Hey guys i was coming to a stop today, and down shifting. It was reving about 3 grand then all of a sudden it dropped right to zero...and i cant get it to work agian, its stuck at zero? Anyone know what caused this or what i should check for?

 

Anyone know anything about that? i looked throught my car and cant seem to find any disconteced wires, and then all of a sudden it starts sputtering so i decided to take out the spark plugs and there not the best....kinda gunged up...so i clean them off an put them back in and my car don't run anymore...im off to get new plugs i think thats it, maybe it will fix my tach too....if anyone else has had this problem let me know what it was or what you did...thanks

 

anyone at all??? i need my car to run again soon...

 

maybe your car is flooded? Try the deflooding trick.if not basically check for the essentials fuel, spark and timing. Good luck

 

n/a turbo miles mods?

 

if the new plugs don't fix the tach, take a look at the trailing coils for loose or shorted wiring...if the plugs were THAT bad, they may have fried the trailing coil(s)...that's where the tach gets its signal from...

 

I don't see why plugs would have anything to do with tach function, sounds like the whichever coil is responsible for the tach (sorry, I can find it on a diagram but I forgot which) is having trouble.

That or the gauge is faulty, but that would be very rare I would think.

check for spark on the trailing coil. you might be running only on the leading now. if you have spark then it's probably something in the cluster.
