Electrical problem
2000 Daewoo Leganza 4 cyl Front Wheel Drive Automatic 109000 miles

Hello,

I have a cyliinder 4 misfire on my car. I put new spark plugs and plug wires and still get the misfire. The car cranks but but runs really slow and the front end shakes and the exhaust gets hot, so hot it melted the plasitic splash guard under that area.... you also have to mash the gas to get it going just a little. Would you have any ideas of what else it may be? I will next try replacing the fuel filter and see what that does, but any help would be appreciated. Thanks.
