Install new plugs as a first step for backfiring.
Is the speedometer setting any codes?? This is the first step in diagnosing it. If it is erratic you may have a speed sensor problem or a wiring or connection corrosion or loose or broken conductor or connector problem. Please post a comment with the solution when you find it.

Electrical issue

Sounds like a poor connection at the battery or alternator. You need to make sure there is no corrosion or faults in these connections. If there is no fault there then you likely have a ground problem. Find your engine/Chassis ground, make sure it's tight and again free from corrosion and fault. Leaking battery acid can eat wires on the possitive and ground causing issues. Also if the car has been in an accident it could also have damaged or lossened the ground.

Problems with my 1999 Pontiac Grand am v6.

Check the wiring that plugs into your speed sensor that is attached to your transmission. It is likely that it is loose, broken or both. If it is loose, the speedometer is getting eratic readings from the sensor. Therefore, it will jump around. The same thing happened with my 2002 Grand Caravan. But in my case, one of the wires was chewed through by rodents.

Im having a big problem finding ut what is causing my speedometer to just go haywire.. some times its dead and other times its jumping like crazy.. do you think its the pin that fits into the transaxle...

If the speedometer has a cable from the transaxle, the cable may be broken or ready to break.

No cable? The vehicle speed sensor may be bad. The speed sensor may be on the transaxle but it may also be on the back side of the speedometer cluster. My car has a cable and the speed sensor is on the cable right where it plugs into the back of the speedometer.

Both speedometer & tachometer not working, both reading wrong.

"The Fix" works...I would have not believed it untill I did it.... Start the car in reverse and about 5 times later it reset the speedometer back to!
