what is a good code reader for the 14 pin terrano

[dave123]

hi I just got the interface plug thing for the terrano to read the codes but the software the bloke sent me doesn't work so i'm trying to find something that works . I have downloaded ecu talk but that shows speedo graphs and my air flow is all over the place ( between 1.4 and 3.6 when ticking over . should it be steady because it says their are no faults . but the car still coughs and misfires when i'm pulling off more so when cold . I would get a garage to read them but no one around here the thing to do it and I don't want to spend £100 on the off chance

Hi i bought a OBD-II code reader from a well known Chinese site a couple of years ago.
It seems to do the job.Cost me about £60 at the time.I dont think your problem is the MAF.
More often than not if its MAF,the engine will not rev.
But i may be proved wrong

will a obd II fit on the 14 pin plug ? . also could it be the needle lift sensor on the no1 injector? without throwing up any codes

try unplugging the maf on tickover , or you could read the codes yourself :thumb2

The MAF reading should be steady at around 1.8~2.2V at idle, rising to around 4.5V in excess of 3500 RPM.
It should not be fluctuating, possible causes:
1) Faulty MAF
2) Bad or corroded connector
3) Broken wire
4) air leak in the induction path
5) Air filter not seated or loose
