So a very strange problem seems to occur to me randomly but lately it has been happening more than usual. I will be driving the car along for example I will accelerate and then put the clutch in then the rpms drop (obviously) but they srop all the way down to 0! the engine dies for like one second then somes back and idles rough for a few seconds. It only happens when you rev the engine and then let the rpms drop, it never does it just sitting there ( like at a stop light) any ideas?

here are mods
Magna flow exhaust
K and N Filterchager kit + intake pipe

 

btw I have a 98 GSX

 

anyone?

 

Mine does that sometimes, but I also have teh entire FIAV removed which includes the ISC. It could be that you have an issue with the ISC.

 

are you venting or recir.?

 

Sounds like a venting BOV problem. A friend of mine has a gst and a HKS bov I think. Well thats not important. But it was adjusted wrong and letting off way too much when he shifted gears and was killing the car. We stiffened it and it got better I wouldnt say perfect.

 

I have the stock BOV right now. It is weird because it only does it randomly

 

you never did answer my question about the venting atmosphere or recirculating back into the intake.

 

recerc.

 

anyone?
