Check if your speedo counter is mechanical the is the cable either broken on the gear box side or behind the dash. If is an electronic one then check the electronic speed sensor on the gear box.
Good Luck Emma !

The following asumes only one wheel is hot and the e-brake is not engaged or possibly hung up from having been left on while the car was not driven for a while. Up north, BMW (Audi ?) brake disks tend to start rusting after about a week of inactivity. For a hung up e-brake, it is sometimes necessary to go back and forth to break the corrosion.

A hot wheel usually indicates that the brake pad is dragging (i.e. the brake caliper piston is not returning into the brake caliper bore).
A couple of checks: measure the brake disk temperature with a temperature gun on both brake disks of the same axle. If one is much higher, the caliper piston is probably sticking. Can also check for relatively large temperature difference with your hand-just do not touch the metal or you will get burned. Look at the brake disk for evidence of the outline of the brake pad that may have transferred to it indicating a very hot brake disk. Chock the car well, put into neutral with e-brake off, jack up "hot wheel" side and try to spin the tire. If a lot of drag, sticking caliper piston. Caliper replacement or disassembly for a thorough cleaning will probably be required. If this is necessary, you should do both brake disks and pads and consider doing both calipers on that axle depending on age and corrosion condition.

In most case's the vehicle will stall but won't continue to run or just a flat no start the crank sensor tell the computer the firing order and when to firer where the cam or distributor sensor tell the computer where number one cylinder is note that the crank sensor my hold both sensor in one. If you had a distributor less car it can affect both fuel and ignition system where as if you have a distributor it would more likely affect the fuel system only. I have seen bad sensor that just made for a poor run and low power do to a bad out put signal to the computer. Check it with a scope for a clean signal back to the computer.

2 things here, using oil & white smoke,
1. i would use a product made by seaform called motor tune-up, you can get at napa,autozone or kragen, pour contents in oil and drive normal, this product is real good been using over ten years it will clean all the carbon around the rings & pistons and also clean lifters,sludge in motor, run in for about 3 weeks then change oil stuff costs about $ 9.00
2. White smoke out exhaust is either automatic transmission fluid from transmission or slight head gasket problem
