Hi, just took the zed out for run, drove great pulled realy well, had a great dive until it suddenly cut out!

i was was accelorating quite hard but had to brake quite harsh as i was coming to a bend and i felt the steering go stiff, i looked at the clocks and the car had cutt out, it fired up straight away and it was fine again.

this has happened a few times now, ive checked the ecu and its showing no codes.

could it be a boost leak?

any commemnts greatly appreciated

cheers

You might still have a series 1 ptu mate, my 93 S2 has a s1 PTU.

Mine was the same :glare:

 

Not any more :thumbup:

most likely the bov's need adjusting or the airfilters stalling the air

i take it you were in neutral/clutch in when it stalled? it's happened to me a few times, only after hard driving though. I think someone else suggested it could be BOVs requiring adjustment too. I just get in the habit of blipping the throttle when out of gear after a boot - prevents the problem from happening ;)

its as i take my foot off the accellorater pedal and onto the brake, the revs go all the way down to zero, the cut out is so smooth i dont notice if the stereos on theres no jerking as it stalls, so the clutch must be down say as im gearing down or coming to a stop at lights.

how do i adjust the bovs? and what is meant by "the air filters stalling the air" ive just put a new HPI cone filter on, and now i come to think of it, it as started happening since then.

bingo. do you still have the old one to test if it still happens with that one on?

 

The desgin of some filters can cause this, there is a way around it by shielding the filter from direct air from the bumper (assuming you don't have the stock shield in place anymore)

Bugger! I havnt got the old stock filter anymore, and also removed the stock shield as well but only because it was hanging off anyway.

The new filter is an HPI one very similar in design to the blitz SUS ones.

I'm getting the exact same symptoms now my hesitation is fixed and my 99spec front bumper is on, but i now have to replace the HKS air filter or fabricate my own shield for it as it hangs way to low into my 99spec front bumper "mouth" so it gets direct airflow into it on one side (side facing the air flow) after coming off boost.

 

But as you say, its so smooth when cutting out that if your not paying attention to the dash, you can stop and have to restart the engine lol
