Hydrocarbon problem
#23
Its been a while since i posted about this but i finally resolved my issue about a week ago i havent found time to post again but i passed emmitions. What i did was after the last post i made i went back and failed again so i bought a cat and o2 sensor. The cat is from Davico and hooked up easily and the o2 sensor was bosch. I had no issue with putting them on its fairly easy. But anyways i installed those and put some premium gas in and drove about 75miles on the new parts before going to the testing center. Mostly was highway miles and i passed with HC at 54 max being 220. Its clear those were my problem areas. The cat had white dust falling out of it when i had it off i hit it with a hammer and it would fall out. The o2 sensor was completly black. Those 2 parts ran me 111$ from rock auto shipped. took about a week to get here. I hope this thread helps out for anyone with similar problems and thank you for everyone who posted here.

Yup, you're completely correct, Premium has no more cleaning ability than does Regular.
