Ok, HSR is installed. Pulled the heads this winter, looked into the cylinders. Noticed somthing strange. Pistons 1 and 3 had relatively little buildup on the pistons where as the other cylinders had a lot. I am also experiencing, what I originally thought to be a tuning issue, a low rpm bounce. What I mean by bounce is that anywhere under 2000 rpm at cruise and part throttle, the car will lurch forward and backward as much as the differential gears will allow it. I notice that it is RPM related. It bounces perhaps 200 rpm forward and backward.

Is it possible that I may have plugged the wrong injectors wiring into the wrong cylinders like #3 into #1 and #1 into #3 and that would cause this problem? What would happen if I were to switch them around and try it out? Can you do serious damage by attempting this? I am of a mind to say that yes you can unless you don't beat on it.

 

Nothing bad would happen as your system is a batch fire, meaning all the injectors fire at the same time with the same amount of fuel.

as far as I remember its not a batch fire system... maybe I better ask the guys in DIY PROM...

 

If it is TPI then it is Batch Fire.

 

There goes the option of a simple fix.

 

Make sure your injectors aren't upside down though..































LOL, j/k

 

Ohm out your injectors, at least 1&3, you should see around 16 ohms or so.
