My 07 automatic touring roadster has a weird issue...runs great all the time except when I stop and hit idle rpms...then the tach is jumpy and if I don't give it enough throttle when starting off it will hesitate or even occasionally stall...once I'm at higher rpms there are no issues...seems to only have a problem at idle rpms.
Basically, if i give it enough throttle it seems to overcome the issue but if I give it gradual throttle it wants to sputter or stall...any advice greatly appreciated!

 

did you read "service engine soon" codes with a scanner if any? other than that i would think this looks like a VSV solenoid problem. always check for codes.

 

The check engine light is not lit...
Can you explain the vsv problem?
Thanks!

the VSV is the "Vapor Canister Purge Volume Control Solenoid" or something like that(big name), at least in earlier models its part number is a83-600. basically if it screws up, it may make the car not hold the idle or make it "jumpy". weird thing is they usually make the SES light go on, when they have problems.
