Odd one, had a slight miss at idle but as you raised the rpm it would buck and the tach would be jumping....a violent Miss for sure. Chased all differnt things down from the mass air, to vaccum leaks, injectors,fuel pressure, coil,plug wires, plugs,compression test. Replaced the Cap and rotor, tested the TFI (ignition module).
Even went as far as to put the rail on a standalone fuel machine, but to no avail!
Finally pulled the dizzy, turning it by hand was tough at best. Was grinding and had alot of play in the Rotor.
Upon closer inspection.....
The trigger wheel had been HITTING the PIP ! It wore a grove on the inside/underside of the window wheel!
Yet the car still started and idled decently! Crazy stuff...but i figured i would post for the archives atleast :SNSign:
Ps: its a 1994 GT
