ok so here it is i have a 94 vert i just recently did a 5speed swap and while i had the engine out i got rid of the erg b/s and well every vacuum line on the car except the fpr line and the brake booster and at first it had a slight miss at idle then after messing with it i got it to stop or so i thought lol now it has clouds of black smoke and in the morning when i start it it stumbles then dies unless i race the engine then it idles ok but runs and at certin speeds most noticable in school zones it has a speedy miss and hesitates when i get on it for a split second

it has a new o2, both coolent sensors, maf, tps, iacv, plugs, wires

im at a loss any help would be great lol

maybe unrelated maybe not i just noticed when i turn my heat on the idle drops a little and some times makes the idle drop to like 500 thanx any one

I know this is NO help, really, but it's a KA. I have NEVER, EVER seen a KA NOT run rich.

Mmmm, was the car running like the prior to the swap? Did you buy the car off someone that "did engine work"?

You need to add some grammar and punctuation. I can't understand a thing you said.
