1996 chevy tahoe

Question

my tahoe is tripping 4 codes P0304, P0131, P0151, and P0441

Answer 1

P0304  Misfire number 4 cylinder

P0131 H02S Circuit low voltage Bank 1 Sensor 1

P0151 H02S Circuit low voltage Bank 2 Sensor 1

P0441 Evaporative system no flow during purge

With these code check the canister purge solenoid , if the purge is not seated in properly it can cause a misfire code condition, and a no flow during purge so the purge solenoid has to be ruled out,
