TB/Plenum Swap Done

Wonderwyrm · 11-22-2006, 10:47 AM

So I did the swap this morning, is there anything else I need to do to the car? Reset the computer etc etc?

I get a slight whine type noise at around 1.1k-1.2k rpms real fast and then it goes away just as fast, is that normal?

I would reset the computer, then let it idle without turning anything on or touching the gas pedal for 10 minutes. A faint whistle is normal, anything else and I would check for vacuum leaks, but it would run rough if you had a leak

what TB and plenum did you use? If nothing else I'd run down to any local dyno shop and do a quick run to verify you are running a safe A/F ratio. Intake mods always throw it off a bit and sometimes it can be enough to be bad... not all the time but often enough to check it out. Besides... then you'll know exactly what your power output is and where it makes power.
