Just to reiterate. If you now have an early engine with an early head, 1997 and back, the plastic manifold will not fit. The first three flanges go the opposite way and the early heads do not have anywhere to fit studs for the first three upper flange position. So you are stuck with the alloy manifold. Sort out the senders and all should be well just leave the MAF and EGR modulator fitted. Disconnecting the MAF although it does nothing other than control EGR can cause the ECU to have a fit because it is expecting signals it is not getting. Good luck.Thanks Wammers. Yes I did read it, but I'd already paid for the other ECU. I'll get onto the other things this week. Fingers crossed for the weather.
