1 bank runs rich Hi everyone
i have a problem, im running 2004 crate GTO engine in 1988 Camaro with pretuned GTO computer (no Vats and calibrated tires, otherwise its stock) and i have a weird problem - bank 1 runs rich as hell, 0.8 on both 02s; and bank 2 runs around 0.46-0.48...a/f is 14.6 im confused - what can cause it?
im gonna try to swict 02s around tonight and see if its gonna do anything
does anyone had a similar problem before?

Look at your fuel trims and discover if the car is trying to compensate for the lean. Your trims should look like a runaway train if your 02's are reversed. If not, check your fuel pressure. Then maybe you have a problem with your fuel rail restricting fuel to the passenger side.
