Passed CA Emissions

[Ccmano]

I'm shocked! Just passed my CA emissions!!!

I'm running a Haibeck/Henderson/Sorresso chip, ported with a 4:10 rear end.

Just put the stock manifolds and cats back on.

Not sure if it helped but I put in a bottle of "CRC Guaranteed to Pass" additive and a fresh tank of gas and ran her down the highway about 10 miles. There's a lot of good feedback on this stuff on the net. Particularly on the ThirdGen (Camaro/Firebird) forum. Based on what I have read it's especially good on knocking down NOx. But then again I have relatively new O2 sensors, injectors and plugs. Not to mention the 4:10 rearend.

Here's the report.

Hans,

Great news on passing, I think that as long as your engine is in good running order w/good factory cats, you will pass.

I cant understand these low numbers,my car with 6000 miles tested 593 at 1950 RPM at 25 MPH.

Stock chip with stock timing should bring your NOX down enough to pass.

Just failed for the second time.Got the Max Nox level down to 638 but nowhere under the Max 502 it needs to be.Im off to see a smog Referee in a week.Have no idea what thats going to be like.I just might have a $40,000 paper weight in my garage until these D!CKHEADS that run the State start doing the right thing,like thats going to happen.I cant be the only one in the State with this problem.

not to hi jack, but has anyone with the secondary delete prom from mark tried to pass smog in there area ???

Jeff just do what most of the guys that are running around with LPE385-415's and no cats do. Either get it registered in a county that doesn't require emissions testing or just pay somebody under the table to give you the sticker. I've got a guy like that. I have a Mazda 626 that has had a check engine light on 6 years now. I give him $80 and does what he does and o get a sticker and a proof of pass document.

Jeff,

There has to be something wrong with your cars emissions system based on the results I'm seeing posted here including mine. It's very possible that the ultra low miles on your car contributed to the issue. Constant cold starts and little driving to get the cats heated over 20+ years may have contaminated the cats and/or the O2 sensors. If I were in your position I would start with a bottle of the CRC additive to see if that cleans the cats and sensors as it says it does. Next I would change out the O2 sensors, they're not that expensive and relatively easy to replace. They may be leaning your motor out too much if they're off. Then retest to see if there is any impact.

Keep us posted.

I tried the CRC stuff as well as the stock chip and 5 gallons of E85.Ive got a set of oxygen sensors,wouldnt hurt to put those in the car.
