Re: MG ZR 2.0 Td, 51 plate Archived Message Posted by Ian McCulloch on January 30, 2007, 12:29 am, in reply to "Re: MG ZR 2.0 Td, 51 plate" Try checking the voltage on the MAF signal wire going back to the ecu. Snap throttle and it should read close to 5 volts at its peak. Also bear in mind that unplugging MAF sensors, as above, will not always provide an improvement in performance. Some ecus, on Vauxhalls for example, see a fault with the MAF/IAT and just go into limp mode anyway, which could lead you to think that the sensor was not faulty. HTH, Ian.
