This is my third set up I've done to a 88 22re
Smoother start up and engine response.I started basically cleaning the plenum
Inside and out with easy off oven cleaner and aluminum acid cleaner.Swapped out the early TPS and cam linkage to the later type Throttle bore.Eliminated the power robbing unit below the Throttle bore and clamped the 2 open water hoses to the throttle bore.I looked up 4crawlers TPS setting and used a ohmmeter to set it within operating specs.

 

Did you use the 7mgt or 5mgt throttle body?

 

So you ditched the idle control valve? (that power robbing bit on the bottom of the TB) LOL.

Not worth it for a truck that sees cold weather, but for you in HI, it's bearable.

 

The plenum/throttle bore exchange and tuned adjustments really satisfied the owner that didn't know what to do when the truck ran sluggish and a truck with even 529 gears that felt like 390 gears.

 

Stock bore throttle body with TPS swap

 

The later model 22RE upper intake has better air flow than the early model upper intake with the angled front, there is a small gain to be had by swapping over to the later style upper intake. The gains you see from this mod may not be a lot, but on a 22RE every little bit helps

 

The parts & modification was done free because we share o lot of Aloha in Hawaii.

 

doing the plenum swap as we speak :wabbit2:
