Need some help peeps!
Start of the year i had a manual conversion done on my pfl saloon, since then my car has suffered from an irratic idle from a cold start.. after couple of minutes it was always alright.. but this may be down to using the lighter evo flywheel which is 6.5kg on mine (13 to 13.5lbs) but i doubt it as it is only on a cold start?? if it was the flywheel it would idle rough all the time wouldnt it? any ideas..
I changed the coolant temperature sensor, i tried a different MAF sensor, and i have just put a new Idle Stepper Motor on.. Going to see how this goes once its gone cold again. The Lambda sensor has also been changed now to Innovate LC-1 set up, however this was put on after the idle issue so its not that which is affecting it, however it does show that it can run to around 16afr on cold start??
When i was under the car for the first time since i noticed intercooler hose was loose on passenger side which may have had an effect? so i have tightened that up BUT i have noticed this hole which looks like its on the plastic pipe from the turbo's.. i don't know what this is im going to add a photo now if i can so people can tell me what itis, i don't think it should be left open like itis though!!
Once the car is warm the idle problem is fine and the afr reading does to 14 ish as you would expect, just want to know what your guys opinions are and any help would be much appreciated, Thanks =)
