it could be either one of your orings got torn when you installed it (use lube LOL) or its just unburned fuel in your exhaust, (assuming your last injector got stuck open) that is just getting burned off.

If the car seems to be running fine, id just take it on a nice 20 min drive to get all that crap out of your exhaust. beleive me it takes awhile, i had the same thing happen to myself and i thought i seriously fVcked something up.

If it's black smoke, that means you're running very rich; one or more of your new injectors may be bad.

No its just white smoke. But i took it for a 2 mile drive today(just around my house) and it doesnt smoke that bad. Tonight i will take it to town to put some gas in it. I will post back to tell y'all wat happens! Oh, and also it kinda bogged out or spuddered when i was in first and was revin up? Anybody know what could be causeing that? Maybe she just has some bad gas ...well anyways thanks for your help
