Car is running horrible 1993 Z28
OK I have a 93 z28 6 speed, the damn thing is running very rich and when Im driving it feels like something is trying to hold the car back in a sense. the shifter shakes more then it should when the cars in gear and when I hit about 3-3500 rpms the car accelerates very slow if hardly any. I was thinkin about an optispark being the prob but i dunno i did plugs and wires a few weeks ago and that helped some. I replaced the opti like a year ago but I dunno whats up if anyone can offer any help, ideas, suggestions all would be very appreciated thanks

Change them and reset your PCM.

No it doesn't. If it stored a code it WILL flash any stored codes even if the SES Light is off, unless the computer has been cleared.
