Im having some trouble guys! I have a 07 350z hr, i installed some short ram intakes without the heat shields, and was getting to much hot air in and the car was going from 1 rpm to 500(below 1) and acted like it was gonna turn off wich it did when y came to a stop or light. When driving without stoping was good.i know installed the heat shields and the car now dosent turn off and does it a little less, check engine comes on. When a/c is on it does it a little more , what do you think!

 

1 rpm? That's awfully slow.

Sounds like your maf is all fcked up

 

If this was on the street and not the track, please try not to take anyone else with you when you slide through the pearly gates on your roof.

 

It stays at 1thousand rmp at the number one in the rpm gauge then it goes down to half (between 1 and 0) and then up again to 1 like in 3-4 seconds and it does that more when the a/c is on, it did it worse when it didn't have the intake heat shields on. Im really stressed, what do you think is going on!? Appreciate the info.

 

Read Phenom's post, sounds like your MAF. Also, you don't have to quote everything.

 

Ok thanks, how can i know wich maf? Or do i have yo change both!? Is it better to buy new or used! Thanks sorry for that. How can i post pics? Jaja im kind of new.

 

if you have an HR motor you have to check both MAF sensors to make sure they are good. You have two throttle bodies meaning you have two intake points, if im not mistaken the maf sensors should be where the intakes are.

 

Yes i know where they are, but how do i know if they are bad? And is it better to get new than used?

 

there is no way real way to check other than by 1. running a diagnostic on your car, 2. using a voltmeter to check the send and return voltages on your Maf, or 3. You can clean the MAF and run it around the block if you dont want to do either of those and see if your car returns to normal, but other than that those are your options

it is also better to buy new, you cant get MAFs for cheap from courtesyparts.com or z1motorsports.com

 

Thanks really appreciate it. Will look into that.

 

I can tell you're stressed. You quoted the wrong person in your reply.

 

Lol you didnt have to get him Flick, he is already worried about the car enough ahah

 

Not trying to be mean, just thought it was funny.

 

well considering it was an accident and i wasnt trying to do SIKK DRIFFTS like thanksgiving pole guy...
no ****. i went into a turn and slid out instead of slamming the brakes and spinning out i powered through it.

 

Always power out, bro.

 

Accident? Get thee to an HPDE!
