I have a 93 mustang 2.3. I was driving home and my check engine light went on and the Tach started bouncing all over the place. There was no audible change in the RPMs though. After about 2 minutes the check engine light went off but the Tach kept bouncing.</P>


Ihave twin spark so maybe something went out and I wouldn't know it maybe?</P>


Any help is appreciated</P>

 

hmm, interesting, sounds kinda like the computer or ignition module is having fun with you or something.</P>


my best advice would be to get the trouble codes pulled and figure out what they tell you, since it triggereed the check engine light, there will defenetely be a code</P>

 

Thanks for the tip. I'll try that.

 

definitely computer that one and get the codes...never heard of that kind of fun before....jenna
