i have 07Z and its bogging between 1.5k rpm and 2.5k rpm.(no cel light) problem is... car doesnt bog all the time (it bogs on any gear, even 6th)
I have taken my Z to dealership and didn't find anything wrong with it.
what should i do????

this is what i have on my car
18x9.5 Rota Torque wheels
Tokico D-spec
(spring/adjustable Shock kit)
Tanabe Touring Medallion Exhaust

 

exhaust leak causing a/f problem maybe.

 

mind if i ask you whats a/f?

 

air/fuel ratio(oxygen sensor etc)

 

is your car standard, maybe you dont know how to drive stick. IDK

 

if its a certain rpm in any gear my guess would be the throttle position sensor

 

The exhaust leak would have to be huge for this to happen. Maybe one of your o2's went out, or maybe you have a disconnected vacuum line somewhere. It's strange than the dealer couldn't find anything...

 

i think i might be having a similar problem but its only when i crank the car. the car will bog down and almost cut off but i give it a little gas and its ok. i think it might be the intake cause its not the stock intake but idk maybe not getting enough air, maybe its the same problem but mine doesnt do it when i drive.

 

what rpm does your car bog at? cold start? whenever you drive? when does your car bog? mine seems to only bog when its colder....when its fairly warmed up it does not bog.

the guy that said its my driving....its not. ive had several people drive it saying the same thing. when you drive it hard it doesnt seem to bog, or at least its not as noticeable.

dealership said plugs and injectors are good....actually they said the car checked out and nothings wrong, but its still bogging. i wish i had a honda....a prelude.....a white one...with a silver hood....sooooo fukin sexy....gosh....i just nutted my pants.....BONER!!! 8==========D

 

no mine only bogs down when i turn the car on and it will drop below like .5k rpm and almost cut off and then it will jump back up to about 1k rpm and be fine. It never does it when its cold when i start it up in the morning its more like after i drive for a while and its warmed up and then cut the car off and turn it back on warmed up it will do it and not all the time either its wierd. but they say everything is good lol, i think i just need a tune, it never does it when i drive either...so idk im just saying i think i might have a similar problem, let me know if you find out what the problem is

 

my car is fine when its cold and then after its all warmed up it idles around 750rpm and starts to bog down. But if I turn the air on it wont do it cause its idling a little higher like around 800 to 850rpm. does anyone have any suggestion on what it could be?

 

How long has it been doing it? Might be bad gas. I used to get gas at the station across the street from me and had startup problems. I checked everything took off my maf, throttle bodies, intakes, manifold, and cleaned them. changed plugs everything I could think of. But no luck. Bought a can of octane booster and got different gas, haven't had the problem since. It was an expensive lesson but i learned not all premium gas is the same.

 

I'll try a different gas station. I never noticed it until I moved away from the gas station that I used to use. I always go to this different gas station now that its on my way to work. I'll try some octane booster too and i'll let u kno if it fixes my problem. I changed the plugs a couple months ago so they should be fine.
