The engine light and throttle light both came on, while I was driving. The temp gauge was on cold, really weird it is usually in the middle. I pulled over turned off car for about five minutes, restarted throttle light was off and engine light stayed on. The temperature gauge went up to middle between hot/cold. I am wondering if I should replace throttle body unit? And I have noticed the last month or so, when I step on accelerating to speed up, it sometimes holds back and then it will speed up. Kind of like choking, not sure if that is the right word. Sorry, I am a single parent; don't know much about mechanic. My go to help are these types of forum or Google. I appreciate any help!

See if you can rent a code reader or have someone scan it for you. Post the codes on here so we can try and figure this out and point you on the right direction. For throttle issues usually cleaning out the throttle helps a lot.

Hi ANNETTE1203,

If you decide you would like to conduct the scan yourself here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Hi, I got the codes they are P0325 Knock Sensor, P1281 Cooling system Performance and Bank 1. Are these major or minor problems? I really hope minor :) Thank you for your help!

I do not see no code P1281. But for cooling system performance codes usually low coolant will cause this. Check the water outlet housing for leaks. Very common failure on this cars. See image below. It is #1 Also water pump leaks. The water pump is behind the timing chain cover. There is a weep hole behind the A/C compressor. If you see coolant there it is going to be an expensive fix since the timing chain needs to be removed. Also inspect radiator and hoses. If all ok then the thermostat is faulty.

For the knock sensor code. The intake manifold needs to be removed. If the harness is ok then replacing the knock sensor should fix the problem.

The water pump and timing chain were replaced in April 2016. Could the thermostat cause this problem in the cooling system? Thanks for your help, really appreciate all your comments.

If there are no other leaks then a faulty thermostat will set a cooling system performance code. So replace thermostat, replace knock sensor if no damage to the knock sensor harness and clean the throttle body.

Hi, I got my car back and it is running great. The following parts were replaced regarding the problem I was having - Thermostat, Knock Sensor, my car was leaking fluid 2 days before I took it in, so the Radiator was also replaced. The mechanic found the following parts required attention and should be replaced as well; these part were replaced as well - Air intake manifold gasket and 6 spark plugs. I paid $611 for parts and labor. I am very happy and satisfied with the service and cost. :)
