Hello folks. I posted a problem I had with my idle on my lotus elise a couple of weeks ago. The problem was that the engine was ticking over high and when you lifted off the throttle after heavy acceleration the revs would rise before they would fall. So far i have changed the iacv, the throttle pot, the brown temp sensor, the plugs, leads, cap and rotor arm, checked for air leaks yet the problem still remains. I'm begining to think the ECU is at fault. Any more ideas again???
