[fidosd9]

I converted to b35 motor ljet intake 19lb injectors and motronic 1.3 got the car stared it idles fine, but i have a slight problem. when i give it gas and press the gas pedal normally the car wont bog down and rev fine to 3k to 4k with out bogging or misfiring but if kind slam on the gas pedal the car bogs down and starts to misfire, it dosent respond until I led the gas pedal go and press it normally again, then I could see black smoke coming out after it bogs down any help would be great

Black smoke means too much fuel, but i dont know that system well enough to help with a solution. You might also double check your timing.

Tps

adjustment, loose connections, or switch going bad. ( Throttle postioning switch) is my best guess.

If you're stompin' the WOT switch controls everything except the flap which you should check to make sure it's not hanging up. You're going to see some black smoke because the mixture goes rich by design. ( Only time it should happen)

I can dig around and find the electrical values if you need them.

Too rich? maybe. Black smoke can mean bad grounds too.
