MonkeyChap Posted May 21, 2020 Share Posted May 21, 2020 (edited) Morning, I brought this up a while ago, and got some really good suggestions about what might be going wrong. Basically, the car hunts at idle when cold. So much so that it will regularly stall when braking with the clutch down, and when sat at traffic lights. I've replaced the air bypass valve. I've warmed the engine up, bridged the idle contacts and set the idle screw. The problem still persists, and might even be a bit worse since I replaced the valve (with a brand new one). A while back I found a thread on one of the forums about early 3.2s having a different ECU map to the later ones, and the later maps causing this hunting problem (I now can't find the thread on google otherwise I'd link it). I currently have a later ECU in mine (courtesy of Sladey) and I wondered if that might be the problem. I also have a CANEMS ECU, but that has a single map in it, and I don't think there's an alternative. It is programmable though, so if I knew what to tweak, I could have a go. Anyone else had this problem ? Ta Ian Edited May 21, 2020 by MonkeyChap Link to comment Share on other sites More sharing options...
