Hi I have a 2002 v6 and the light reduced engine power came on yesterday morning. So I turned the car off walked inside. Came back out turned it on light was gone drove it all day with no problems. Go to start it this morning it came back on couldn't go over 15 mph please help how do I fix it or what is the problem

 

Could be a number of things. Go to Autozone and have them scan (for free) your computer and see if there are any error codes stored.

 

yep get it scanned. low voltage will set it so check battery level.

 

i had this issue with a loose ground.. and then had it with a starter cable going bad. neither of these issues brought up codes for me on a scanner..
