I'd bet you've got a vaccum leak somewhere. What kinda vaccum is your gauge showing at idle?

 

i havent installed any guages yet...thats my next step

 

I had the same problem with mine at first. I took it back to nelson, and what they told me what they did to correct it is to put the MAF at the original angle it would be like when it came from the factory, and of course they retuned it. It dis it so bad that it would die at idle. Now it doesn't do it nearly at all. Still needs some more fine tuning at idle. But it's a hell of a lot better now.

 

That was a small rev, as it would do it coming back to a idle, yes it would shut off time to time..Tuner said it could be a vac leak, but after testing and all it was not.. It held excellent vacuum the whole time..

 

What does the VAC should be at ? Mines is at 10 normal driving and 20 when I let off .

 

I idle at bout 15-16, but also am on a 112lsa cam.. You can see at the end of the clip( kinda long)
