and now my xj wont start. i pulled off the intake hose off and sprayed some carb and TB cleaner in there and wiped it all down, because i didnt have a torx bit large enough to pull the whole TB off. so it wont start now and i can't figure out why, anyone have any ideas?

 

Did you disconnect any sensors in the process? What does it do when you try to start it?

 

i didnt disconnect any sensors and when i crank it it just cranks like normal, but if i put my foot to the floor it starts up and will run at like 5k RPMs then die in 3 seconds

 

Is your tb stuck at wot?

 

i know your not supposed to use carb cleaner anymore... only TB cleaner... i was unaware of this when i did mine and used carb. it didnt do any damage. BUT. when i did mine, i pulled off the the TB and disco'd the TPS and IAC. applied a lot of cleaner and then spent quite a while getting all the remaining cleaner out of the crevasses by getting to it from different angles. it sounds like you sorta went the quick route and just sprayed and wiped... idk for sure, but i have this feeling like your IAC or TPS is clogged with (dirty) cleaner... i dont think it takes much to mess with those sensors, so it might be worth pullin it all apart... my .02
