in my last post........

"last month i noticed by the small amount of black smoke coming out of my exhaust that my car was running a little rich......

well, yesterday i cranked my car and it idled for about 4 minutes then huge amounts of black smoke started coming out and the car began to spit and sputter and went dead....it smelled like someone poured gasoline all around me it was so flooded out.

it would not crank after that..... unless i held it to the floor and it would crank for a second , spit and sputter with black smoke, then go dead.......

does anyone have a clue what this could be? or has had the same problem? any help would be greatly appreciated. thanks! "


........well i replaced the MAP sensor and fuel pressure regulator and it is doing the exact same thing....barely running



exept now while it's barely running and spitting and sputtering it looks like the oil pressure has dropped way down...... and when it's idling its in the red and at mid-rev its at 1/4 up the guage... it has never ran this low.... and when i check the oil, it is about half an inch OVER full on the stick...
this blows my mind..... the car is always a little low on oil because it has a small leak.... how could the oil show up so high on the stick if i know i put the right amount in it when i changed it 2000 miles ago , and with a slow leak it would be less than full.......

could this be related to the low oil pressure?

 

The addition to your oil could be water or gas. In your case, it might be gas, based on your symptoms. Drain the oil and check it. If it is running that rich and diluting the oil, it's going to ruin your engine internals. You might have an injector hanging open or a f/p regulator leak that is being sucked in the vacuum line to the regulator.

 

one thing, if it is a inj., it could be mechanical, i.e., inj. internal fault, or, it might also have one or more inj. control wires shorted to ground, holding one or several at 100%DC

 

shoebox your a genious

fuel in the oil... that has to be what it is , because it is so high on the stick and come to think of it, the oil looked very thin and deluted.... this explains the sudden low oil pressure

if fuel is being sucked in the vaccum line how would i correct this? i just put a new fuel pressure regulator on it.......

and if it is an injector, then how will i know which one is sticking

 

Pull the vacuum hose for the regulator off at the manifold end and check it for gas. Replace regulator if contaminated.

Injectors can be checked by unbolting the fuel rail and pulling it and the injectors up, out of the manifold. Let them sit above the manifold while you pressurize the system and see if there are any that drip. It wouldn't hurt if you had a fuel pressure test gauge, too.

 

the problem has been pinpointed.....

i pulled the injectors out, hit the key, and tadaa , one is stuck wide open, and another comes out a little bit, and the rest, none

stuck injectors causing fuel to get in oil causing low oil pressure and engine to flood.... another job well done by shoebox

thanks everybody

 

well i replaced my injectors and changed my oil twice and now my car will actually run and fuel is not running into my oil anymore......

however, it runs like a$$. It smokes bad every now and then. sometimes black, sometimes white. Sometimes it misses and tries to flood out, then smoothes off. It runs worst when i cut it off and try to crank it right back up....

i figured it might be fouled out spark plugs (due to all the flooding problems i had before) so i replaced the plug on the cylinder closest to the driver (#1 i think) because this cylinder that had the stuck injector....

the plug was jet black and was wet with fuel so i figured this was my problem. but when i replaced it it made no difference at all.....

ANY suggestions will help.

also, if i accidentally hooked the fuel lines up backwards would it cause the car to run like that?

 

The fuel pipes are two different sizes, so it would be hard to install them backwards. I would bet your O2 sensors are badly fouled as well. Some new ones might be in order.

 

I saw that you said it has white smoke......coolant burning. That could be a leaking head gasket. That can cause your spark plugs to be fouled as well as your O2s. Not too sure how often, or much, this white smoke happens but it is something to look into.......

 

I have also noticed a few oil changes that my temp is little above 40 on the highway as it use to be 60 on the highway..At idle..it sits at 20 which is the norm. Should I be concern that the oil temp is not idling at 60 no more on the highway.

 

ouch... that is not something i wanted to hear... i'll look into this. hopefully its not a leaking head gasket.

 

Are you sure you mean oil temp?...... Sounds more like you are talking about oil pressure?????

Probably not a good idea to hijack someone else's thread.

 

well i checked my water and it is full so its not a leaky head gasket. The car runs a little better but there is still lots of black smoke and sudden hesitations.

The car is flooding out bad. I don't know what else i could do. I replaced the MAP sensor, Fuel Press. Regulator, and injectors and still runnin WAAY too rich

any suggestions?

could it be the computer? fuel filter? fuel pump?

p.s. thanks injuneer

 

What about the O2s that have been mentioned more than once?

 

check fuel pressure also
