Re: Engine Running Problems

[jtrealty@xxxx]

The engine will not run smoothly with a lot of fuel injector cleaner 
in the system. You really can't tell if if is running correctly until 
you use up all of the cleaner and refill the tank with 91 or higher 
octane unleaded. In the meantime it sounds like you should replace the 
fuel filter and the fuel acumulater to solve the sputtering at high 
speed and the hard hot start problems. Fuel system cleaner will 
probably not help much if the fuel injectors need to be cleaned. The 
only way I know of is to remove them and stick them in a fuel injector 
tester to clean and test them properly. Also make sure the throttle is 
returning all the way to idle and activates the idle motor micro. Make 
sure the 3 brass screws are LIGHTLY seated closed (they are top center 
rear on the air intake of the motor). A possible cause for the engine 
shutting down when heated up is a bad pick-up coil in the distributer 
(it may also be causing the sputtering).
