2003 Mini Cooper s r53
140000 miles


I just replaced the clutch and flywheel with a Valeo kit. I did all the work myself but followed the video from mod mini to the T.
The car has also not been started in about 3 months.
the video is from startup and a brief run time, the engine revs very high during start up (I did not press the gas) and idles very rough and low rpm. 500 or so and bounces around. I have not driven it, only started it very briefly.

The codes I can pull are.
P1109- manifold air pressure too high in deceleration
P1242- secondary upstream manifold air pressure sensor to high in deceleration
P1689 electronic throttle control monitor level 2/3 torque calculation error
p0445 evaporative system leak detected (gross leak/ no flow.

My quick web search makes me believe that it might’ve an O2 sensor or MAF. But I’m not sure, any help would be greatly appreciated!

 

Do you have a service manual? If not, that would be my next step.

At a quick glance, I’d look for something left either unhooked or crossed up with something else.

Weird stuff can happen when you’ve been that far into your car. A long time ago, I helped a friend put a new clutch in his Mustang. Just before we fired it up I found the throw out bearing sitting on the bench next to my beer!🤬
