Check engine light stays on. changed oxygen sensor, pcv valve, coolant sensor, switched out PROM chip, and cannot get a code to blink. replaced all hoses coming off carb. smog pump and egr valve been...

what you could start with is checking to see what trouble codes are being logged for this vehicle...if the engine light stays on, it means the ecu is registering a the means of a trouble the trouble code doesnt tell you how to fix it, but it does give you the direction to go down...judst wondering if you have tried to obtain the trouble codes

My 1981 Corvette Alternator light stays on and my choke light is also on and will not cut off making the engine race. Do I just need to replace the Alternator? thanks

I would ahve the alternator tested to see if it was bad first, if so I would replace it and see if that improves your choke situation. If the alternator is not putting out enough voltage it can affect other systems in you car including an electric choke system.

Ehgin running rough

You got a check engine light viewing. If so get the shop manual make youself a jumper wire and jump the terminals it tells you to jump and count the flashes for the codes. The ECU/ Brain terminal is under the ash tray. If there are no codes or a check engine light welcome to the wondeful world of being a Corvette owner I 've owned the same car since 1981.
Basically, check the idle,you may want to replace wires, Distributor cap and rotor. Thats worked for me in the past. Once the PCV valve was stuck. Pull it out and shake it if it rattles its fine. You can blow thre it to has to accept air one way but not the other. The shop manual will tell you to do the same.I believe they may go a step further and recommend an oil change and minor cleaning of the carb. I use mine for shows and because I don't run it regularily I get the same problem. I usually let it run for a few hours (ideling of course) lol... and it works itself out . Keep me posted
