Update on air flow problem.

Hi Guys,

 

Put up a post the other day about my 02 sensor and airflow problem but have since resolved my o2 problem.

 

I have an airflow problem where when I start my car the rev counter hovers around 1000 - 1500 then after a while drops back down to 750 but will then flicker up and down and you can here it popping.

 

Also when i hit 3000 revs the car suddenly kicks in and its like a turbo lag so I took the air fliter off as I have an induction kit instead of a standard filer and had a drive and it worked fine when i hit 3000 revs so no sudden jump. However when I parked the car it died on me so i put the air filter back on and the car started fine.

 

I am probably right in saying that I have an airflow problem where there isn't enough air going through so has anyone else had this prbolem or can advise what might be causing it?

 

I am going to take it to a nissan garage but if anyone might be able to offer any adivse I would be really grateful.

Also thought I'd mention I have no cats on the car but I'm assuming this would not be effecting the airflow problem?

 

thanks in advance.

I can not offer you any " adivse" however i would recommend that you take your car to a 350Z specialist instead of a Nissan dealership.

 

Where are you based and perhaps we can point you in the right direction.

I'm based in barnstaple north devon, I gave taken it to a garage already but a couple of mates have suggested I take it to the Nissan garage as they would probably be able to identify the problem?

it does sound like posibly a faulty MAF sensor, but get it looked at by someone in the know as its a bit of a stab other wise

 

I've been trying to gain as much info as I can as It does sound like a faulty maf sensor. Have read on numerous forums that when you change your 02 sensor then you may have to change the maf sensor too.

Have you checked the rest of the piping for leaks / loose connections? had a similar jump experience once when a connection was loose.

 

I've already had it in a garage and they didnt find anything, because I changed a 02 sensor they reset the ecu and took off the engine light, it did do the Job for about a mile then engine light came back on and in the morning when I started her up she was doing the flickering on the revs again and making a popping sound

With it popping back it sounds like an air leek check nothing is pinched and that its all seated good.Have you got anyone with a Z near you, if so fit there Maff to your car and try that if it works you know it's the Maff.

I don't know any z owners nearby me I'm afraid. I have been on the phone to a friend of mine today and he also pointed out that when I drove the car without the air filter on I didn't get the popping so it might be worth replacing the air filter too as its not a standard airbox filter.

I wouldnt be driving the car with no filter on. You could suck up anything causing all kinds of very expensive damage

 

I totally agree with you but I had to check to see if it was the air filter that was causing the problem so won't be going it again.
