This is just a quick response regarding codes P 0103 qnd P 0113 in that the MAF and IAT (Intake Air Thermomenter) are contained within the same unit so I'm wondering if the problem is the connector/cabling rather than the MAF and IAT?
It's a pity that you don't have a simple code reader to hand (probably half the price of one hour at the garage) - I seem to recall that the MAF/IAT codes 'latch in' - in other words, if you disconnected the MAF/IAT, the EML stays on even if plugged back in (am I right on this - anyone?).
Anyway,
@Stempyuno has just replaced his MAF so maybe he can tell you where to get one. If not
@BMR likely knows about these or a 'used' one from
@stevemen - both advertise in the trade section on this forum.
