okay had my injectors on my cav turbo ultrasonically cleaned, new fuel filter, new plugs gapped at 0.7mm car idles bang on none of this low and high idling so im presuming inlet gasket is fine, pressed fuel nipple and fuel passed past my shoulder so i presume fuel pressure is fine but i will still get it properly checked.
can aduff head gasket cause a car to run lean.
the car took approx 12 mins to go from cold to normal temp at idle is that normal or getting warm to quick.
also what colour should the plugs be if the car is running lean as they look a little yellow sand type colour and show as small crusts.
final option duff air flow meter and its brand new, sport comp type.
