In response to General Motors request for high-detergent fuels, almost all gasoline marketers now provide fuel which should prevent injector plugging.
In addition to improved fuels, General Motors has released fuel injectors with increased resistance to plugging. The following steps are recommended to
service port fuel injection conditions:
To Correct Injector Plugging:
(All models and years)
1.
Clean injectors, using tool J-35800.
2.
Recommend the use of high-detergent fuel.
Any additional occurrences (1985-1986)
Injectors more resistant to plugging have been released in 1987 fuel rails with date codes after 12-5-86. These injectors cannot be used in 1985-86
manifolds. However, improved service injectors are available for 1985-1986 vehicles that continue to have injector problems. These 1985-86 service
injectors are of a different manufacturer and must only be used in complete sets of eight. The attached chart provides correct part numbers for service
applications.
