OK just put in a another Opti from Autozone... Car ran fine for about a week... then i get on it, it sputters, and then dies.... Car will not fire now... kinda coughs, but thats it.. sprayed starting fluid in and didnt make a dif so im guessin its something with ignition system... disconnected the MSD and put on another coil but still same thing.... didnt check spark to plugs yet but i will do that next... Is it the opti again??? Its warrantied but its a pain takin it off every 7 days cuz its a POS!! any other ideas tho???

Thanks
Jeremy

 

Did you scan it for codes?

General wisdom is to avoid anything other than an OEM AC/Delco (Delphi) Opti.
