I am failing smog miserably - -
I failed smog the first time with high CO and HC on both speeds.
Took her home after reading on here about Vac lines, smog equip, & seeing the post that seems to deal with all things emissions(egr/rough idle/rich/lean/IAVC) I realized one of the vacuum lines running to the tree under the upper intake was rotted away. Everything ran correctly, and voltages check out, and i have searched this forum and seen only info on smog delete or "what if..." scenarios. So this engine is for the better part stock and just is failing like a mother(see first pic for numbers)
Fixed that, ran the OBD tester came back flying colors (all green dots and an 11 code on both KOEO/KOER) No codes and I do have a functional CEL light because it's an Original CA edition.
The salt and peppers have been cleaned and all the pins were/are straight.
I took it back and failed even worse! Almost 800% increase of NO and about another 100points on the HC(PPM) over it's original. So now i'm failing all categories and the references in the almighty smog post says bad cats, bad smog eqp. etc)
Driving me nuts!!!
Emotionally and Financially exhausted(pun intended) with this car.
The engine being rebuilt about 1 year ago has about 8k new miles on her.....when i first took it in it passed - -barely.
I keep everything clean and i have gapped my plugs to spec, timing is at 10 with the harness equipped(the thing that advances/retards timing under load) Also the EGR has been replaced, fuel pressure is right on(stock injectors) I am stumped and i don't want to take to a specialist because i have a feeling they'll charge me out the ass just to tell me what the gen. consensus is on this page...bad cats, bad smog parts.
Anybody offer some help why everything F****n skyrocketed into failure.
