sounds like the problem i had with my 99. the SES light came on. cylinder 7 was misfiring. i changed the plugs and wirings. the SES light went out. truck ran fine for a while. now it stalls when i start it. and sometimes it misfires at cruising speed when the rpms are low. truck feels real slow.
you think it is injector, ignition coil, or fuel pump?
