ok heres the issue. get in the car fire it up, let it warm up. take off. drive easy every thing is good. if you have to lay into it, it will buck jerk and raise all kinds of cane. let out of it and slowly get in the gas and it cool. here is what i hav found so far. someone put a big monster tach in the car and tapped into the wires in the dizzy. when i first got the car it had this same deal going on I found a bad terminal on what looks like an ignition control module fixed the terminal problem was gone. then 2 days ago started doing it again. reall just want to confirm that the dizzy is bad. if anyone has any advice i am open to any and all help
