Where do I start.. the other day I noticed my car was idling a little rough. And all the sudden the check engine light comes on. so I take it to have the codes read and it gave me 5 different Codes.. First they said was the MAP sensor. The girl at AutoZone told me to just clean it this happens all the time so I did. After I started my car again it's now idling even rougher. And now the coolant fan does not shut off after I turn the car off for about 5 minutes it stays on. What is going on?? I've had no problems with this car! I will say I've used the air conditioner a lot because it's over 102° where I live in Northern California. If somebody could please give me some pointers and tell me what I should do.. My engine is shaking from the idling too high and why is the coolant fan staying on now? I need help as soon as possible I need my car to find a job!! Thank you in advance, Victoria.

 

The same thing is happening with my 2014 Chevy Cruze LTZ. Make sure you call gm and make a complaint about this! A month and a half ago, i just had my water pump, water outlet and thermostat changed in my coolant. I am currently at a Chevy dealership getting my reservoir replaced bc that is leaking now. It’s def not an cheap fix, and Chevy will only pay for the pump. This is a common thing to happen in Chevys, and it def needs looked into. It seems to happen a lot more right after the warranty is up, almost like a set up. Gm had told me the more people who call about this, the better the chance they will do a recall.

 

I work in over 110 and the fan is designed to stay on when the engine is in that hot environment to help cool the engine. The idle I would replace the spark plugs.
