smog vs check engine light
after passing smog several times, my corvette check engine light would not go out. Car ran well but would not pass smog. Codes 24/34 & 36 and computer bad. Replaced, and After many hundred of $ Co 2 sensor replaced but chk engine light still on. I replaced air flow sensor and finally light is off when start engine. BUT now will not idle, therefore will not pass smog. Any help?

What MAF sensor was put on as a replacement? There are some that just don't work. It would be well worth it to buy a scan tool that reads live data-you can find them on e-bay. Like an Auto xray ezlink. With that you can look at the gm/sec.the MAF sensor is reading out and if it's off it will be apparent what's going on.
