*911*Engine Missing Out and Sputtering

so when i take off my motor bogs down and spits and sputters, have brand new plugs, plug wires, distributor. will run great after about 4000rpms but between idle and then it sucks! anyone have similar problems?

injectors maybe, clean them or replace, sounds like a fuel problem

Id check Fuel pressure, and such, the other thing is it could be a timing problem, if your timing belt or chain ? Ive seen belts slip a tooth before.

I had same issues on my 94 years ago. Turned out to be a MAF sensor. Sucked buying a new one.

Haved you replaced your fuel filters? Try that if you havent, then check the fuel pressure to make sure that all of your injectors are putting out enough fuel.

oh its getting enough fuel, running rich actually, and timing is perfect.....
