it looks like english, but somehow i cant understand it.

 

idle will speed up and down when running when engine at temp idles fine cold hope this helps thanks all idle speed sensor maybe dont know thanks all

 

Will you use periods and commas please? Cant understand a damn thing your trying to say

 

sorry my engines idle, will drop and go back normal when car is at a stop light. it like a govner on a lawn mower. sorry if i offended anyone

 

For a start, clean your maf and throttle body. Then a full ECU Reset. How many miles on your car?

 

102,000, just bought it. this is the only problem i have. runs great. lots of extras. ACM cold air intake. hope this helps more. thanks for any help

 

how do you do a full ecu reset? will unpluging the battery do it? my first Z

 

dont you mean AEM intake? For the reset, you can do a "soft reset". Unplug the negative battery terminal and hold down the brake for 5 minutes and that will reset the ECU.

 

yes AEM sorry finger slipped. thanks for your help!!!!!

 

Thats like saying unplug the negative battery terminal and hold your finger on your nose for 5 minutes. If there's no ground the ECU is getting no power therefore it will reset, no need to push any pedals.

 

lol at the brake hold

 

Mass Air Flow Sensor(MAS)

Putting finger on nose helps

 

I think I'm having the same issues as this guy but its hard to understand what he is saying so idk.

*was this problem fixed? And how?**


My problem- when I have my vehicle in neutral idle is steady around 1000RPMS. when I'm driving the vehicle and throttling it hard and take it out of gear, it will drop to 500rpms then stall. It doesn't do it all the time.

Any input?


I got a 03 350z. 113k on it.

 

I had a similar problem before. Cleaning the mass air flow sensor, and cleaning the throttle body solved it for me.

 

Did you remove the parts and cleaned it or did you use a additive in the gas?

 

I’m having this exact same issue on my 04’ 350z. My car will idle roughly at around 500-700 rpms then sometimes just turn off in neutral. It even turned off when I put it in neutral going 50 mph. I’ve replaced both camshaft position sensors since it threw me a code about 3 weeks ago. But this issue remains. Any ideas on what it could be? No check engine light has shown itself. I’m thinking something electrical? Or maybe not enough air flow? Any help would be greatly appreciated!
Mods:
no brand cold air intake
greddy exhaust system
