well, finally it has happened, car broke down in Albany this morning, i think the MAF meter has dropped its bundle, the motor wont run, it fires up sometimes and goes for a few seconds then it seems to be starved of air, there is black smoke coming out of the exhaust, anyway i am taking a trailer down on saturday to pick it up, will look into it more when i get it back, this is the first time other than when i first bought the car that it has broken down, over 23,000 km i have done in it, still, it is a pisser
Even with the MAF diconnected it should start and run up to 2500rpm. The only MAF fault that make the car refuse to start would be it giving a max voltage signal and the injectors would essentially flood it with fuel. Try unplug the MAF and see if it will run in Limp home mode.
i am already at home, i hired a car, my car is at the exhaust place that i got to fit another pair of 12" hotdogs after getting a warning from the filth, i went to pick it up and it wouldn't start, had some problems getting going early this morning but eventually got it running, it ran fine for the 180km to albany then cut out about 1km from the exhaust place another half an hour to get it going again, but when i went to pick it up, no way it would run, it would start, just, run for a few seconds, give one rev then die cheers
mmm thats no good man, hope you sort it out... but on the other hand...good thing we all didnt risk driving across country.. lol the might TT's, im the only one that would have made it hahahaha oh the joys of being the meak!!
even new things break.... i just bought a brand new steam mop.... worked for 10 mins then stopped.. ok, i know... not the best example... but its true...
yeah and i cant start the day without a cigarette so using your logic perhaps his car just needs a smoke and it will be fine, seeing that a steam mop is now comparable with a ptu
i really don't think it's the ptu, it's more like a starving of fuel then an overload of fuel, hence the black smoke, when it fires it doesn't miss, runs smoothly other than what seems to be a fuel problem or air problem or both plus the fact that i dropped the maf sensor on to the concrete floor from about 3 feet probably hasn't helped much, this was after it wouldn't run though
Well... Black smoke is caused by unburnt fuel, not vice versa. And as others have said, the car will still run if MAF (AFM) is broken/faulty, but the ECU will detect the fault and limit your engine to rev out. do you have access to data scan? Blocked exhaust perhaps...
i said "then" not "than", what i meant was , when you first try to start it, it seems to be starving for fuel, then once it fires and gets some revs up it starts to blow black smoke, as if it is flooding, this all happens in a few seconds, like 10 seconds or so, yes i have datascan, but as this happened 180km from home i will have to wait till saturday when i get the car home to put it on datascan
i wouldn't have a clue how to check the error codes on the climate control pod, i have only ever used datascan
u havent tried sticking a paper clip in the consult plug? try it out and see. From there u can see what code it'll throw up. EDIT** try this
BHP same thing is happening to me atm This is what you do: Disconnect the AFM, and crank over for about 5mins until it starts....once is starts you will be able to drive normally but only until 2,500rpms. Anymore and the ecu cuts the fuel. When i connect my AFM i get the same stumbling and richness. When i dcc it drives normally until 2500rpm. Anyone know why this is? Usually when its raining or if the car is washed...on hot dry days no problem at all. It would be cool if i could do somthing to the AFM and fix it rather than buy a new one.
You can get this problem if the AFM is reporting an incorrect value to the ECU. It may not be recognising as faulty. If the value the ECU sees is incorrect, hence the mixture will be incorrect also. I can attest to this, as I had a blockage between my air filter and the mesh on the AFM (not important how that happened, but it did). The blockage was in the direct path of air over the hot wire. Now, although the car would idle and rev a little in the low ranges, if I made the attempt to drive normally, the car would backfire, blow shite loads of thick black smoke, and generally struggle to get to any decent speed. Since I have the convenience of datascan on demand, I was able to see the O2 sensors were not behaving normally, (Basically sitting on 1 and not moving) until I decelerated, then they would go to the other end of the scale. Checked the Air filter and presto problem found. So, although you may not have a blockage as I did, it is possible for the AFM to report an incorrect value and give similar symptoms without giving an error code. Swap in with a good known AFM to be sure, but as others have said, disconnect the plug, and see if you can rev cleanly to 2500rpm.
