The injectors i might check last, in that it ran smooth as silk day before yesterday for about 1/2 hour. Today he is checking the FD to make sure fuel is getting to it and then see about the injectors. I am suspecting the FD is the culprit, but clasping my palms. i did see some threads about the coil and the crankshaft position sensor, but the FACT the engine ran smooth for 1/2 hour leads me to believe otherwise.

Has anyone had this problem and solved it? Help is always appreciated.

Thanks!
