So I am running tubroedit and i have code 16 on some of the time. If its on it will not run very well, jerky and stuttering. When it's off it will be smooth. Most of the time it is on, i have no idea what makes it turn off.

I have disabled the code in turboedit already, but the light on the PS9 ecu still flashes however the cel doesn't come on on the dash.

Any ideas?

I'm using a 29c256 chip, willem burner, precision 780cc injectors, stock wiring.

 

Code 16 is Fuel Injector code. Meaning that one of the fuel injectors isn't working properly, thats why when the code comes on, it's jerky, because it's probably only running on 3 cylinders or less :-\

I have attached the Factory Service Manual it should help you fix the code issue.

Hope this helps.

 

Its not running on 3 cylinders, it's only jerky at low load/high vacuum.

It will still pull just as hard as if the code was off.

 

Well the code has to be throwing for some reason. I would run through the troubleshooting just to make sure, obviously it sounds intermittent.

Hopefully someone can chime in with something better as thats all I really can say.

 

Check all your grounds etc?

 

I figured it out, it wasn't code 16 that was making it run bad, it was code 14.

I didn't have the intake air control valve plugged in,

The car is now perfectly drivable.

Thanks
