Idle + Boomba problem
Hi guys, i hope you can help me...
i just swap some parts...
i had 70mm fullblown tb, JMFAB Intake Manifold, now 75mm Boomba TB and AMS F1 Manifold
now i have some idle problems... cold is perfect... 1200-1500 rpms and good AFRS, but when the evo is warm the the rpms bounce between 1000 and 2000 rpms and the engine die...
i just checked with evoscan and the problem start at 80C degrees
i don't know if i need to adjust the speed density tables...
after boomba tb and ams manifold the idle was perfect.. 1000-1200 with no problems...
i hope you can help me...

Also, check for boost leaks when car is warm. It may be totally leak free when cold and as it heats up a leak is created. Did your torque the mani to specs? New gaskets?

boost leak free, new gasket, everything is fine....
i just adjust the ISCV Initial step position with ac off table and now the idle is fine..
now the problem is when i rev the engine the rpms go up and then fall to 300-400rpms and the engine die...
do you think is a boost leak??

I know I am not the original poster, but I am about to purchase pte1200's since my cam is helping max out factory injectors at just 15lbs. Hopefully no news is good news, but I am going to send my info to Tom at TScomp to get my car up to speed when I get going with parts.
