Hi, I'm fairly new to posting, have searched the forums for answers but get nothing specific so sorry if you have heard it all before:-

Got a stock R33 (Auto) Series1, have a 3" Exhaust from cat back, blow off valve and air pod. When I am at low revs around the street I accelerate, then let my foot off.....it then drops revs to about 500 and almost stalls, or it has even stalled once or twice which is not good. Any ideas? I tried putting a stronger earth for the fuel pump but no change.

Also driving at about 60km, the car sort or drops down then picks up then drops down, kinda like changing gears, but my foot isn't on the accelerator very much.

Hmmmm............

sounds like you might have a head gasket or dropped cylinder problem....get it pressure tested at a mechanics (in your capital city) and see what they say

another thing it could be is the air/fuel mix. If the Air Control Filter (which is electronically controlled) is acting up and not closing properly you will be getting air intake when your not supposed to and causing a drop in revs.....

also check the Oxygen sensor

I have this problem too.

You have to do 2 things to reduce the effects of this problem.

1) Clean the throttle body

2) Raise the idle RPM

Note that it doesn't get rid of it entirely. However the car becomes very much less prone for a stall after acceleration.

I have also heard replacing the AFM will also help.

      Another "where do these lines and plugs go" RB25DET question

      By thatjawncrazy · Posted

      GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Should have asked what is the car?

      Blue slip

      By PranK · Posted

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
