For the past couple of months my car, Volvo with 95 1UZFE and w58, has been sitting around whilst I've attended to other things but I have recently started using it again as the weathers improved. Thing is, before I let it sit idle it was smooth as anything to drive from low idle speeds right up to its redline, but now it doesn't want to idle along smoothly in any gear below 2000rpm.
This first started with a reluctance to cruise in 5th at 60kph then it got worse to where taking off became difficult unless I kept the revs above 2000rpm. Think back to when you drove a car with a carburettor with no choke, first thing in the morning. That's what this feels like, however it idles without a problem.
Anyway, I disconnected the battery for 30 sec to get the ecu to reset, and the problem went away but after 3 or 4 starts the problem reappeared. A further disconnection of 12 hours also had the same short term fix. The only fault codes I get are for the sub oxygen sensors (not fitted) and the speed sensor (also not fitted) but these have always been there since the conversion 18 months ago. My guess is the ecu is playing up but is there anything else I should check that might be causing this problem.
