Getting boost in neutral

[Rowdyr32]

My car won't rev above 3000rpm and is creating boost in neutral above around 1500rpm. It's running realy rich at the moment and my only mod is a front mount intercooler and the pipes aren't leaking.

I was wondering if it could be the O2 sensor because in fluctuates between .5 - .8 volts at idle even thou it's running rich.

How can I test the airflow meter.

Any help would be much appreciated.

try unplugging the AFM and see if the symptoms change...

if its the same, your AFM is likely dead/almost dead, try borrow

another to test. also try clean the plug connections etc.

FOUND THE PROBLEM (I hope)

After I changed the cam belt I thought I wouldn't put the dust cover back on to see if the belt stayed tight. At the time I didn't know there were spacers in the cover to space out the crank angle sensor. I drove the car around the block and is stoped. Towed it home. Have been driving it around for about a week now and the above problems occured in the message above. Just checked the timing and it was really retarded(would only just idle). Pulled apart the crank angle sensor and the input shaft was snapped. An expensive mistake to make.

*Please note to anybody thinking of removing the cam belt cover you need to put spacers between the sensor and the cam gear if you leave the cover off.

DOH

Glad to see you got it sorted.

very lucky it didnt snap the key in the camshaft itself

I made the same mistake myself, wondered why the car seemed so flat and lifeless, the CAS was fully retarded due to not having the spacers. Felt like a dick-head when my tuner told me.

You live and learn.
