I have not had any problems with my truck until we changed the spark plugs recently. Was running strong when we changed them out then after about 2-3 weeks it started giving me problems. Will be driving down the road then it won't accelerate anymore and when you try to give it gas when it's acting up it kills it instantly. Will start up but will turn right around and die, occasionally it will start up just fine and run without any problems but doesn't last long if you do much driving around. Any ideas would be greatly appreciated!

 

Check fuel delivery first, - pump pressure, filter.

NOTE: If you used Autolite plugs in that 97 (103's/104's) then that could be the problem as well.
