one I picked up has both the offroad package and the tow package- it's got the torsion bar front suspension, there's no rear sway bar, and the shocks are stock Motorcraft. I'm not an...
