VS running rough, misfiring under load

[Robbie Waters]

Possibly O2 sensors. Mine is running like an absolute piece of junk. I’ve changed leads coils and plugs, I also cleaned out the entire inlet manifold top to bottom/inside and out. aswell as changing a bunch of sensors. Still running like crap tho. A really good mechanic friend of mine told me to replace o2 sensors. I’ll let you guys know how I go...

NEED HELP!!
My 97 vs 6cyl idles like a bag of ****, like its short of fuel, kind of hunting revs, and its up and down all the time hot or cold. runs beautiful when u put ur foot down and thrash it, but really struggles just to cruise along and misses if ur not giving it a gut-full.
Ive done plugs, leads, coil pack, intake manifold gasket, injectors and im ####ing stumped.
