sorry this may be long. my distributor went out on me a week ago. while the car was down i bypassed the fast idle valve and the intake was ported. got everything put back together and the car idles fine and will rev to redline. as soon as you try to put it in gear and go it starts bucking and the tach needle jumps and the car just refuses to go. theres no check engine light. i have stumped 2 of my mechanics so i m coming to you all here. any help is apprecieated.thanks in advance.---joe

 

Possible the ignitor which is located inside the distrubuter. Also check your rotor and make sure its not loose.

 

new remanuf dist put on today rotor looked good.the tach needle jumps around too if that helps

 

Do you have an aftermarket tach? usually a bouncing tach is a sign of a bad distributer. Make sure you check all of your connections to the distributer. Look for any lose or frayed wires too.

 

Hmm... My stab in the dark would have to be Ignition Timing or the Ignition System is not getting enough current..

If the system isn't getting enough current, it can cause the engine to not let the car run above a certain speed and other weird problems..
