new to the forum but have a problem with a pinin gdi
Hi all im new here but not new to forums, im a member of z22se.co.uk(vauxhall) and a few other vauxhall forums as i have had a few vauxhalls and still have my vectra.
but im here to find some help with my dads mitsubishi shogun pinin 2.0 gdi
it has decided to go into limp home mode so i plugged my diagnostic obd2 reader in and its coming up with p1221 so i googled that and some people are saying the throttle body will need cleaning out so i removed it and really cleaned it out with petrol and refitted it, removed the fault code and it ran ok and revved fine in neutral but when i drove it it was like it was coughing at lower revs but would rev through and be ok at higher revs but then as soon as I stopped at a junction it would start revving up on its own and then jump back into limp mode and wouldnt rev passed 2500 rpm again please help.
thanks in advance for any help cheers dave

Check the condition of the ignition system. Leads, plugs, etc. Then to a function check for them all and make sure you get a good strong spark for every cylinder. Then I would remove the injectors one by one, place the end in a bottle, and see if there's a weak injector.
Check your base timing too.

Hi thanks for the advise it had a service not long back so the plugs should be good still as they were iridium plugs
everythings pointing to the throttle body, iv read about some magnets that come loose and cause the throttle flap to become stiff to move and doesnt spring back and this is whats happened to mine so i think i will have to strip the trottle body down n look for these magnets
thanks again i will let you know what i find and maybe post some pictures

mitsubishi shogun pinin 2.0 gdi fault code p1221 throttle body fault
Hi all thanks for the advise but i have fixed the fault.
the fault code p1221 points to the throttle body but i couldn't find any concrete solutions so I will explain and add some videos and photos to help people in the future
the first step after plugging the obd2 reader in and getting the fault code p1221 is to remove the air intake pipe from the throttle body so you can see the throttle flap. try and move it, it should be springy both ways(trying to return to its original position if it doesn't the fault is quite simple and very cheap to fix(no more than £10, have a look at this video i found.
MAKE SURE YOU MARK THE THROTTLE POSITION SENSOR SO IT GOES BACK IN THE SAME PLACE YOU REMOVED IT FROM.
remove the throttle body and clean it(as it will be very coked up in there)
the video shows what is wrong but doesn't really explain how to fix it. you will see him pull the bar out with the 2 magnets attached then pull 1 of the magnets off. this needs to be cleaned and all the old glue removed so you can stick it back onto the bar i used apoxy resin upto 80 degrees but higher temp the better i would say, when you have glued it back on make sure you press it on firmly so its as close to the bar as possible, leave the bar away from the body for as long as possible I left it 24 hours to be safe to let the glue set, when you reassemble you will know that its fixed by the way it feels as it will be springy
when you have reassembled on the car and piped it back up it should run and drive as good as it did before the fault(if not better) but you may have to clear the fault code and maybe reposition the throttle position sensor but this is a easy job as it could have effected the tick over.
i hope that this is helpful to someone and if anybody needs any other help with this fault just let me know thanks dave

Good day
I am new to this group. I need some advise on my GDI Pinin 1800. I am from South Africa and nobody seems to be able to assist me?
The engine starts but idle irregular and shuts down at operating temprature. The scan show code 12? Should we replace the airflow sensor? Can I look somewhere else?
I have already replaced the throttle position sensor and another sensor and the CO2 sensor with no luck? I would appreciate it if any one can assist with some advice please.
Kind Regards
