Has the shop put the computer software on the engine to check the parameters and trouble codes? If there are codes they will show on the printout. If there are no codes and all the parameters show normal then the problem would be in the fuel system.

For this you need to be able to monitor and test the fuel pressures.

Has any of this been done?

Dont know about the computer as he was in the process of hooking it up this afternoon...so i'm uninformed from the start...77 year old men do not do computer stuff too well...the engine went back to doing full throttle at one time...then quit again...off and on ...off and on...

Lets see where the diagnosis goes.

In my experience fuel restrictions and failing fuel pumps cause the type of problem you are describing if there is no trouble codes.

I wasn't on when your request came in. Did you hear back from the shop?
