Just thought I would share this, it may help someone with a similar problem one day.

 

My Z32 was doing mid-130's at the time (someone else driving of course?!) and the engine missed a heartbeat, then another and another and then the revs started dropping quite rapidly.

 

After pulling over, it stalled but started again. It would drive up to about 2,500rpm but not over, i.e. sounded like it was rev-limited.

 

Finally got back home and turned to the internet thinking it was a sensor, CTS perhaps, or MAF. I opened the passenger footwell cover and put the engine diag. into Aux mode and saw that the car reported that it was the MAF sensor which is likely to be playing up.

 

So, I reset the diag and tried again and the same diagnosis. So I pulled the MAF and after cleaning, it looked like everything was in order to me, so I put it back. The engine run fine until warm and then the same problems struck again. But this time, I distinctly thought that it was better than before, especially on a steady idle.

 

After searching around the internet for a while, I saw that others had sprayed the little transistor/resistors inside the MAF sensor opening (from the back and from the front) with a carburettor cleaner that disintegrates fine dirt (that cost just £3 by the way). I did that a few times actually, and tried cleaning it carefully with some tissue.

 

Put the whole thing back together and hey presto, the car has been faultless (engine wise) since and idles and runs much better than it ever did.

 

I'm sure that the vast majority on this forum know this already, but thought I would share it for those who didn't.

 

Happy flying...:hyper:

GREAT TIP!:hyper:

 

dan.:D

electrical contact cleaner is great too, sprays a lot in one go+ after its washed the dirt off, dries with no residue.
