Hello
1999 ram 1500 5.2 automatic 4wd
I need some help,
During acceleration it stumbles almost like a misfire, shifting at high rpm, and motor has a strange deep Sound during decent acceleration. It has new plugs, wires, all new fluids and filters

 

Did you check if you have any fouled up plugs?
What does it sound like? If you listen near the pipe is it sound bubbly?

 

Checked all plugs, it's a really deep throated sound like aftermarket exhaust. ( still has factory exhaust )

 

No cat rattle? Idle is ok? Wires ran properly?

 

Wires good, idles rough, can't tell if a rattle

 

Checked your plenum?

 

Did you heck for vacuum leaks? Do you have any check engine lights? Do you have anybad fuses?

 

No Leaks no lights fuses good

 

Check your plenum yet?

 

Plenum?
