my car has a problem i gone though 2 coils now my car was turning off with the first one my rpm guage was going nuts missfiring first i changed the ignitor had no change wat so ever then the car started turning off and i knew it had to be the coil so i changed it worked good no more missfiring ran smooth but only problem my rpm guage was still acting up and now today now i feel the missfiring again and this coil is about to take a dump also i just want to know what could be causing this? i changed cap and rotor

 

Check your timing, and make sure your wires are going to the correct cylinders.

 

checked timming i have to check the wires no check engine light also

 

Maybe a loose ground somewhere?

 

i would say timing, a short somewhere, maybe a check yr plugs to see if any are fouled

 

i will check my grounds but i changed the plugs after it already had started

 

if I were you check timing, then replace spark plug wires as well as spark plugs.. see if that helps.. also cap and rotor but you replaced that already.
