Hey guys i know this has been discussed but i cant find this problem else where and dont know where to go from here. I just changed the spark plugs on my 96 gt. When i drove the car the first time after changing them the car was VERY rough. so rough that i thought the car might fall apart in fifth gear. When i got back to the house i triple checked all the wires with three different diagrams. Does anybody know what else this could be. Could i have put the actual plugs in wrong?

You probably didn’t set the gap on all the plugs correctly. Pull all the plugs and set the gap according to the owners manual. Good luck...

what plugs did you put in? if you put one of those gimmick plugs in that is probably your problem

yup, make sure you gap them. I think its .054

Did you get the plug wires back on the correct plugs?

Did you replace the wires? The boots may not be making good contact on the plugs.
