(This is my 1989 Chrysler Daytona, not my RX7).



I failed the E-test. Passed every aspect except CO% at idle. Even though I passed the 40 kmph test, my CO% was still high.



What's a quick fix? Any tips you guys?

Is there an idle mixture screw? You could probably lean it out.

4 or 6 cyl?

If there is I don't know about it. I should probably hit up a chrylser website and find out. It's running high CO all the time. Just barely broke the camels back at idle. https://www.nopistons.com/forums/pub...IR#>/dunno.gif



My RX7's numbers were WAY lower than this when I had it done.. Same with the Cavalier..

4 Cyl 2.5 L 5 spd

Try going to the parts store and finding that stuff that guarantees you pass? If you're not that far over, it should help. Try changing your plugs, too.

I think I am going to go again on Friday. If I don't pass with new spark plugs, air filter, and that pass stuff, then I dunno.. https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Try resetting the factory computer too. Disconnect the battery and hold your foot on the brake for a few seconds.

Woah really?

Yeah. It may not help, but you'll get a fresh "boot" after that.
