i have ran all codes, fixed what needed to be fixed code wise. but it is still starting in limp mode. i hate throwing money at this thing and it not fixing it. please help

 

You didnt give us much to work with. What year is the vehicle, and what were the codes? What were the symptoms? When you threw parts at it, did you simply replace whatever part the code specified, or test everything first? Many dont bother testing. For example, they see TPS mentioned, so they replace the TPS, but dont test the wiring. Sometimes its the wiring and not the part specified.

 

A 95 Jeep XJ does not have a limp mode.

If it is running at low rpm and wanting to die, you have some other problem like low voltage, weak fuel pump, etc.

 

it takes a second for it to start, like it spits and spuders then ones it starts it idles @ 600-1k rpm but its in limp mode. when i try to drive it its struggles and i try to rev it it will rev but it back fires really bad.
