146ti flat-spot at 2000-3000rpm
Not an uncommon occurance, if what the search function threw up is anything to go by.
OK, between 2000rpm and 3000rpm the engine lack acceleration, feeling flat and hesitant. So far I've only noticed it whilst the engine is cold. I'd liken it to what a carb-equpied motorcycle feels like when accelerating whilst cold, when you've not given it enough choke. Starved of ful in a way. The idle seems fine, with with only a slight change in revs when the air-con, fan, lights etc are swithced on/off. From what I've read on here, am I right in thinking the lambda sensor is the most likely culprit?
