I just bought a 05 Jeep GC hemi, Its very clean looks and car fax seems to be a good deal, but it did have some codes. first off, I'm new to the hemi, i got this code p0507, so i removed the air intake(all stock) and the TB and just used a tooth brush and lightly scrubbed it and wiped all the carbon i could away.. disconnected battery and engine light came back on 30 miles later... So i repeated it but this time took the TB fully off the jeep and sprayed the cleaner just on the butterfly(both sides) looks very clean, reinstalled it, engine light came back on bout 30 miles later again... Pcv doesn't look to be bad nor does the egr.. but idk does anyone have a solution? i know past owner said he cleaned the throttle body idk how i didn't ask.. this ones tricky its got me stumped.. might just replace the TB what do you guys think?

Also C121C is coming up all iv read is PCM or ABS module, but i have no lights indicating theres a problem with that. the lighting bolt isn't showing up no limp modes doesn't fell like I'm loosing power.. If anyone can help i would appreciate it a lot.
:confused:
Thanks
