black smoke coming out of exuast and backfireing as well. anyone care to help me out here?

 

You might already know this, but black smoke can be burning oil.

 

generally means you're running rich. any more details?

-i thought oil was more of a bluish color? i guess if there was a lot it could be black...

 

You're right, thanks for correcting me.

 

Yeah it's blue = oil, white = coolant, black = too much gas

 

perhaps its the map sensor. check to see if its hooked up.

 

Have you changed anything recently?

 

just dropped in a new motor and i just found out the map sensor is in bad condition. you guys think it might be the map sensor?

 

i just dropped in a new motor. and i just checked the map sensor, seems to be pretty beat up. and airborne what do you mean running to rich and how do i fix it.

 

backfires too when i rev high

 

Did you do anything with your fuel injectors when you had the motor out?

 

nope. didnt mess with the injectors at all.

 

How about the TPS? Is it plugged in? A misaligned or unplugged TPS or disconnected MAP sensor are the 2 most common things that would cause your problem. Since you put a new motor in maybe you forgot to plug in the coolant temperature sensor or the air temp sensor under the UIM? If you have a PFC with a commander you can quickly tell if the TPS or if the air or coolant sensor aren't plugged in.

 

thanx for the help imma gonna go check those problems that you suggested .

 

runnin rich!!!! burn that motha fu**in bumpa, beeeitch!
im.................not myself tonight

 

does it smoke black when its warmed up?

my car does that when its cold and backfires a tad. Running a little rich is good for the car.
Atleast its not lean, or you'll be in big trouble
