Could someone walk me through the procedure/give me tips on how to
replace one sole fuel injector in a 95, 2.2 Chevy Cavalier (160,000
Have a case where I'm smelling a strong gas smell from the front end.
Tracked it down to a fuel injector, around which I could see drying
gas. So, I would think that I would have to replace just this single
injector...or would it be more likely to be the o-rings I keep hearing
about. Regardless, I'm unsure of the procedure. The Chiltons manual
has me taking apart the entire fuel rail, which I'm sure I don't need
to do but am not sure how to proceed.
Any help would be appreciated.
Which end of the head is the fuel residue found? Drivers' side or passenger
side? If it's passenger side, that is where the return pipe for the fuel
system is. I know from experience that if that pipe is not seated
correctly, or the flange that it bolts onto the manifold with develops a
crack OR the o-ring inside the pipe is shot or unseated...fuel will leak out
of there quite steadily once the fuel pump is switched on. It's a common
pain every time I've disassembled either the head or the manifold, or
both...but it's an easy fix.
PS: If it's one of the injectors...well, that's one I haven't done yet...so
you might want to go with a Haynes or Chilton manual for it. I prefer
Haynes, as Chilton is generally written for someone with a well-equipped
shop, where Haynes is written more for an average shadetree mechanic with
more generalised tools. Good Luck!
