[apecakes]

searched up and down but didnt find any similar issues...

heres the numbers:

high speed standards:HC(ppm): 220CO(%): 1.20DILUTION: >6.0

high speed results(@2628RPM):HC(ppm): 98 PASSCO(%): 0.49 PASSDILUTION: 14.09 PASS

low speed standards:HC(ppm): 220CO(%): 1.20DILUTION: >6.0

low speed results(@713RPM):HC(ppm): 484 FAILCO(%): 4.27 FAILDILUTION: 16.37 PASS

have no idea where to start. high passed, low failed... wtf? im about ready to scrap this and get an old car so i dont have to deal with this new emissions crap.

Check the fuel pressure regulator; there may be too much pressure at idle causing a possible rich mixture. Also do an ECU code readout.

thanks, ill check it out now (just getting around to it... busy busy)

anyone else have any ideas? ive asked around and spark plugs have been mentioned. but mine are regular old NGKs with the FSM gap, so i doubt thats it.
