Just a little question for all the experienced guys who know alot about troubleshooting this trucks. Well to begin it started running really rough but after taking it to a shop they informed me that it was the Idle Air Control Valve that would make it run like it did. Just curious does it run like crap when that sensor goes out. They had to order the valve because they could not find it. People please chime in on previous experiences that you have had with your Ls. Just trying to get my L running like it did before. Thanks in advance for all the help. :rockon:
