P0121

Car runs spot on, starts absolutely fine and idols bang on. Finished work the other day, started her up and the engine management light came on and stayed on.

Pulled the code from it and got P0121 after googling it could be a couple of things from accelerator pedal, throttle body cocked up or a throttle body sensor. Or even the wiring I.e corrosion etc.

Cleared the code today and took it for a 6mile (ish) blast and it hasn't came back on as of yet.

I know it's a guessing game but anyone any experience, reckon I should just wait and see if it comes back and stop worrying.

I'd probably wait for it to come back again... if you go changing parts and it never comes back, you'll always be wondering if what you changed fixed it.

Well it was fine all afternoon yesterday, fine on the way to work this morning. Started her up when I had finished work and the eml came on again so its obviously the p0121 code again
