So today I changed the intake manifold gaskets and fuel injectors on my 2004 Chrysler Pacifica because of a misfire in 5. Switched everything out cleared P0305 code took car for a test drive and everything was fine. Got in the car the next day and car felt like it was misfiring bad and white smoke was heavy from the exhaust and car almost shut off. Got home safely, check engine light wasn't on, so I revved the engine at 2000 rpm and then the check engine light came on with a P0172. I have rechecked all connects and car is still stalling and white/gray smoke is coming from exhaust when I rev the engine.

Any suggestions?

 

likely did not put something back on right a gasket is rolled or something not plugged back in 172 is usually a vac leak

 

I didn't want to have to drain the coolant again, but that's the only thing I haven't done since replacing the two gaskets. But the exhaust smells like gas. The air filter wasnt seated right and I reseated it, but the problem still existed.

 

it will be on the intake it self. and why are you having to drain the coolant? did you replace the lower set of intake gaskets as well? why was that done ?

 

Yes i changed the lower set because they where cracked after 16 years on the car.

 

Thanks for the help, found the issue, all 6 new injectors were bad⅖
