well i got this 90 integra and it's been sitting for 3 years i think...i bought it from the 1st owner he said it has a fuel injection problem...but iono how to fix it...it's puffing out alot of smoke right now looks black...and alot of water liquid fulid comes out of the muffler with it...can you give me probable causes..oh yeah once it's fully warmed it feels like it's going to stall out...and it usually does if i dun't press gas.

 

bumppppp

 

the black smoke is from rich condition. also the black soot is moisture in the exhaust mixed with carbon from what is left in the exhaust. I would do a test to the fuel injection system. I would clear any check engine lights. check fuel pressure to assure pump is ok and maybe get the injectors cleaned.

 

there is no check engine lights at all

 

seafoam it

 

I would check fuel pressure and also the ignition and or dist for wear
