today i got 3 check engine light codes...16, 17, 43 one is for my fuel injections system, one is or my fuel management system, and one is for my speed sensro...well today my speedo went out, and the cable is atatched fine, and its not the gauge cluster cuz we swapped one, and its not the fuse...help...also, wha can i do to fix the other problem codes...someone said the dist. could be bad...any truth to that???

 

What obd are you running ? Cause I'm not away of any codes that go that high accept in obd1 and 2. Anyways just making sure you have the right codes.

Code 16 is probably the Main Relay, however it could still mean a bad Injector, Resistor Box tho.
Most failures occur, when the weather starts heating-up for the summer...

For code 17, try taking out the cable and cleaning the end and sticking it back in. And then reset your computer, the end of the vss is basically a magnet so it usually don't go bad.
