Hey everyone, i'm new to the forum and just picked up an 87rx7 turbo 2 about 3 months ago. Got a bunch done to it so far. But recently its been ideling very poorly. It bounces below 500 then back up to 1000 and up and down like the tach needle is bouncing and the car is struggling to stay on. My vacuum is only reading as high as -6.8psi then it drops down and bounces between -3.4psi and -1.3psi on my greddy and then engine eventually stalls out. I check all of my vacuum lines but to no success. Anyone have any ideas?? also wuts the highest boost i could get out of my setup? i was hoping 16psi thanks!

 

Well, for one thing, we don't know what the bunch of stuff done is so we don't know how much psi you can make. What exactly is done to the car, what is your setup?

Two, does your idle problem go away after it warms up?
