2001 dodge neon, when you take off, the engine will backfire back through the airbox, fuel pressure is 55 lbs, converter is good, i olhm the coil it is good, brand new wires, plugs arent that old, just wondering what would cause this, no codes either, any help would be appriated, forgot to tell you when you let off the gas when it starts to backfire, now it dosent do it all the time, only if you crowd the gas, but it has no power until you gte moving or atleast up to 60mph...

 

If I didn't know any better I would say your timing was off by a notch or two...

 

i agree but before you have a mechanic do all of that.... did you by any chance use Platinum Sparkplugs? if you did i'd say that could also be the problem... go with Iridiums or Copper plugs and that should fix it....
