Rb20det cutting out low revs

[Semih_Ozdemir]

Hey guys. Ive posted before about this before. I thought i fixed my issue where i found a slit hose. my car would cut out at low revs, complete power loss then come back. Its completely stock rb20det

Ive done all my research. Ive read many forums but nothing is helping me.

I start my car go down the drive way drive off and bam at like 1-2k rpm the car starts hesitating and i cant accelerate. Its happened after ive put a dump pipe on. All connections are fine. Everyone keeps saying different things im really confused. Can anyone lead me into the right path. What should i be looking for.

It doesnt sound like a vacuum leak or coilpacks because its not missing.

Check afm and cas plugged in (all the way) battery ok and terminals tight?

I checked airflow meter. It seems to be working fine. Ill have a look at the cas and battery.

When the car sits and idles it seems fine. Then once it gets abit warm itll shut off

This is a never ending issue with rb20's... the last time this happened to me i ended up replacing the tps and it fixed it. Cleaning the aac valve might help too...

[Semih_Ozdemir]

Tell me about it mate. Could be anything really. I had a look at most stuff. If there were leaks or not. All seems to be fine.

Car was perfect untill i installed the dump pipe... maybe it needs a tune?

From my experience a dump pipe wont cause that, unless the o2 sensor is stuffed... have a read of this thread

UPDATE;
I took it for a spin today. It was driving fine. No cut outs or anything. Was boosting harder than ever. I dont wanna keep driving and the next day it plays up on me. i doubt the problem fixed it self lmao

This is happening to me i have absolutely no idea why. It seems to drive fine nothing wrong then all of a sudden it cuts out its like the key has been turned off while im trying to accelerate. if im at a complete stop and it begins to do it, it sounds cammed and wil rev high then drop down to the point of almost stalling then rev back up then do the same thing. When its doing this i cant give it any accelerator at all it just bogs down, ive replaced the CAS twice, checked TPS, AFM Cleaned, checked coilpacks. I have no idea what this could be :(
