    Hi Geoff , I want to help you with your question, but I need more information from you. Can you please add details in the comment box? What size motor and the squealing does it sound like the belt. Or was it coming out of the throttlebody

Sounds as if you may have a vacuum leak. Use a length of hose with one end in your ear and the other move around under hood to help locate the sound. BE CAREFUL TO AVOID SPINNING FAN AND OTHER OBJECTS. I ASSUME NO RESPONSIBILITY FOR THIS PROCEDURE.

SOURCE: RPM issue when accelerating

Is this an automatic transmission or a manual shift?
If manual shift,you have a clutch slipping problem.
If automatic,you still have a slipping problem.

SOURCE: I have a 2003 Jeep Wrangler that has a high pitch SQUEALING sound when I release the accelerator. Any ideas what's causing it or how to fix it?.

I know i have the same problem, and i also noticed than when i open the Hood the whistle just stops, so i figure out it must be some air cycling in or out osmewhere, I found out my air intake connected to throttle body was misplaced a weird gap was left open allowing air to whistle. u might wanna check there

It could be a vacuum leak on the inlet manifold or pipes Start engine and allow it to idle, spray some wd 40 or similar around the inlet manifold & vacuum pipes, if you notice a change in engine speed when you spray you will have found the area of the leak

Power (acceleration) loss at mid-high RPM only


Loss of acceleration, the backpressure noise and such are kinda tell tale signs of that converter having problems, feel the exhaust out of the tailpipe it will be warm normally have someone step on the gas and if its super hot it'd be a step in the right direction.

Power loss + squeal @ 4500~ rpm


Could be the cat, They can make some pretty strange noises...Disconnect it and take it for a short ride and see if rpm's are fine (with it removed you probably won't be able to hear the noise though)

1998 Subaru Outback Wagon Grinding Noise/Squeaky Brake/Gas Gauge


The first issue, I would have the brake calipers checked for either a pin stuck or one of the pistons stuck, It is a dual piston caliper and sometimes one will stick causing pad to angle slightly. While inspecting the brake issue also check your wheel bearings, which may be the squeak. On the fuel issue, I will tell you a secret, LOL, but Subaru has set the fuel gauge to read E but still have about 5 gallons of fuel left. I use US measurements, but trying to use my head I believe you are getting about 22-24 MPG from what you said and that is pretty good. I hope this helps a bit and have a great day.

High pitched squeal in engine


loose fan belt?

Put the car in neutral, set the parking brake, open the hood, get someone to listen/see where the sound is coming from, as you press on the accelerator.
