Hi, i recently fitted a lupo sport inlet manifold and throttle body to my 1.4s but ive had problems with the car such as rough idling. The car sounds as if its cammed when at idle. On occasion the car will also cut revs and wont rev at all, i do have engine codes and i have checked them, it says P0106 - MAP/Barometric Pressure Circuit Range/Performance Problem It also says fuel bank trim 1, i have replaced the map sensor but did not fix the problem. The car is fitted with a gti throttle body which has extra vacuum pipes that don't connect up to my engine. I was wondering if it was just a case of there not being enough fuel and that it just needs mapping but am unsure if it is something else. Does anyone have any ideas to what it could be?
So some may remember I had the issue with the car not starting atall and vagcom have me loads of codes and none helped point me in the direction that wires had become loose lol but one of the codes was about the O2 sensor. Now the wirings all fixed and car starts... Usually! If I leave her in the sun and the car heats up the engine won't fire in just turns over, and like last night I can literally be stuck for 3 hours waiting for it to cool down. Also happens of I get fuel for example and when I got to start it back up because its warm it won't start and have to wait for it to cool down again! I had a problem with the oil breather as it was overly clogged and smoking like a trooper, however that's been cleaned out and still having the issue, also the temp gauge is iffy but being a normal lupo fault I've over looked this, if I stop at lights or something ill notice the temp has dropped right to the bottom then ill start driving again and it'll come back up to the middle. I'm waiting to get it plugged in again but may be a few weeks, any ideas? I've been thinking 02 sensor but starting to doubt myself!
