Message: [QUOTE="cbuttre835, post: 1484978, member: 1190"] My 2002 7.3 automatic has developed a deal where it gets weak after about 2-4 miles every morning. It acts like you let off the throttle, then starts missing and loping, smokes very faint blue, and then clears up. I live a mile from the interstate and at 70 mph it'll clear up after 15-30 seconds. Well, today I take the back roads, get a half mile from home, and it quit. Didn't have enough speed to ride it out. Towed it home, got it started on ether (disconnected IAH and GPR) and after a few seconds it would run on its own. If Iet it idle itll run for 15 min fine. If I run the throttle up, it'll do the same thing, and lope real bad for a while, before settling down. Fuel looks OK, didn't check the oil level (its on a slight grade) but its not old. Amsoil 15-40. Cracking drain valve with key on indicates good fuel pump flow, but I haven't checked pressure. Where do I? (no schrader valve like on an OBS) Tach never stuttered or dropped out, and I got no CEL. Haven't pulled codes yet. What other easy stuff is there to check? [/QUOTE]
