Whats up guys! Im having idle issues on my brand new build. I have a new built 2.4 with build head and s3's. My problem im having is it dies everytime i push the clutch in over 2k rpms. me n my tuner friend tried everything. The tps is at 16%-99.7% and the iscv seems to be working. Played with all the iscv tables nothing helped. Added timing at idle, still dies, bumped my base pressure to 48, etc it will not catch itself. Anyone have s3's that can help me out?? Btw i have quartermaster twin. Thanks guys its been killing me

 

Who did the build and tune in Utah?

 

Hunter machine assembled my shortblock and i did all the tearing out n building. And it isnt fully tuned yet because i cant even boost im on break in, but my buddy jose usually tunes it

 

At idle and you clutch in, does it die? Or only over a certain rpm?

 

Not at idle just when i push clutch in over 2k rpms while going to a stop

 

Are you on a speed density? Or MAF?

If your on MAF does you BOV vent to atmosphere?

 

Speed density

 

Post a picture of your ISCV on demand ac off neutral table.

 

Ok i will after work

 

Here is the iscv demand ac off neutral. I cant figure out how to load pic from my phone but numbers from top to bottom are

155
143

You have a pm.....

 

Has this been solved yet? I'm starting to think you may have a leak somewhere.

 

No i drove it yesterday and doesnt die if i go to stop and wait to push clutch in under 2k rpms. But i sent my map to a tuner so he is gonna look it over

 

I start to have the same problems but not all the time. At cruising at any speed and i put it in neutral, then the car sometime stall out.
But my main problems is in cold start and after a hard run. Cold start, i have to keep my foot on the gas or else the car idle up and down so low that the car stall out on idle.
But after a hard run, then at a stop it will go up and down between 2000-1400rpm for 15-20seconf then the idle will stay at 1800rpm.
Well let me know how u fix yours so i can fix mine to.

I have the same built like urs. 2.4L block 9:0 manley piston and tt ibeam manley rod, gsc s3 with bc valve spring retainer and also quartermaster twin 6legs clutch.

 

I wonder if the a boost leak anywhere would cause this probblems???!?!??!!
