Ok so my ls failed emissions. Only failed on no ppm, both tests. 1746 out of 1258 and 2008 out of 1378.

Ls block
Type r pistons
Stage 2 cams
Cam gears
Exhaust.

In an 88 crx si.

I zeroed out the cam gears and timing on distributor is advanced, it won't really idle if its in the middle. Is there anyway I can manipulate the cams via cam gear timing to make it emission freindly?
