i put on a new skunk2 intake manifold and throttle body and like im burning through gas like no tommorrow i have no vacuum leaks only thing i did different was i didnt use those rubber bushings things on the fuel rail because it didnt let the rail sit low enough. i have no fuel leaks no leaks at all. and i ahd to wire in one obd2 fuel injector because the other one had a crack in the plastic housing..... i dont get it i went through 3/4 a tank and drove about 50 miles it smells like gas horribly when im drivin

 

if i sit in one spot it gets the street behind me wet in fuel and there just a buttload of fumes comin up

if the street is getting wet with fuel, there is a leak.
find where its coming from.

 

the fuel is coming out of the exhaust pipe. like the fumes haves traces of unburned fuel.

 

if it was fine prior to installation, something is obviously hooked up wrong, changing itm and tb would not do this. idk where to start, maybe someone else can help. my brain is fried for the week. if its pour fuel out the exhaust, i don't see how its even running normal enough to drive, thus you shouldn't be driving it around.

 

You did a hurry-up job, now one or more of the fuel injectors is stuck open. You need to install the correct fuel injectors and O-rings and wire them correctly. When done there, you also need to change the engine oil.

y change the oil? and i didnt know what to do with the little rubber spacers because with them the injectors werent even seated in the lil holes in the manifold.

 

If the injector is stuck open the fuel probably made it's way into the oil since there's no way the motor could burn it all.

 

I agree. And the gas-diluted engine oil will not properly lubricate the engine and will reduce cylinder compression.

 

ok will do i will be tearing it apart after i find an injector and do some research on what to do bout the spacers thanks for the info i was stumped .

 

maybe somethin is wrong with the injectors? was the swap ever boosted cuz i boosted my ls and had to have my ecu chipped for fuel management. but if your ecu is unchipped then i have no idea.
Good luck

 

it wouldn't be dumping ridiculous amounts of fuel at idle, and at the wrong time b/c its tuned for boost.
whats been suggested should solve the problem.

 

Excess fuel will wash out the cylinders and the remove oil from the rings, this can cause some damage to the block. 3/4 of a tank in gas for 50 miles is some serious fuel dumping.

I'm amazed it didn't foul out and run on 3 cyl's.
