XC90 Zavoli / Pan injectors Errors

hancym · Aug 27th, 2011, 09:18

I have a Zavoli system on my XC90 and it seems to recently be playing up and throwing error codes after a little as 100 miles. the mixture seems to contantly not be right when examined on the PC.

Having had it examined about 6 times now and re-tweaked, still cannot get it stabilised. We did suspect one of the Lambda sensors but having now run it on petrol for some time there is no problem.

Can anyone please tell me if the XC90 engine can go into and adaptive mode? For example if it generates an ECM code 2533 or 3503 would it then be tring to adjust itself as the range rover engine does?

What are the faults coming up? What engine do you have?

2004 T6 engine

Error 3503 and 3533, then it throws a P2177 (System Too Lean Off Idle Bank One) & 261A (Long Term Fuel Trim).

To eliminate and real problems with the car or the lamba sensors, I've run it for over 200 miles on petrol and no problems whatsoever.

What's the best spark plugs to run in a T6 LPG engine without going stupid on price?

The best plugs happen to be the cheapest. You want a single electrode plug - on your engine I think it will be the NGK BKR6ES

Your problems are with the LPG mapping. The map is not correct and need adjusting or there is an installation problem. Usualy an incorrectly mounted vaccum take off pipe of poorly positioned injector nozzles.

Do you know if the connected the OBD wires for the OBD mapping? Could be worth them connecting them up if not done or disconnect if they are connected.
