biged30 Posted August 12, 2005 Report Share Posted August 12, 2005 After checking the CEL with my OBDII reader it came up with engine running rich. From reading other post I assume it is either a bad oxygen sensor or MAF sensor. The car doe run a slow on acceleration but gas mileage is still good (27 mpg). What is the eaiest and cheapest way to eliminate one or both of those possibilities? Also I just changed out all 5 plugs, wires, cap and rotor and the codes for misfures came up on number 3 and 5. Did I just plug something in wrong? I appreciate any and all help. Link to comment Share on other sites More sharing options...
