Just bought a 92 RS, 305 TBI/stick, and tach stays pegged out (past 7k) whether car is running or not, but when i crank it, it jumps BACKWARDS to 4k, before returning to the pegged-out position and staying there.

ANyone?

 

Maybe

Yeah, i just saw that...im gonna try it as soon as my led dash lights come in, so i dont have to go into the dash twice.....

 

That was it! I put 2 100k resistors together and soldered them between numbers 4 and 10 just likee it said, and it worked!
New problem: put in the led lights and some of them dont seem to be on, but its the same ones that werent on before i put the new bulbs in.
