Ok well I took the 90 in for smog check and it did smell very rich out the pipe. But literally everything that is normally wearing or even close to it is new under the hood. It drives great and has good power.
Well it failed Miserably! Like 2 to 3 to even 4 times the allowed amount of exh crap. Its even a remanuf. long block. Total on all the replaced parts is like 6 hours of run time.
So I figure screw it and left it with them, they offered a 69$ diag. fee to find the reason. Well they just called and told me that the tech said that theres a Exhaust leak as a ink leak at the TB base and those are going to allow the O2 to think its lean and richen it up.
Well I can barely if at all hear a Exh leak. I welded the manifold up Very well when I replaced the motor. And the TB has been off like 3 times since the eng due to cleaning it and replacing the IAC, and the base gasket looked fine. It idle's a little rough but at like 600-700 rpm's.
So is even poss that those leaks, minimal at best could cause this major failing of outputs in a smog test?
Thanks
