Hey guys today I took my car in to be smogged (im in Cali.):mad: and my car failed. the PO said he had a new cat installed about two years ago and 19,xxx miles ago. It looks fairly new. I have a Mark d 91 oct. chip. Are these smog legal? heres my numbers

Hc max 124 / meas 227 15 mph
98 / meas 202 25 mph

No 815 / 2726 15mph
754 / 2017 25mph

on the previous test when I bought the car the numbers were well within range. I warmed up the cat and the guy even tested it twice while letting it warm up some more.
any thoughts welcomed.
thanks in advance

Check for vacuum leaks, looks like you might have a biggun.

Thanks, i replaced all the vacuum lines under the intake and icv about a year ago but i noticed that some are already looking a little cracked mainly the one on the ICV to the head. The cars RPMs dont seem to bounce around very much if at all. wouldnt this bad of a leak be noticeable?

Yeah I would think so, could also be a lazy O2 sensor though.

Swap the stock chip back in for the smog check. This engine routinely fails with aftermarket chips.
