Stalling After Boost

[juddieR31]

Just installed a turbo on my 25De, runs really well, but when I pull up to the lights or even give it a good rev while sitting it stalls straight after, starts up again and runs fine tho??? Any ideas???

AFM? May need to check soldering.

Didnt do it b4 I pulled the turbo off yesterday

[paulr33]

its stalling as you are running no bov

[Trav33]

How does no BOV affect the smooth running of a car?

I know my 33 didn't come with one, the last owner must have removed it. Mine runs fine, except this last week with the really hot weather it has been not running well.

auto or manual and does it jsut stall when sitting and idling or jsut when you back off the pedal also do you have bov or not

[juddieR31]

No bov atm, and its manual, just does it after I boot it and let it return to idle, doesnt do it driving normally

[paulr33]

do a search

its covered a million times why no bov causes stalling

[juddieR31]

Thanks a lot, great help you were

^^^ LOL yeah exactly my thoughts juddier31, my fuel pump seems to be on it's way out and my car stalled a few times, perhaps it could be that ??

Someones a bit short... a million times hey?....

My manual 33 is doing the same thing this week, pull up at the lights, clutch in, and the revs drop right down, they come back up a bit but idle is a lot lower than it normally is.

my r33 does this aswell and i am running a BOV. i cant seem to figure out the problem. Anyone got any ideas?

Thanks, Mike.

try new plugs in. when i first got my 33 it was stock (except for the front pipe). when i backed off after a quick squirt it would bog down, and if i did it then put the clutch in and idled to a stop it would stall. i put new plugs in and it solved the problem.

My R33 (with BOV) has started to do the same and i have all new plugs etc. it happened after putting in the boost controller... had to take it off...

If you have installed an aftermarket bov on your r33 some afm wont like it and you will find if you accelerate an suddenly brake the car will stall 9 times outta 10 and you will find when you slow down you will have to press the clutch a few times so it doesnt stop.

I'm with MMM on this one.

There are a few reasons.

Firstly..nissans rely on a plub back BOV. The stock ECU is mapped to it...it expects that extra poofteenth of air on idle return. It's a tempremental issue dependant on things like the state of your AFM, TPS and AAC valve. Some guys can get away with it..some guys wont. Some guys will tell you that it runs ok but it really doesnt and they just love the futters.

If you insist on running VL style with no BOV then clean your AAC and AFM . If it still happens then you can "tune" it out with a SAFC or PFC.

Not really, it has been covered many times in the past

Im not going to type up another post about why as i've done so many times already.
