Ok a little knowledge can be a dangerous thing, and I have as little as anyone. Here is my (ok, one of my problems), 02 Trac with 41,000 miles. I've been getting CEL with P0171 and P0174 for about a month. I got on the site and checked all the relevant posts. It is not the elbow. I took the whole thing off and checked hoses on both ends and vacuum checked the hole unit, it is good. Had no drivability problems at first, now I'm getting a stumble and it died twice at idle. I have a scanner so I just reset the light every time it comes on. Yesterday while pulling a trailer, I got a flashing CEL for about 15 seconds, then it went out.
Help Mr. Wizard, I don't want a lean Trac anymore.
