DIY Running problem help

Ok so its a 2003 cooper s, and clearly its something I have done, I got a good deal on an ITG panel filter and the samco intake hose to the airbox, so thought weather's nice today I will go out and fit it for her.
so very basic stuff this, removed existing hose and clips opened air box, replaced filter with ITG and replaced the hose with the Samco one including the small side air line half way along it, tightened everything back up with proper new hose clips that you can actually tighten as opposed to these horrible mini ones.
went to start the car, and the cel light is on, running and hunting like a bag of bolts and wont rev over around the 2k mark!!
WTF never seen this before with just replacing an air filter anyone any ideas?? I am guessing it's went in to limp mode for some reason so will need what ever faulty read or cleared, which I can do but does anyone have any idea why this has happened or been there?
where's the obd posrt?
thanks in advance!
Grant

Ok so just found the OBD port under the driver side dash, and just scanned the faults and this is what has come up! I have not cleared them as I really need to sort what ever is wrong first? unless it just needs cleared and end of? don't want to do anything really until I hear from someone in the know with these cars

P0123 Powertrain Throttle/Pedal position sensor/ switch A circuit high input

is the throttle position sensor the one at the bottom of the intake hose on the right hand side? as I did remove this sensor to fit the samco hose but then popped it back on and snapped it shut, do you think that could be the cause and if cleared would sort?

Hi ya

Sounds like you have knock something, there abit temperamental sometimes
Read your codes then Try a ECM reset any mod you do it's advisable to reset the ECM
Disconnect the battery neg first the poss leave for 20-30 min reconnect poss then neg.

Obd port is just around the brake pedal on the trim
If it is still there after doing a reset read the code and someone can help abit more

Can you post a pic
The only thing I can think is there is the throttle body electrical connector

These cars are very temperamental if your doing work on them with the battery connected, it can cause glitches sometimes if your pulling off plugs ect

yeah I never thought to disconnect the battery next to the air box and I just removed the sensor at the bottom right hand side of the intake hose, now I think about, after I had re-fitted everything I started the car with that connector still pulled out!! then I realised.
switched the car off and reconnected the sensor then started the car again thinking all would be well but still the same so read the above codes.

I can clear the faults using my reader would that not do the same as disconnecting the battery totally for 20-30 mins? it must be this that has caused it eh?

Hi ya

The ECM is adaptive so it learns how you drive temp loads ect
so it can learn your bad driving habits.
You have changed to a better air filter and inlet hose so flow will be different. So it's best to reset the ECM so start it learning again.
Your coder reader will only read clear codes unless you have the bmw dis software then you can clear all adaptations.

this is not our car but a quick picture I stole from the internet of another cooper 2003 s, and it was just the panel filter I replaced not an induction kit as in the picture but the sensor I am talking about is right under the hard plastic pipe that enters the lower air box I have circled where it would be in red, I am assuming this is the tps?

so do you think either just clear the faults with the reader and try to start again and see if tis sorted? or would you recommend disconnecting the battery as you say for 30 mins? will it make any difference? is the battery located in the boot somewhere never even thought of that

Personal I would read the codes see what they are fix or clear the fault.
Once your happy with it and all is ok reset the ECM :-)

It sounds like it's just gone abit cranky if clearing the code with your reader does not fix it do a ECM reset

Battery is in the boot under the Center panel just don't close the boot lid :-) or you will have to pop up the back seat to use the manual release

Like I say neg then poss to disconnect then poss then Neg to re connect or it will get cranky

Hi, your fault could be cause by the disconnect if the ignition on. But if you clear the fault code and try the battery re-set. If this dunst fix your fault. The next best move would be to
Refit your old unit before your fault started. And clear the faults and do another battery re-set.

If this clears the fault something with your new unit is causing problems with your air and fuel ratio.

If your have any more questions just mail me.
