I don't believe it!?! My '95 Talon ESI (132k and no mods) failed its drive clean test. Here are the results:

ASM2525 Test
(test / limit / reading / result)
HC ppm: 74 130 FAIL !
CO %: 0.41 0.28 PASS
NO ppm: 547 83 PASS
RPM: 1838 VALID
DILUTION: 15.3 VALID

CURB IDLE TEST:
(test / limit / reading / result)
HC ppm: 200 194 PASS
CO %: 1.00 0.21 PASS
NO ppm: n/a n/a n/a
RPM: 871 VALID
DILUTION: 14.8 VALID

Any ideas on what might be wrong before i
shell out for the Drive Clean diagnositic test?

It blows me away, because i'm religious about
the oil changes and maintenance schedule. Two years ago my car passed with these results:

ASM2525 Test
(test / limit / reading / result)
HC ppm: 74 24 PASS
CO %: 0.41 0.03 PASS
NO ppm: 547 65 PASS
RPM: 2498 VALID
DILUTION: VALID

Any ideas? I've only got 2 weeks to go before
plate renewals...

thanks in advance,
Frank
