All - I just bought a used 01 legacy sedan auto and a week into it noticed, while driving, it started sputtering/missing around 3500 rpm - 4500 rpm, as well as emit a high pitch type whistle from, what seems to be the rear of the vehicle/exhaust. this happens through every gear; 1, 2, 3 - have gone that fast in D. After the 4500 rpm mark - it smooths out until redline.
it has 150k on it.
just had timing belt, water pump, and head gasket replaced before I bought it. Seems as though it was also done at about 126k miles based on documentation in glove box.
so - did the guy who sold it to me actually do it - or am I a sucker - dont know - at this point - cant care - just need to fix the car and move on.
In park, the car will rev up to red line with no issues - aside form the whistle noise our of the rear end - so, it doesnt appear to be mechanical. It only makes the noise through that 3500 - 4500 range.
this started up two days ago - ive put about 50 miles on it since - seems to drive fine otherwise until today - check engine light came on. Last fill up was on Friday-check the cap.
I havent brought it in to check the code yet - just happened on my way home tonight.
Looking for a some guidance on what to check - used forums for my other soobies - seems to be the best place to get straight answers and willingness to figure it out with you.
Thanks for any leads - if you know a reputable mechanic in Omaha, NE area - let me know.
