1997 Plymouth Voyager engin boggs out

Ok here it goes, at a cold start my van runs ok not great but ok, the temp gauge rises to half way in a quarter mile and it starts spittin and sputtering I have to fether the gas pettle to keep it from killing the temp never over heats but engine losses almost all power. The check engine light comes on and reads low fule intake or somthing like that I get backfire in the intake. Things I done to the engine I replaced spark plugs and wires. Intake gasket 3 times, some vacume lines, fule filter, egr vaulve, temp gauge, I put a hole in the cat. Any one who can tell me how to fixes it i'll give 100 dollars thank you.
