Gasoline port fuel injectors - Keep clean/Clean up with additives
Gasoline Port Fuel Injector (PFI) plugging is a relatively new and unexpected problem in the field. In the Fall of 1984, there was a large increase in car owner complaints about poor driveability at low mileages. This occured in a narrow geographical area around Denver, Colorado. Most automotive engines with PFI systems are subject to the problem. The rate of injector plugging is primarily affected by the hydrocarbon composition of the base gasoline and the presence or absence of detergent/dispersant additives. Deposits that form on the injector pintle tips restrict gasoline flow to the cylinders. These deposits continue to build to a degree where engines misfire, run rough, lose power and are difficult to start.
