Hi everyone. New guy from sweden. Hope that you can help me. I have 2 Micra K12. Both with problems. We start with Micra 1. It a manuell car and have lot of miles on it. I did get it because the owner did pay me with it for work on a another car. It have had very bad idle for a long time. It had the trottle body changed before in a try to solve the bad idle. I did ask around and the answer i get was replace the timing chain. Before that I did replace both the cam sensor and the crank sensor from the other Micra, but no change in idle. I then change the timing chain and it was bad. The tensior was all the way out. I also replace the the chain guides. Start the engine and the same bad idle, exept that same miss in timing. Did change to new spark plugs again, but same. I take the car on a spin and then after that I did read the foult codeP0011. Then I replace the cam senor to a new that I did buy before. Same bad Idle. Did read about some problen with debri at flywheel. Then I remember that the clucht was newly changed. Check every part of the flywheel but nothing wrong. Did take apart every kable conectors from the cam sensor, crank sensor, the conector behind the batteri and also the conectors to the ECM. I did se some braun stuff in the conector behind the batteri. Put on some 5/56 and clean everything. Start and the same poor idle exept I new foult code P1171. I did discover that the MAP sensor did have some oil on it after the chain change(sorry). Did clean it but same problem. I have forget to say same facts, that after the chain change it run on the higher idle that are then it is cold outside. Before the chain change it had problem to go on the highter idle. Also before the chain change it had no problem to rew up. Now than the P1171 it will miss and after a while it rew up. If I hold it on high rpm(3000) it have no foult code. I take my foot of the gas pedal and it go down and idle but soon it will drop in rpm and the foult lamp will glow. Read the P1171 twice in the foult reader. If I erase it will came back right away. The code P0011 can apear if I rew the enigine high. Try to check the harness but I can not find terminal 51 or 56 on the ECM terminal anywear. Anybody that know how to find it? And are that anyone that have had the same problem that I having? I have also tried to change trottle bodyies from the other Micra and that extra I do have, no change. Please help if you can. Nissan have give up.
