Hi all,

Got a little problem this morning. Switch on the TR this morning, the rpm played between 500 & 100 rpm. Could not find out why. Called NRMA for an inspectionsion. After 5 minutes of checking here and there the guy pulled the cable connecting the air flow meter (AFM) box to the ECU (I guess that's were that cable goes). The engine stabilised immediately at 1000 rpm, as it used to.

Looks likethe air flow meter is at fault here. :rant:

First question: What are the risks associated with temporarily driving without the afm connected, until I bring it to the mechanic tomorrow?

Second: How much $$$ am I looking at here? :cry:

Third: If it's not the AFM, what else could t be? :doubt:

Thanks for your feedbacks...

I drove without it once, one trip i blew apart my muffler and used about half a tank over 20ks

woah man thats a bit insane..

when i went for a service at goodyear tyre n auto, they unplugged my MAS and forgot to re-connect it. When i got it back it was idling rough, and the feul efficiency dropped by 5-10%.. i was driving around for about 2 weeks like this..

other than that, i didnt have any majour problems.

jba: i wouldnt be too stressed about driving around without the mas, just dont doo it for too long. And yea definately have the mech check it out asap

There shouldn't be any major dramas with the MAF sensor unplugged. All it will do is the ECU will hop into failsafe mode to allow you to drive to places to get it fixed or whatnot.

Just wondering, did the Engine light turn on when you were having idling issues?

the air flow meter is a sensor that tells the ecu the amount and density of the air coming in, from their the ecu works with other sensors (knock sensor, coolant temp, etc) to work out the air fuel mix ratio, idle settings, and ignition timing. As a Mechanic i recomend not driving with it disconnected, if you can source a new one it is simple to fit. should'nt be to dear, at least its not a audi TT we change them all the time at work and they are $900, just go to a wrecker he probably won't know what it is anyway.

Thanks again...
