Jeep grand cherokee 2.7 diesel 2003 injector the one under the dash.( difficult to get at number 5 cyl.

Bad news buddy . Busy with one myself . The engine needs to come out , or at least a foot or so forward . You have to strip the whole nose of the vehicle . Remove the injector , cut the seat , install new washer in the head, and assemble .

Hi there, do you get water from the air conditioning unit entering the passenger foot well, if so then perhaps water is dripping onto the electrics below and causing these problems (blocked evaporator unit) alternatively, get jeep to reset your system (2 minute job) and this should work, keep an eye on it as the first new code that appears should be the problem area, hope this helps

Missing when warmed up

ok,so theres no warr. on the repair you had done,your p0205 code is a problem with injector on cyl.5,could be inj.itself or elec.circuit,and thats your main problem,you can take a chance change inj.or bring it to a good mech.,who will hook up a special diag.scan tool to cars comp.and take readings while engines running to pin point problem exactly!thats up to you.
