replace the rubber o rings u may have to replace the injector if its leaking fuel through it
could be a vacuum leak
Depends on where the leak is.
matters where the leak is at
someone told me $500+
one of my injector are leaking and can I fix that by replacing small o-ring? Thank you
I suppose if you had a leaky injector it could.
I had this same problem with my 96 Voyager. It ended up being the timing cover which is expensive if you have a shop do it but to do it your self saves you about $400!
Fuel leak, or Fuel Injector stuck partially open.
To determine if you have a leaking injector seal in a 1992 Oldsmobile Cutlass, look for signs of fuel odor near the fuel injectors or a visible fuel leak around the injector area. You may also notice rough idling, poor fuel economy, or a misfire when the engine is running. A diagnostic check can reveal trouble codes related to fuel delivery issues, which may indicate a problem with the injector seals. Additionally, performing a pressure test on the fuel system can help confirm if there’s a leak.
bad o-rings or not seated and tightened down properly
It would be very unlikely. Fuel injectors give very little problems.
Either the "O" rings are bad where the injectors go into the cylinder head or the electrical connector on the injector is leaking.
