Yet again. Another problem... so my number 4 fuse keeps blowing and my truck sounds like it is misfiring. I have a 92 f150 5.8 4x4. Have checked all other fuses. Have looked at grounds under the hood. Have looked under power dist box. I will replace the fuse and my instrument panel will light up but as soon as I go in gear and give a little gas the fuse is gone again. Truck will still be running poorly. Anyone know a fix?

 

what trans do you have? check engine light on? have you checked for codes? if you replace fuse, and dont put in gear or give gas, is it still running poorly before fuse blows?

 

E4od. And I cant go by my check engine light anymore because my chip. Havent checked for any codes and yes i replaced it last night and when i cranked it was running poorly before it blew the fuse.
