Remove the T-15 screw and 7-mm nuts from the cable shield.

I labeled everything in this project w/ blue painter's tape for 2 reasons: 1- to make sure every screw goes back into the spot it came from, and 2-it helped me remember everything I was doing, plus if you see any blue tape left at the end you know you missed something. So, next remove the cables from the pulleys. If you reach under then and pull up, it will give you slack you need get them free.


Pull the plastic retainer from the bracket.

Next in the supplement manual it says to remove the fresh air hose from left and right side of the throttle body extension. Problem is (at least on my '90) there's no room to remove the hose from the cable side. So, that comes later.

Remove TPS, IAC, and MAT connectors. Remove the coolant hose from the plenum (I removed it on the passenger side),

Why thank you, Cliff. Solutions helped me a lot w/ that. After I finish reading my automotive training manual, maybe I'll have the courage to try a 500hp rebuild. I'm a little ways from that yet though. But the info is there.

Joe,

Not sure I am quite as meticulous as u are in documentation. Guess I have done it enough times, the picture is in my head at this point. Good job.

With the plenum removed, and especially the coil packs, th grounds are not that hard to access. I should have done the rag trick to the drainhole. I only drilled mine out to 3/8" and flushed it with acetone.
