... take it back to the mechanic from hell. Does anyone know what is wrong with this car--do not, i repeat, DO NOT, TELL ME I NEED A NEW CATALYTIC CONVERTER, cause I will cry. The cats do not last forever; after 100K miles (if you're lucky), they tend to get pretty clogged/crumbly . . . The test readings were fine at the RPM of 2500 but the car registered more than twice the maximum allowable "HC PPM" and more that 3 times the maximum allowed CO2 at idle speed. I hope this makes sense, probable not but give me you best shot of advice Sounds like (ignoring bad compre$$ion re$ult$...which i$ bad new$ any way you want to look at it) O2 sensor old/clogged/not responding fast enough, although could also be bad static mixture adjust. -RDH
