Friend of mine has an 2000 Alero. That when you first start it cold. The Motor revs up. It shoots up to over 2000 RPM's and then after awhile 2- 5 Minutes it settles down to normal. Any Ideas? No engine light or codes. Sometimes the engine light will flash when going up a steep hill at highway speeds Then just today it started chugging like it had no power when you hit the gas in drive. Then came out of it. Ready to name this car Christine! Please help!

 

Flashing check engine light is a misfire, as far as high idle, I would check for vacuum leaks, possible IAC motor, or temp sensor.

 

Hello,
Check your power sterring fluid.

 

HUH???? Please tell me you're joking.
