Really bad idle, heavy fuel smell

[BimmerKris]

cool thanks, there is no leaks underneith the car, and the exsess fuel smell is coming from the exhaust. im gonna try replacing the CSV cause i've been told by a couple people now that it could be stuck open, i'll check into the other stuff mentioned as well

thanks guys

Sounds like you have a spark problem.

this sounds like the same thing im going though.

so if i have leaky injectors, i would have to replace the o-rings on the injectors? how many are there?

and is there a way to test the cold start valve?

There is 6 injector o-rings in total I believe. Do you mean the ICV or the cold start injector? If you have an e, its the blue plug on the passenger side of the intake manifold. I have no clue on the I.

sorry i ment the cold start injector. how you check it?

Wow.....That is the same exact problem im having at the exact moment.
Over the weekend i changed my head gasket and now i have it all put back together.
The timing is right on!
Ive done eveything i could think of.....
The car starts just fine and runs kinda rough but while its running the smell of fuel is real strong!
When i try to rev it up it barly wants to cause its getting waaaay to much fuel. After revin it up a little there a small amount of fuel on the ground back from the exhaust :(

Dont know what to do......

Also check fuel pressure. Too much can overwhelm the injector's seal and the engine will run rich.

[skatebline]

That rich tho!?
That gas spits out the muffler? hahaha

[skatebline]

Problem fixed!
The fuel injector wiring need to be rewired and all dont now. runs like a dream :)

[bcrdukes]

Bump to an old thread but for the OP, what exactly did you rewire? How did you figure that out? Can you provide more details?

[Lyrred]

bump

Fuel line has an air leak in it. Does it clear out?
