Check fuel pressure. I'm betting it will fall like a rock once the vehicle is shut off. Typically the fuel pressure regulator is the problem. It is located on the back side of the CPI unit. The upper plenum will need to be removed in order to replace the regulator. This is a very common problem.

I have 95 Dodge Dukota runs good but misses and smelles like gas when driving and gas fumes bad when truck is turned off


Possible fuel leak caused by Ethanol added to the fuel rotting the seals or just a damaged fuel line. Get it fixed before it catches fire.

What causes gas smell from 2006 Saturn Ion--no gas puddles, or loss of gas mileage. Seems to happen after car is turned off and fuel level in gas tank does not seem to be a factor.


This is often caused by corrosion on top of the gas tank. Mud, dirt and water get thrown on top of it and causes the metal to perforate. You can smell it on the move because the fumes dissipate at the rear of the vehicle.

94 4.3 vortec getting horrible gas mileage why???


Go to You Tube Video to find the problems
with that motor & the solution
A local repair shop can check bulletins in their
data base for the fix also
Most likely intake gasket,if you use Dex Cool
It eats gaskets & the vehicle is old ,so you can expect
to be constantly working on it

My car is starting but not right away,i have to hold the gas down sometimes! what could be the problem?


It could be that fuel is not be delivered fast enough. Try changing the fuel filter first.

Have you noticed a drop in your gas mileage and are you smelling gas fumes? You may have a leak in the fuel line and that will ****** the fuel delivery.

If these items don't help, then you might try changing the IAC (idle air control) module mounted onto the front of the throttle body. It's about a $50 item.

1987 Isuzu pick up 2.3 . Carburetor runs much to rich. My gas mileage has gone from 27 mpg to 17 mpg. You are also able to smell the fumes due to the carb. not running properly.


It's either a stuck float or the choke is staying closed. If you're smelling gas, then it's probably the float. You need to rebuild the carb.

Buick regal 92 3.8L Horrible fuel mileage


Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.

Idle low then hi, and gas smell, and bad gas mileage


This should show up easily on the ECU diagnostics computer at a mercedes dealership. Basically your fuel mixture is way too rich causing your car to be heavy on gas, have a raw gasoline smell, and not run right. Something like this can be caused by a defective oxygen sensor (but that usually produces a check engine light) or it might even be a defective ECU. There is really not way of knowing for sure until you do a proper diagnostics where they hook up your exhaust at the same time and do an emmission test. In most cases it's some sensor that needs replacing.
