INFO is KING !!!! so more please, what year is it, what engine size etc etc
Your code I think relates to Oxygen sensor, so ask them to check that !
OH, and welcome to the Forum
fault sounds familiar beleive this fault relates to the electric throtle pedle just a thought but if you take out the glove box there should be a four pin black connector that looks like the one ontop of the throtlle pedle chop off the plug and chuck it in the bin , but make sure you connect the wires back in the right order or you will need a complete harness front to back and it aint cheap, and its a v v v big job to change hope this helps
i renewed the unit and everything ok.
mind you still got the surging problem when cold it's has had from new. i dont know what this it, its had the update.
all i have done is clear code and will use it a little while see if i can get the problem back on.
the coed is P1161 THROTTLE POSITION COPY. dont know what it means.
this car had a new throttle body on 6000 miles ago.
i know of another C3 that had had 2 throttle body on in 10k. Could be a problem eh?
Try using the BBA Forum search button above i,m 99% certain i have posted on this before.
P1161 is a throttle cohearance code.
