2000 Jeep TJ with 116,000 miles
As we all know if it’s not one thing it’s another. Anyway, I started my Jeep up a few weeks ago, started driving and got about 2-3 miles before I heard a strange whistling sound. Pulled over and noticed that the whistling sound is only when I am off the gas pedal. As I got on the highway I noticed it got louder the faster I went, but again only when I take my foot off the pedal. From time to time the whistle will stop on its own sometimes not.
After doing a little bit of research around various sites, I cleaned the throttle body as best I could without removing it. With no garage and the cold weather I am limited as to what I can do right now. I tried tightening the intake manifold which was another suggestion. I checked all the intake hoses and PVC valves on the crankcase. I tried playing with the air filter box, I have tried everything and cannot find where this is coming from and it’s really starting to drive me nuts. When I get out of my jeep and open the hood it can be a piercing sound. Has anyone experienced this before?
Again I only hear it when I take my foot off the gas pedal and sometimes it will go away, mostly when I come to a stop at a light or something. And it definitely seems to get louder the faster I go and then let off the gas.
Any Suggestions?
