I heard a guy name anil is good at these issues anyone has a contact for him?



dont just only check vacuum hoses for leaks you could also have a faulty intake gasket which is not sealing properly and could be introducing the extra air into the system causing the rough idle...

check your intake gaskets and such - spray the general area when the car is ruing with carb cleaner and see if the idle improves - spray to much and you may stall out the engine -- which is expected if the gasket is bad - be warned - carb cleaner on a hot engine can cause a fire -- so have your fire extinguisher on hand

the person you referring to is anil sooknanan. do a search on his name his # will show up.

My almera was doing the same...took it by him...he scanned the car ...picked up nothin...he didnt have a clue....so good luck with that.....

I eventually swapped my brain box after everything i tried fail....lo and behold the car was back to its sweet self as soon as i plugged in the other brain box....

All kinda stupid things mechs made me do...like cutting out my catalyic converter etc

I know your issue may be different but swapping the brain box solved my prob
