Help, car is stalling when lifting off throttle
Hi,
I have an EVO 5 with rebuilt engine incl. everything; pistons, rods, JUN 264 cams, autronic ECU, greddy t67 turbo, etc.
Car is mapped on rolling road and made some pretty OK figures. It makes -0,3 bar vacuum @ idle with fans on, the problem is that when driving the car and lifting off throttle the car stalls, any ideas would be highly appreciated!
What could cause the stalling? Idle control valve runs on 100% and the idle can not be adjusted higher than 1100 rpm in any way.
Car starts fine and runs pretty ok on idle except in the scenario above when lifting off throttle.
Thanks
