What fault codes are present? What does the scope tell you? It sounds like a computer problem like a sensor giving off bad info to the control module. Just a guess.

AFTER A WEEK OR SO, JUST ABOUT ALL OF THE INJECTORS WILL SHOW UP, BUT 171 SHOWS UP AND 551 ALSO COMES UP. COULD MY POWER STEERING SENSOR BE CAUSING THIS PROBLEM?

djennis20,
Check out the post "p0171 code will not leave"
I mention in there about a problem that has occurred with the power steering pressure switch/o2 sensor. You might want to check it out.

THIS PROBLEM SEEMS TO HAVE BEEN SOLVED BY REPLACING THE POWER STEERING SWITCH, CLEANING UP THE WIRES, AND REPLACING THE O2 SENSOR. THANK YOU FOR ALL THE REPLIES.
