[QUOTE="BrunDog, post: 244436, member: 173"] Just because there are no error codes does not mean the altitude sensor is not working. The sensor may simply be reading/reporting the wrong altitude. For example, you could be at 5k ft and it is telling the ECU you are at seal level. The ECU is not going to think anything is wrong. Have them run diagnostics tests on it and/or replace it. In addition, IIRC, there is a sensor in the airbox that measures absolute pressure there, too. I am too lazy to grab the manual right now, so grab the salt shaker on this one. Before you do this, of course, make sure the problems really only happen at altitude. 2500 or 5k ain't really a big deal, but corroborate the story nonetheless. Generally, problems like this get worse, not better, ad the culprit should become painfully obvious soon. -BD [/QUOTE]
