Take a read through this. I know it'* very long, but it'* informative:

I had a VERY similar situation on a 94 Olds. It ended up being the harmonic balancer of all things. All symptoms were the same as yours, and I did all of the same troubleshooting steps...

Check your HB for cracks in the rubber around the rim. Age may have gotten the best of it.

The speedometer works right? Pop the I/P apart and slide in some junkyard gears.

Please update your title to something more appropriate like Poor idling or something like that.

The car is actually not backfiring, merely running poorly.

well the car was back firing, when runing cold,, fixed,,, after i swiched out plugs and wires it was still runing bad, so i started pushing on the wires to make sure thay where on all the way,, and when i was pushing on the 1st coil it ran good, and when i let go it ran bad,. So i pulled it and swiched it, SAME,, next i cleaned the ICM and put some of that gel,on the ICM and i runs good now,
it seems that the inside on the coil wasnt makeing good contact with the ICM

It still has a stumble at rev up, when i first punch it, but it allwas did that

Sorry if im going off topic, ""has had a small wine at low speeds, but shifts good,""
i know its not good, i just dont know how bad, ive had the car for 4 1/2 years and it always had a wine, never got better or worse

sorry i have many questions just dont want to post tomany topics,

I/P? is that on the side of the tran? and if its a gear, would that wine?? plz say yes

Instrument panel. As for you whine, have you checked the power steering fluid?

No i get that to whiney power steering ,, this whine is from the trany it dos it at low speeds, and gets higher and lower pitch, with the RPM'*

That sounds more like a hub assembly to me.

Its a trany whine

Concur. Also, checked the fuel filter lately?
