Changed all fuel injectors and runs rich..too rich
I have a 1994 Chevy Camaro V6. It was running a little sluggish: it would stutter really bad. So I changed all the sparkplugs/wires. Still stutters. Took it to a shop where they said the #5 injector was bad so I brought it home and changed all the injectors. It doesn't stutter anymore but it still runs a little sluggish and it is running so rich! You can smell the gas coming from the exhaust: not to mention I am getting very bad gas milage...very bad.
Any ideas on way it is running so rich? do I need to reset something? you know, that maybe as the old fuel injectors were getting worn and not straying an optimal amount of fuel, so the system compensated somehow and now that needs to be reset?
