right side of throtle body , just under the throttle position sensor.
it may only need to be taken out and cleaned?

i had a shop look at it,
code 23 was the only code they printed, and they said my o2 sensor was open
and the IAT sensor was low.
I've changed the oxygen sensor now, and after i changed it the car ran fine for about 2 days, t hen spilled gas out of the throttle-body this time, last time it was that vapor canister or whatever it is that's next to the air cleaner on the 92's. |

Your a v6 right? If you have the stock aircleaner, its down in the canister that the filter sits in.
Mine, the plug became bad and was letting the wires come out. Might check that before you replace the sensor. |

Luckily i've got a V6, nothing but space.. but this whole starting to drive and seem road worthy just to have the same problem's getting very old quick. this is the 3rd time it's leaked gas out.
first 2 time's, vapor canister, and this time i could smell gas pretty bad, so i looked to see if it was leaking out from there again. and i looked at the air intake hose and at the top where it connects to the throttle body it was all wet, took the hose off, and there was gas in the tube. and just dripping out of the butterfly. |

how does gas come out the TB. there is no gas in the intake system, TB only regulates air, i like these strange problems,
how about if the fuel pressure regulator fails and u have a paritial stuck open injector on a cyl. that has both valves closed, then the gas might back up into and out of the TB.(ignition on car not running)???
anyone else have an idea on this?
question, did u do anything that might have swapped the fuel lines, maybe the return is hooked up to the pump.. just brainstorming. |

The charcoal canister has a vent line that goes back to the tank. If the canister gets messed up or the wrong vacuum line gets hooked to a full vacuum source ( ask me how I know...) then the motor can suck fuel through that vent, the canister, purge, and into the TB/plenum. _________________

That is exactly what happened to my kids car. look back by your fuel tank, there are 3 lines and a vent. if you look very carefully minus the vent line (obvious) the three remaining lines are different sizes, make sure the rubber lines have not been crossed, which leaves only 2 lines. the third line is high pressure fuel and has fittings and cant be confused. Just make sure the two lines that are spliced with rubber are matched to the same size hard line. hope that made sense.
be careful when swapping lines around back there, there might be fuel under pressure. watch your eyes and sources of spark/heat. _________________ 88 Camaro IrocZ Convertible 5.0 TPI...

Dude, trying not to be rude here, but every month you come in here complaining that your charcoal can is blowing gas either onto the ground, or into the intake, and every time we inevitably tell you that you need to check the lines at the tank.
You need to check the lines at the tank! |

I checked the lines, before, that's why i keep asking, that's why i had a shop look at it, maybe i am missing something. I'll take a picture of the hack job that was done in the back.
Don't mean to irritate or earn the rep some of the other younger members have earned themselves, i'm just saying they cut the original metal lines and they cut a whole in the top shelf behind the seat to try to pull the fuel pump out that way, everything is mickey moused.
further more, this thread wasn't just complaining about it and repeating. it's wanting to know what exactly the shop was telling me.
I'm no expert, and am learning as i'm going, that's why i get on here, and ask you guy's since all of you have been doing this way longer than i have. |

Like I said, I'm really not trying to be a dick. I totally understand having to put stuff back together after a previous owner got ahold of it.
IMHO shops are not the answer here. Those guys get paid to do menial crap, they can't figure out where fuel lines are supposed to go.
If it were it my car I would seriously consider just replacing all four hardlines. |

The more and more I look into it that's what's going to have to be done.
but doing it that way, i won't be able to use that hole up top they cut out. and if i remember right what i've read on here before is you have to drop the rear axle, and it's a pretty big mess isn't it? |

More of a mess than dumping gas into the throttle body?  |

Don't change any sensors till you fix this problem. Running way rich will send the O2's into a s***-conniption.
Fix the lines first, then clear codes and drive the car. If any codes are then thrown, replace the sensors.
And don't pay a shop to throw a code machine on it. Just do it with a paper clip like the cool kids.  |

| I guess some people's opinion of PITA is different than others. I swapped the fuel pump on my 87 in a bout 4 hours. It took about one hour to get the car cribbed up enough to lower the axle with a floor jack. Not that big of a deal, atleast you know this going in. You have probably spent more time searching online for the quick fix? |
