if I'm very light on the throttle, car goes smooth up to 4000k, if I get a bit heavy it stumbles BAD. :(

any suggestions? considering all the work I did, I don't know where to start

stumbling could be VERY rich or VERY lean. don't drive it ! load mitch's map then you can drive it!

Stumbling.. what do you mean exactly? https://www.nopistons.com/forums/pub...1047683561.gif

cuts out, like no gas. or no spark type of ****, or baybe too much gas.

hmmm

I'm assuming you replaced plugs and wires.

Oh ok.. mine does this thing were it feels like the car wants me to go faster.. no joke. It's like some type of pushy feeling..

Get your hands on a wideband, quick like!! https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

Could be those injector wires you possibly mixed up. Get on a wideband, don't blow it up yet https://www.nopistons.com/forums/pub..._DIR#>/sad.png
