MUltiple Codes/ P0455. PO441.P1300.P0306.PO300.PO301
Hello All,
Rover running rough for couple of months with no codes. Replaced plugs with Champion double platinum. A little better. Then the 3 amigos and M 7S lights. Replaced rotors and pads. all good. The the PO4455 gas cap crap. Strong gas smell in hot weather. Replaced purge valve and erased code. 300 miles later all ofthe above codes. Running 93 octane and no coolant loss. Will try brake cleaner on all vacuum hoses and mist wires at night for spark and add sea foam but ..Am I wishing?
Replaced O2 sensors 2 years ago when thieves stole my catalytic converters. Is it the coils and wires? can it be anything else. They are original.
There are no coil relocation kits around and the fix in New York is $900 smackeroos.
Please advise.
Thank you,
Jeff

Thank you guys. I planned on replacing wires and since I'm removing plenum might as well do coils. However the evap codes 0441 suggest a vacuum leak or bad charcoal canister, purge valve issues could be causing the misfires. Is this a possibility? I plan to pick up a vacuum gauge and or blow smoke into a hose.
