i have a 94 chevy 1500 6.5 152k. the service engine light will blink on for a minute r two then go off continuiously.. its stalled on me a few times but picks right back up. i was told that the injectors maynot be lubercated and then told to put a quart of ATF in a full tank to give it some lubercation. well after i did that and got her on the interstate the service engine soon light only came on one time sfter i slowed down in a small 35mph town after say 170 miles on my trip home. Im wanting some help on what may b the real problem r if anyone else has had similer problems..
