    Just playing about with my vcds and i seen that it says (0.0 BTDC) in the engine messuring block!
    also it says 455.0 mg/str on the mas air flow (actual) But it says it should be between 180.0-300.0 mg/str! Is that right? If so could my maf be playing up? My idle isnt allways smooth! Sometimes it jumps now and then a little! And you can see the rpm needle moving up and down about a mm When idleing!

    Was the car up to full running temp (oil not water) if not you won't get a true reading.

    The idle is ajusted to 820 rpm to help with vibration! Also i dont think the car was upto temp! Will warm it up and try again! Thanks

    Either his full stop key has broken or someone didn't pay attention at school.

    Either way, how different we're your readings once it had warmed up?
