I had my car smoged the other day again. I had a vacuum problem last time (EGR into TB) Fixed that and now my LTFT are way down. Used to be maxed at 25%. Get it smoged again and it still wont pass smog.

I have high CO% still according to the smog paper. LOOK

15mph CO% MAX=.48
MINE=.91

25mph CO% MAX=.46
MINE=.98

Im thinking my fuel injectors need to be clean and or my spark plug's need to changed out. No mods just a motor swap into my 89 camaro. Have all the emissions, all that crap. Can you give me a hand please. Thanks

not yet, i went to go buy it today. I just put gas in my car yesterday so now i got to waste it. Im also thinking to that it could be my cats... i hope this seafoam works. Have you tried it?

You're running rich. Spark plugs are probably good or HC's would be way up. Also, did the paper show CO2 content. That will tell what condition the cats are in. Should be around 15%

no the paper does not have this info at all. HC, CO, NO thats it. According to the smog ref. the cats are ok cause the rear O2 are stable and read a flat line. im going to try that seafoam and see what happens. Im not that far away from passing. I hate emissions.
