Hey wsup guys,

I have the 91 mr2 turbo and it won't pass smog even with the cat back on. The NoX numbers are twice as high as normal. I switched out egrs from another car and still the same result. I can't for the life of me figure out what's wrong and I keep getting fix it tickets for expired registration!

 

NOx is a sign of high combustion temperature. The engine could be running lean. Clogged injectors? Bad O2 sensor?

 

i used seafoam, does that clean injectors?
I should try a new o2 sensor then?
