The Saab only repair shop does all these test/replacement:
Compression test - ok
Replaced new O2 sensor
Try replace Air Mess sensor - (put orig back on)
Try new cat (aftermarket); make no diff - put orig back on
Try replaced the computer from a passing car for smog check - put orig back on
Replaced new by-pass valve
Vacuum test for vacuum tank - ok
New spark plugs
Check & adjust timing
Check, adjust & clean throttle
All the above cannot drop the high NOX in my car. Gold Shield station says that they can't do anything for me.
I add fuel injector cleaner in my fuel tank.
Since C0 is 0.00 which means the fuel mixture is too lean and cause high NOX. What else I should check in my car? Vacuum leak? Fuel pressure? Wiring Resistance? What the air/fuel mixture suppose to be if I use the air/fuel gauge to check the mixture?
Any expert can give me some more suggestion/brain storming?
Thanks a lot.
