Hi there,

I just recently bought a Takeda Cold Air Intake and Catalytic Converter back Straight Pipe Exhaust. I`ve been driving on both for about a month now and 2 weeks into installing my Cold air intake the engine light came on. I checked the code with a OBD 2 reader and it says its burning too lean.

So my question is do I have to get the ECU reflashed and tuned or is it something I did while installing the CAI..

Also is anyone else experiencing this as well..

someone else had trouble with a takeda CAI, something to do with the MAF housing being wrong from memory, Dora Anne.

weekends are a bit quiet mate, wait till monday, someone will know more or u could PM dora.

or search for the thread

if it is too lean then thats the exhaust im pretty sure
when you had the cai did you flog it after you installed it or let it idle for like 10min and then drive nicely
could also be the reason
but if the error is too lean then that is your exhaust

running lean means that there is something causing the car to not inject the right amount of fuel to achieve the correct burn ration. this can be caused by two things, the Precat Oxygen sensor in the exhaust this would cause the car to run rich, or the Air Flow sensor in the intake reading the incorrect amount of air causing the engine to run lean or rich. given the engine is running lean i would say its the intake.

check all the clamps and joints on the piping as any air getting into the intake after the sensor will cause a lean condition. if that doesnt help it may be that the pipe where the air flow sensor is located is not the same size as stock, or the air flow sensor is not the same depth as stock into the pipe. this will also cause a lean condition.
