Hi Mopars,

I've got an 86 Turbo Z. Rebuilt engine, nearly everything else new. I still have a "ghost" causing this thing to idle rough, and is especially troubled "like 3 cylinders" upon resatrtng after its good and warmed-up. (this three-cylinder sluggishness goes away as soon as I give it some gas and get moving) (Vac lines have all been reworked and checked also) but still idles rough, with varied "unsmoothness".(is that a tech term?)

My wiring is all I can think of at this point. So, I called the dealership first and they told me this wire-bundle is no longer available. Now I know I could find one at a junk-yard, but it would probably be a lot chaper to re-wire the existing one (providing I figure out any details, like the right gauge wire and all that.)

If anyone on this site has any advice, suggestions, feedback (you had a similar problem?) . . .Anything, I really would appreciate it.
I've been plugging away at fixing up this car since April and it is "getting there" (over $4k so,far) so it is really frustrating to still be experiencing this problem. (It did it before the new/rebuild, injectors, vac lines, coil, wires plugs, inboard and outboard computers, etc. . .)

Thanks for whatever you got,
Adam

 

See if it's stored any codes in memory. Sounds like an IAC motor or MAP sensor problem to me, but there are lots of possibilities.
