300ZX DRIFTER

Update for the rpm symptoms. The revs will go all the way now but when I reach full boost the throttle cuts off and then I need to move my foot of the pedal and depress to accelerate. The problem started to happen after my car come out of the garage. I had two 02 sensors and a maf fitted. Any ideas?

I have a new one fitted, starts and drives like a dream but just cuts out around 4000rpm. It's not an original one, aftermarket maf. Do you think this is why it is cutting out? I was told to tune the engine once the maf was installed. What part and how will it be tuned?

My ZX is running much better after changing the maf and two o2 sensors. The only problem is when I step on it, around 4000rpm it will drop right down as if there is no gas. I then depress the pedal and she drives fine, as if I am driving a manual car. The engineer could not find a fault when he connected the ZX to his diagnostics device. He said maybe the spark plugs need changing. Any ideas?

The car has passed it's mot after changing the maf and two o2 sensors. She drives fine now but when I step on it, around 4000rpm it will drop right down as if there is no gas. I then depress the pedal and she drives fine, as if I am driving a manual car. The engineer could not find a fault when he connected the ZX to his pc. He said maybe the spark plugs need changing. Any ideas?

Failed it's mot on front discs and pads. Regarding the rpm not going past 2500, could not test the emissions. My local garage said it is the maf, waiting for new one to arrive. Will update you guys when the problem is solved.

Thanks a lot lads. Will clean the MAF and see how I get on. Cheers Dil...

My Z32 will not pass 2500 rpm, and on very low fuel it can cut out around corners. The funny thing is that my car cut out on the same bend on different days 3 times. I have changed the fuel filter but had no luck. Do you think it may be the air flow meter? Regards Dil

Was wondering if this was normal. My 300ZX twin turbo does around 22mpg on the mototway and around 13mpg in town doing short journey's. I have an air fuel ratio gauge installed and gives a reading just over the rich point when in town and not so rich on the motorway. The 02 sensors are OEM not wideband. Any suggestions.

Cool mate. First need to take the plastic panel off to get to the relay. Where did you start from?

Thank you for your help. Good day.

Thanks for responding mate. Gona buy an aftermarket boot switch. Did you manage to get to the relay with ease?

Little confused with the boot switch. I cut the wire and the end from the switch is negative but the other end that connects to the interior and boot light reads positive. Thats why my alarms door trigger feature was not working. I have connected the alarms wire directly to the boot switch without the wire from the interior light and the alarm worked fine. Any one had this problem?

Probably that's why my alarm is not activating as it should.

Does anyone know if the boot switch is a ground or positive type swich. Connected it to my alarm which needs a ground signal for the door open feature. The alarm is not responding when it's armed and i open the boot or doors. Any ideas?

Cool, that sounds good mate. Will do the installation tomorrow.
