Question about 1998 Ford Escort
On my sons 98 escort had p codes read p0301&p0304 misfire changed plugs,wires,coil still have same problem just noticed gas cap missing could this be the problem?
Missing the fuel cap may have caused your code, though I would have also expected you to have gotten a code more directly related to a pressure problem in the EVAP, which needs the fuel cap tightly in place and air tight. Those EVAP codes would be from P0440 to P0455

What motor do you have in that car? 2.0L dohc? If your spark plugs and wires are located through the center of the valve cover. The gasket might be bad and leaking oil into the plug holes. This will cause the spark to short out through the cylinder head instead of going through the plug. If this is the case, check the condition of the gasket. If it's hard and brittle it's just old and leaking, but if it's still soft. Then you might still have a blow by problem forcing the oil out with pressure.

Well #301 & 304 miss fire usually it is only one miss fire! is it acting funny? no fuel cap may cause it not to run no back pressure but I would get that coil tested these cars are known for that.
