Default Smokes after fuel injector replace

I have a 2001 Limited 169k miles and I just replaced the fuel injectors and camshaft position sensor because I had a code P0300. After replacing them and getting everything back together correctly I started the car and it was sputtering/ not idling correctly. Basically it would act like it was running fine then within half a second it acted like it was dying lights dimmed and engine sputtered. Excessive smoke is coming out of the back and when I hit the gas pedal more smoke comes. Did I put something back together wrong or break it? Any help would be greatly appreciated.

is the new cam sensor mopar? if not, put the old one back in and see if it clears up. our cars do not like aftermarket sensors.

It wasn't mopar but this was the second one I replaced. the first one came from autozone and this one came from carpartswholesale. I replaced it the first time because a code came up saying either the crankshaft or camshaft sensor was bad so I replaced both. Then a couple months later I got the P0300 code.

Could a camshaft position sensor cause the smoke?

if it's not working properly, then it's idling erratically and i suppose a little smoke could exit the exhaust. not really sure about the smoke thing

i would also check for a vacuum leak.

I'll put the old one back one to see if that changes anything in the morning and check for vacuum leaks. Could the pcv valve cause it? I just had it replaced in November but maybe I damaged it installing the fuel injectors. Also could they have sent me the wrong fuel injectors and they are delivering too much fuel? If so would that show up on a fuel pressure test?

It's good to check for vacuum checks-

Other than that, two things were changed, no matter how foul a bad cam sensor isn't going to make it smoke.

Incorrect injectors will!

^ x2 on that.

what color is the smoke?
how does the smoke smell?
do the new injectors look identical as far as color, size, shape, number of holes in the nozzle?

they make low impedance and high impedance injectors, it's possible you have the wrong ones. wrong flow rate is also possible. usually(but not always) they are color coded.

The smoke color was blackish and it smelled like gas. As far as the injector identical in size, color was different I think the old ones were blueish while the new ones were grey, I didn't look at the number.

I managed to fix the problem. A guy at autozone said he had the same thing and what happened for him was that he didn't lubricate the o-rings first on the injector (I didn't either) and that pinched the o-rings and caused gas to leak. Sure enough when I pulled them back out three of them had pinched o-rings. I replaced them and now that problem is fixed.

Still have the code P0300 though I have a different thread started for that. Any help would be appreciated..

P0300 effecting all cylinders

Thank you everyone for your help with the fuel Injectors.
