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.
have the same problem?
