It could be a leaking fuel injector or bad maf, oxygen sensor, or number of other things. If your check engine light is on, it may help further diagnose your issue.

    If you are interested in further diagnosing the issue, some auto parts stores will scan the checkengine codes for free for cars newer than 1996. If you can provide your vehicle info and the trouble code, I will try to narrow the causes .

My 1992 hyundai sports coupe seems to be

HI. Two issues here. The first will be with your fuel pressure regulator. this device can fail, mechanically, thus, causing an inappropriate amount of fuel to be introduced into the system. this will cause flooding, due to a ruptured diaphragm. I recommend to have this device inspected for damage.

The second issue will deal with a failed injector(s). Injectors can fail In this way, as well. This device can become filled will debris, thus, causing the mechanism to not close completely. This will cause flooding, in this case. replace any injector that is damaged in this way(stuck open).

It sounds like the carb. float is set to high and /or the needle and seat has some dirt in it allowing to much fuel inside the carb.. This will allow to much fuel into the engine.It seems the carb could use a rebuild and dont forget to replace your fuel filter.I hope this helps.

1998 Chrysler Concorde Starting Problem

First of all, you should never touch the gas when starting it, on a fuel injected engine. Whether engine is cold, or warmed up, you shouldn't touch gas pedal. That was o.k. years back when carburetors were used, but not with fuel injection. Yes you will cause flooding especially when warmed up. Now there is a good chance you have a sensor or something acting up, but I'm guessing they checked for that when checking battery problem. You may be able to check for codes by cycling key, have yoou tried that, or had codes read yet?

1987 Camaro Battery Drain

Did you try checking voltage output/charging at battery, then revving engine a bit and holding it at a higher rpm than idle to see if it is charging then? Yes if you suspect a bad connection, then repair it for sure, but try this just to see. I forget what years, but at one point in time, a lot of alternators didn't charge until rpm's were increased. You checked voltage with lights, heater, etc on at idle didn't you, then with all that off, to see if alternator keeps up with accessories & drain?

Audi 2005 A6 4.2 Flooded cabin,Navigation not!

Wow I thought they would have fixed this on the newer body style. My old 2000 A6 had the same issue. There is a drain in front of the bulkhead that gets blocked, in my case by pine needles from my tree. I used a coat hanger to clear it and then cleaned it every couple of months and no more drowning carpet. It used to be next to the battery(which they moved to the trunk) under the windshield wiper motor. I haven't checked the exact location on my 2005 but good to know it's still an issue.

1998 Pontiac Grand Am

Get a new battery. The battery seems to be too drained of power. It will still light the dash but does not have enough power to turn the starter.Of course, before buying the battery, have it tested. Probably has a dead cell.

On the air conditioner, it seems you may have the condenser drain hose pulled out of the dash hole that leads to the outside and the water that condenses goes into the car instead of to the street. Of course, it also could be that the plastic housing is cracked and the water leaks out through that.
