okay guys i took video of what its doing can somone help me out here i have changed the FPR , 02 sensor, cleaned the egr ports new plugs/wires/cap and rotor and drove it on the highway for a while so it was nice and hot. the only thing i didnt change is the cat. here it is at idle whatch the top left box it jumps way up.

that video didnt help much but my dad is going through the exact same thing with his lexus.

it would get up to 900 HC at idle but right when it is off idle, it drops significantly and on the dyno at 15mph and 25mph, it actually passes, lol.

im leaning towards a vacuum leak or off cam timing but cam timing on a sohc would destroy the smog. my dad's lexus has 4 cams

put a vacuum gauage on your manifold. should stay steady between 17-21 in-hg

yeah see when he revs and holds it at 2500 rpm it will pass just when its sitting at idle it does this. ill try the vacuume leak thing again but i am almost positive its not that this is such a bitch i swear

a low compression cylinder might cause high hc's

It shouldn't matter. As long as u pass the first and second run. Then your fine.

well today is a sad day for me, my CB is getting a non op until i can fix it or finish building my h22 and swap it in and get it to pass smog. but for now ill be driving my new 04 dodge ram that i bought
