98.whistling noise?

1998 3.1
206,000 miles on it.
transmission rebulit about 25,000 miles ago,
about 1 year ago.
yesterday and again today from intial takeoff i noticed a whistling sound from about 20 mph up to about 40 mph.and it seemed to increase as i applied throttle.
is there some kind of vacuum to do with the choke maybe causing it?

Check all lines. There is one vac line at the top back, almost under the coilpacks, that is a very hard line to get on, and the vac line is almost too short from factory. I had a whistle there, took me a hour to figure out.

Re: 98.whistling noise?

Just came across this post and was wondering what the outcome was...any update?...whistling still there?

I have had a whistling noise since day one on a '95 I acquired about 5 years ago. Only audible at idle and through 1st and 2nd gear. Seems to be more noticeable under the car near the trans. Car runs great with no signs of a vacuum leak.

Re: 98.whistling noise?

I remember this for a hum-type "noise".......but you could hear it at idle.....start car and listen....shut off...disconnect vac line to f/p regulator and plug it....start car...is the "noise" gone? If yes, need a f/p regulator....

It was a strange noise, because it sounded like it was coming from everywhere when sitting in the car.....
