Does it start to bounce arounfd 3000-4000rpm..?
Or is this at idle..?

 

You could have a loose/bad electrical connection. Since your in Miami, I can lend you a hand if you need one.

 

it pretty much bounces everywhere.....at idle...low rpm and up high......car is completly stock.......is there any place i should look for a loose ground or connection?....thanks

 

bump ttt

 

It's probably your igition coil. Had the same problem a while back replaced it and the problem went away, just don't buy from Advance Auto because I went through about 6 of theirs before giving up and going elsewhere.

 

really?...did you have any other symptoms?....what exactly did you tach do?...as far as the bouncing?..did the car drive fine?...thanks

Bad igniter maybe?

 

even with the car still running perfect can the igniter or coil be bad??

 

It just bounces or does it bog down too, if it just bounces it's your coil.

 

i just replaced the cap and rotor since they were a lil worn..and swapped in a new ignition coil.....and like magic the needle has stopped bouncing...thank you very much for your assistance...you saved me alot of time.....i really appreciate it
