Having fixed so many thing since buying this CTT there still remains weird running. If cold the car runs good no stutter but as soon as it's warmed up it misfires through 1k-3k rpm and then clears to redline nicely. After replacing bank1 precat lambda sensor I'm now happy with the graph data from the lambda sensors. So this doesn't look like a lambda sensor open loop vs closed loop situation causing the misfire when warm. The car is very temperamental for no apparent reason. But if I do the throttle body reset (key on pedal down for 5 second, key off, then key on wait for 60secs the key off, then start engine it really does change how the car behaves! The stuuter kangaroo is still there but much less and throttle response is back to something expected. To accompany this temperamental performance is a high pitched whine from the throttle body/ inlet manifold area and jerky peaky gear shifts. The DC motor controlling the throttle butterfly can cause problems I've read, I checked the potentiometer readings and plotted on graph and they look fine no jumps or gaps in the resistance reading of the opposing scales. Did the adaption also it works fine and has adapt value of 11 when finished. Is 11 correct or a high value? I'm considering removing the throttle body and stripping it down but it's a delicate piece of equipment and I don't want to bugger it up. Any advice diy or repairs anyone has done to fix their throttle body??
