I have a 1990 Chev Corsica. As of about a week ago, the brakes totally starting squealling (but feel totally fine). The strange part is that the squealing noise also happens intermittently just while I'm driving (i.e. often turning a corner) even when I 'don't' have the brakes applied. Could this problem be the brakes.......even though the squealing noise often happens even when I'm not using the brakes? I'm debating whether or not to fix the problem, or just buy a different car. I've spent $800 or so in the last six months on the Corsica and honestly, the car's just not worth it. I guess I hold onto it because I fear that buying another used vehicle could bring me even more problems than I presently have... Any advice? Thanks.

My check engine light came on a little while ago while I was driving and my jeep started acting sluggish. It bucked a little bit at first and now isn't idling right. When I push the gas it's not reving like it should. There seems to be a slight delay. Then it acts sluggish. I am about to take it to Auto Zone and have it tested so I will be able to post a number in a few. Any ideas in the meantime of what it could be? I have a 99 jeep wrangler sport, 82K miles, 4.0 engine. Thanks.
