Im in the right place then. Thanks for the reply. Like i said I have the equipment to tune my car now all i have to do is learn a lot!!!! I have been doing some data logging with EEhack , I am currently stumped on a huge blm split on the right bank as soon as car goes into closed loop right bank shoots all the way to 160 at idle left bank is super close to 128. my car is basicly brand new front to back, so im leaning towards a vacuum leak. I am going to buy some carb cleaner and spray around some areas to see if i get any idle change.
