Engine Performance problem
1995 Toyota 4Runner 6 cyl Two Wheel Drive Automatic 265000 miles
My 4Runner has been running great since I bought it. Last night I came home and she was running perfect. An hour later I went to the store and it started up running extremely rough all the way up to 3000 rpm. It seemed to smooth out after reaching 30 mph. Today I popped the hood and can hear a vacuum leak but I also noticed the exhaust smelled really strong and white smoke was coming out. I checked the oil and it seems diluted and has tiny bubbles in it as well as being a murky reddish brown. Please help. I am on a very tight budget and work out of my truck. Thanks.
