I am having problems with my car idling high.Rpms go up to 5000.You can hear the engine revving real loud.When I try to brake the car jumps forward and is having trouble coming to a stop.I went to autozone and the code came up p2074.What does it mean and how can I fix it?

 

sounds to me like a bad vaccuum leak. read on another page that that code means a big vaccuum leak. check all the plastic hoses that run from the engine and airbox and whatnot for wear holes or even cracks. if thats all it is it will be a simple fix, hope this helps

 

Vacuum leak. Be sure to check the PCV line; that is the big one.

 

check that breather tube for splits as well

 

could be a throttle body problem i would check and see if it has any holes or if the connection is tight

 

Mine did somewhat the same thing and I had a vac leak rpms didn't jump as high but the vac elbow that come out of the tb is what caused it

 

Does the brake pedal feel hard?

 

I changed my starter and front break pad and after that I am getting the title mentioned code. Please advice. Thanks

 

Check to make sure you reconnected all the vacuum hoses(specifically the one that connects directly to the intake manifold and valve cover since thats in the path of working on the starter) make sure none of them have any small holes or cracks in the connectors

 

Did you remove the intake manifold to replace the starter?
