After plenum pull....
I have pulled the plenum, IH's, rebuilt the TB, and pulled the cam covers. The Z started right up idles fine and drove good until you hit 3K rpm then it feels like you are hitting the rev limiter? I pulled the plenum back off thinking I didn't plug something in but it's all plugged in. Also it is throwing code #56 - Vacum sensor circuit? So what am I missing or what did I goof up?
Thanks, Daniel

Re: After plenum pull....
Your secondary system is not right either vacuum or electric...I pulled my secondaries and the chip wasn't set right and I had the same issue.
Just a thought

Re: After plenum pull....
Daniel, I would be relieved to be a dumbass in that situation! Simple fix.
See you in a couple of weeks!
