Many of you have been following my progress, and I appreciate all the help. Today I failed my CA smog test with the following numbers
RPM %CO2 %O2 HC Max HC Meas CO Max CO Meas
Idle 8.0 9.3 120 280 1.00 .14
2500 15.0 .3 140 48 1.00 .17
So at 2500 rpm I'm golden. Idle though.... not good. Smog guy wants me to get a new cat. Before I put down a small pile of money, does anyone else have any suggestions? When I put the new motor in, I replaced all my vacuum lines and torqued down all my IM hardware.
No CEL, car runs really well now that I've replaced my knock sensor. Exhaust does kinda smell "eggy".
All help is appreciated.
