Vacuum leak?

 

Enter diagnostics and write down all fault codes and whether they are current or history. sometimes after reconnecting a battery, the engine must re learn the idle which could account for the hi RPM on restart.

 

Thanks all the acclorator sensor went out ,replaced works great. Thanks again
