So I brought my car into lotus since it was still under warrenty. I was having a high idle problem at random times. cleaned TB changed MAF, have no codes so i figured let them deal with it. After all this time and them guessing its my ecu they sent it out to lotus to get checked and reflashed. I used to have koldfire 200 tune, but told them to just flash it back to stock. So as of right now they have been trying different softwear from lotus and as of right now the car will start and stall. They are getting a cam position sensor code. they told me it may not be the cam sensor it can be wireing or still a softwear problem. I dont get why it ran fine before i brought it to them besides the idle issue. Im a bit confused, any ideas guys?
