Car: mkiii
Mods: Lexus,550's, ct 26 with 57 wheel, Aeromotive set at 40 p.s.i. timming 10ish degrees
Problem: car's idle is low (after it's warmed up) and the car stalls when I let off the gas, but not every time. Also, I can hear it popping and back firing when I let off the gas. Idle's fine when cold.
I think the problem is: timings is to retarded, to lean, vaccum leak, bad v.s.v? or all four.
To solve the problem: besides retimming, if it's to lean how do I fix that?? raise the fuel pressure? And of course check vaccum leak. Anything else that you guys/ gals can think of?
"Thanks ahead of time"
