changed my plugs and wires yesterday...The truck is running rough (Ideling rough and poor accelaration and sluggish) just as it did before a changed the plugs and wires....I have no spark at the #5....bad coil or something else...

 

post the year and mileage in your signature. have u cleaned the throttle body and/ or done a seafoam induction cleaning? what type plugs and wires did you use? what grade fuel have you been running?

 

2001 disco LE with 99370 miles...magecor wire plus 4 bosch plugs....haven't done any throttle or induction cleaning...premium fuel most of the time.(sorry)..

 

first, just go back and make sure all the leads are snapped into place properly on the coil pack. its just too easy to not have em all pushed in all the way.

if that is clear then a induction clean is something worth trying, but i am thinking it might be the coil pack. but make sure all hoses and vacuum lines are tight just in case. do all the cheap and easy things before spending more money.
