Ok. Im getting pissed.

Went today to test and I get this.

HC: My car: 1.90 Limit: .80
CO: My car: 21.49 Limit: 12.00
NOX: My car 4.11 Limit: 2.00

Failed every single test... AGAIN...

I redid the wiring on my IAT according to shbox's site. Reset the PCM by disconnecting the battery and started it up. NO DTC's at all. Leave to emissions, waiting in line... POP SES light comes and I fail once again...

I need help..

Thanks in advance...

Wow, that's a big change in CO. Could be burning rich or a cat is going out. And with no EGR you are probably going to fail NOx every time.

 

What im thinking about doing is getting a PaceSetter ORY, getting a Magnaflow cat and bolting it up that way....

How do you check a ground? (I knw stupid question...)

But I need to find out why my PCM is throwing a MAF code...
