Rb26 Stalling

[stagea_1998]

Hey guys

Having a slight issue with my 260rs stagea

just whenever im driving and im at say 3000 rpm or upwards

if I clutch in to slow down (so the revs drop quickly) the engine cuts out and stalls

but if I engine brake and bring the revs down gradually there's no issue at all

any ideas??

Thanks guys

Do you have an atmo bov?

[stagea_1998]

Nah man full recirc

So we can cross that one off the list.... got me stumped though

checked AFMs?

[stagea_1998]

yea i already tried 2 known working afms with no difference =/

other thing i noticed yesterday is ive got oil spray that looks to be coming out of my dipstick tube, which ive nailed down to bad PCV valve

im going to change the PCV valve anyway but do you think that could have something to do with it?

Is it recirculating back to your intake?

[stagea_1998]

Yea its still on the factory set up so recirculates back to just before the turbos

I've already tried a pair of new bovs (26's have 2) with no difference

But its more related to rpm that boost pressure

example if im just rolling at 4k rpm, so im on vacuum it will still stall out if I clutch in or shift to neutral =/

Have u cleaned ur aac? Sometimes the solinoid sticks and doesnt open the air valve. Easy way ro check is on idle unplug it and if it drops off u have found ur cause. Could also be the tps not telling the computer that the throttle is closed. Basicly an on and off switch.

I got the same problem with r33 (rb25det)... Using my ecru software I monitored the car when it does it and the voltage readings drop to low 13's.

boom! simple as that got it sorted by the looks of things

pulled the aac out and gave it a clean plus a dose of some WD-40 and so far today it seems to be driving fine

as well as that ...the other issue i had with the oil spraying out of my dipstick tube seems to be gone too.... seems odd that they could be related doesnt it ?
