'99 vs statesman s/c v6 flat spot from idle

[pjdm1980]

Like i said in the title my S/C V6 Statesman has a flat spot from idle, it's had new O2 sensors, plugs, leads and a full service?
Any ideas would be really appreciated!!!!!

fuel filter or regulator or could be the actual fuel pump. probably at fault

Can't help with your problem, but thought i'd mention, finally someone has put a decent title which explains their problem!

Thanks!

forgot to mention that it run injected lpg and it had the flat spot before i had the lpg installed, flat spot on lpg and petrol

try cleaning MAF and TB it could be as easy as that mate.

Just rewired the earth for the 02 sensors and found that my ecu had been earthed before by the last people that had it! (Thanks ephect)

i removed all the codes it had code Code 76 - Air/Fuel ratio variation between left and right banks, so i'll replace the o2 sensors again next week.

I'll try cleaning MAF and TB tommorow. (Thanks blueV8vl)
