Question about 2003 Jeep Wrangler
2003 Jeep TJ/Wrangler. 4.0L I6. At around 4000-4500 RPM, I get a sudden power loss along with a high pitched squeal, that sounds like a tea kettle going off, or a tire deflating.
Belts seem fine, no vacuum leaks (though at that high of an RPM it would be odd). Happens in neutral or in gear.
I get no engine codes. Vacuum pressure seems fine. Oil level is good. No idling issues, no fuel issues. It's not burning anything.
I was thinking maybe a clogged catalytic converter ? Though again the sound seems to be coming from the engine bay. Don't think I have any exhaust leaks either.
A friend had mentioned to me that the jeep does feel sluggish lately.
Sounds very similar to http://www.fixya.com/postquestion.aspx?trysame=1&thid=2338920&prdid=693384&ctgid=0&msgid=5875251&ref=spb .
Sounds like the mass air flow sensor to me.
