This video will show you how to test and replace the bad fuel injectors in a Jeep Grand Cherokee WJ with a 4.0 Liter 6 cylinder engine. The error codes were P0202 and P0302, which are related to the second cylinder misfiring. The injectors are placed right above the intake and exhaust manifold where the heat rises to the injectors and damages them. In my case the second fuel injector was bad and I replaced the set of 6 injectors with remanufactured Bosch 4 hole 24 lb fuel injectors.

Holy Anarchy says:

Great video !!! 2 Question, 1st. after you put the fuel rail back with the inject where was the leak coming from??? that part was not shown in the video. 2nd. did you replace your injectors initially due to the muffler smoking? or what was the jeep doing to make you think it was the injectors failer? Thx…

I have a 04 Cherokee it has a cyl 6 misfire just changed coil pack and plugs are brand new it feels real sluggish when trying to give gas and the check engine light comes on and flashes only when I get on the gas a little hard think it could be the injector ?

JD Armstrong says:

Thank you, great video. Mine requires cycling key several times to start, then runs rough for a few seconds and then clears up. I suspect one injectors is leaking fuel pressure in to cylinder. Can I ohm test to find the bad injector, if it is just leaking but otherwise works ok? This happened after I put Lucas fuel injector cleaner in the tank- everything was fine until then 🙁

Al Ortiz says:
