Default Back firing on idle and and decel

So i have a 98 ram with the 318, im having some issue and cannot figure it out.
On idle and start up and while on decel the truck backfires like crazy, i have an idea and that being the sprak plugs or injectors. Any ideas? Thanks

Inspect the cap/rotor plugs and wires would be a good start.

Nope. Don't use those. Standard copper plugs only. Otherwise, you cause more issues than you are trying to solve. These engines simply do not like the rare-earth plugs.

Possible, but, not likely.

Does it just crank, and not fire?
