Hey everyone first post. Tried using Jeepforum.com but figured two sites are better than one.
Backstory: Bought a Jeep while I was deployed. Jeep was in Alaska had my parents go check it out and had no big issues. Belt needed to be changed and few rust holes. Parents drove around for a few weeks. Had it shipped to Hawaii. Picked it up and as soon as I started it engine code and jumping idle / boggy engine.
What I've Done: Had the code ran with a misfire on 1. Replaced spark plugs and cables gaped at .035. Put some SeaFoam in the engine and sprayed the intake out. Didn't help.
Next I changed out the fuel injectors. Reset the computer and problems got worse. Old fuel injectors were shot so stuck for now. Changed out TPS, Coil, MAP, Dis cap and rotor. Cleaned up all the connections I could find. This is where I'm at now.
Problems as of now: Idle is horrible. Starts at 1k drops down and bounces between 500 and 700 then up to 1000 and back down etc etc. Get the RPMs up to around 3k and let go it backfires and sticks at 1250 to 1500 RPMs until I turn it off and restart. It has almost no throttle response when driving and the transmission is shifting harder than it did when I first picked it up. The CEL is still on but wasn't able to have it ran because apparently Hawaii thinks the holidays last for a week or so longer than the rest of the U.S.
Anyone that can give me some insight on where to go next would be great. I'm going to have the codes ran again tomorrow and will post an update. Thanks again.
