Took new car out for a spin, was ok noticed a stutter around 2500 revs
Its an auto, kickdown now works well after cleaning MAP

came back put my hand held code reader and code 1638 was up, cleared it off again.

Any ideas anyone what causes this and is there a pointer as to where to fix, and would this cause the slight stuttering at low revs

Also the check engine light does not work but cars runs ok and is not in limp mode

cheers

 

Time to read up on the code then fix it. Clearing it is not a fix!!

 

Thanks for your reply I think

my post was directed at anyone who's had similar and fixed it as I where I might start to look etc
regards
