Just replaced the injectors....egr cleaned. Everything back together nicely. It was running like crap prior. Seems to have more power...but serious hesitation when stepping on the gas (especially under load)...some popping. Any ideas? Suggestions?
they seem to be seated....but how can I really tell? I mean, the rails are all bolted down, etc.
cant tell NOW but when they go in, make sure they snap top and bottom positively, also, make sure the old orings come off, they will fit in with two orings (by mistake) on top of bottom,and they wonr really leak enough to tell.
remove negative battery cable , and turn headlight switch on TO COMPLETELY DRAIN ANY RESIDUAL VOLTAGE FROM THE ELECTRICAL SYSTEM ,ecm and radio capacitors can carry enough residual voltage to NOT CLEAR ALL THE CODES , I just did my injectors today and it WORKED FOR ME
So I finally changed the S.O.B. fuel filter....and cleared the codes. And no "check engine" came on. Seems to run a little better...except for that hesitation/bogging when you put your foot into it... starting to kinda **** me off!
Did you check the fuel pressure? I did my injectors and then a couple weeks later the fuel pump crapped out. It can be tricky, my pump would work ok when it was cold but once it warmed up a little forget about it.
It's the other way...when it is cold it runs like crap (bogging when you stomp on it...rough idle). What is weird: so it's running/idle rough...I disconnect the MASS AIR plug sensor plug...it seemed to run better. ???? Any ideas?
