ok, so heres the story. 1994 chevy truck, 350 thats throwin a code 32. it has headers, and true dual exhaust. now the o2 sensor is only on 1 of the pipes, instead of reading all the exhaust it reads half(one side) . would this confuse my truck and cause it to throw this code? i have replaced the egr valve and the egr solenoid. i have checked for vacuum leaks, but cannot find anything. any easy idead/cheap ideas ? also, it like "surges" at about 50-60 mph, and kinda seems like it misses, but not really, its weird.
thanks for the help
