I have tried changing fuel filter, air intake, purge valve, but have the following on my OBD II Pocket Scanner Codes 0, 2 Inc. Evap & Catalyst. 5 Ready Fuel, Comp, Misfire, 02 sensor O2 Heater. I have did the drive 3 minutes at 55mph drift to 20mph drive at 55mph 5 minutes. I repeated this 5xs and still get all the above on my scanner. Need to solve this issue For Pa. emission testing (which is so unfair since only selected counties have to have it done.) Any suggestions?
