1991 chevy s-10 bazer sucks to much gas and into the exhaust

My 1991 chevy s-10 blazer sucks to much gas through the intake and ends up causing carbon buildup in my exhaust system. And, I can really smell the gas. I have one plug that fowls. I just replaced the exhaust system and cadilatic converter. I'm getting about 2 miles per gallon less than I should be with this rig because of the problem. What could it be? Thanks, Shannon

I had a similar problem with gas smell and bad gas mileage. The problem was: a gasket that goes around the carburetor covering the jets had worn out allowing gas to pour out and burn off the hot engine. The gasket cost less than $1 to replace. When properly mounted, the gasket stopped the gas leak, which stopped the gas smell meriting an exponential improvement with my gas mileage.

Check, replcae air filter, fuel filter. Any restrictions on intake would cause poor consumption. Also exhaust restrictions, and or leaks. Once all that been taken care of, can move onto more complicated items.

95 check s-10 blazer idle is not consistent: almost stalls then idle surges. When gas is applied the engine bucks & misses severely. A friend has suggested it may be the egr valve. What are the...

An EGR that is stuck opencan very well cause the symptom you are decribing, including surging at idle and poor acceleration.

Failure of GM EGR Valves is quite rare.
A common problem on the 4.3L Vortec engines is failure of the Central Multiport Injection Assembly located between the plastic upper intake plenum and the lower intake manifold.

Sometimes failure of injector lines and/or the fuel pressure regulator (Part of the MFI Assembly) will cause fuel to spill into the upper plenum area. This can dislodge carbon deposits in the upper plenum which then get stuck in the EGR Valve and cause the symptoms that you are describing. The EGR Valve can be removed and cleaned. Replacement is not usually necessary.
Ido recommend replacement of the injector assembly however.

Gas in the oil and in the exhaust

spider type fuel delivery inside upper intake known to leak , and with repeated attempts to start , fuel gets into wherever gravity will allow , be sure to drain fuel soaked oil before attempt to start after repair and because fuel is in the exhaust , it might blow the muffler and melt the catalytic converter

Poor to no acceleration

Hi, you may have a plugged up converter. When a converter plugs up, the exhaust has no where to go but stay in the engine. This will cause the engine to get hot in a short period of time. Do a pressure test on your cooling system. If it holds pressure, this would be a good thing, if not, this means the water is going somewhere. It still could be a sign of a leaking head or intake gasket. I'm willing to bet you may have a leaking intake gasket and your water is entering the head and going out the exhaust causing your tailpipe issue and the water has loosened the carbon in the exhaust system plugging the converter. The engine will loose all kinds of power with a plugged exhaust. If that checks out, check out you MAF (Mass Air Flow) sensor. This tells the computer how much air is entering the engine in which the computer tells the injectors how much fuel to give the engine.
