Got yesterday exactly the same symptoms as described... not more not less... without any warnings after firing car up got impression I need to chase the engine in the garage... got some ride... no issues at rpm>1000... each time get car to stop as soon as reached ~idle started to shake and cel went in... could smell unburned fuel from exhaust... went back into garage and checked spar plugs... on the left side since access was easiest and my night time limited... plug the wire boots/tube out and found some oil... well... kind of spoon or two... since got no idea what to do with this just wiped that out... had a look into plug connector... clean that with air out of my lungs... plug that back in and fired it up... problem went away... really was under impression... still cannot believe got more luck then wisdom... yes... did not change spark plugs for awhile... so will do it anyway... other than that need to figured out where the oil came from...

thnx all for thoughts... I inspected all the air way to throttle plate, BTW replaced air filter, all seem to be OK. Found some oil deposit in intake manifold but that's another story... Will replace PCV valve... SuBrat84 could you give me more details about "some jingling noises come from a bad auto tranny before" i.e. how to link jingle sound to AT transmission possible problems... actually I can hear some little jinglings when putting some load... cannot specify where they're coming from... but got them for year... are kind of subtle and last for a while... never paid attention to that since car was running great... actually still is... only that acceleration whistle gets me worried... some little jingle have had always (since bougt that car), acceleration whistle that's something new... Will inspect my exhaust... and keep updating...

I've noticed in my 2001 OBW 2.5 L 4-cyl. AT some noise (rings/whistle) during acceleration. It comes from under the hood area. There's no such problem on idle. When driving problem appears (regardless of speed) in rpm range >3500 and <5000. What puzzles me when I keep pushing above 5000 rpm whistle goes away... No problem with acceleration and rpm <3500. When trying to keep rpm at steady 4000 in the "whistling area" whistle goes away. It comes back when trottling... Anyone has any idea where the issue could reside? Thnx in advance?
