Engine Performance problem
1997 Chevy Cheyenne V8 Four Wheel Drive Automatic 248000 miles
My 1997 Chevy P/U looses power under load, like when I'm accelerating or climbing a hill. The problem first started when I replaced the vacuum idle motor. I've replaced the fuel and air filters. When it looses power the max speed I can get is 15mph. Putting it into neutral, the max rpm is 3000. When the vehicle is working right, the rpms will go to at least 5000. Help.
