Could a faulty EGR valve cause the car to "miss" or "starve" the engine of gas?

(1998 GMC Sonoma)
in San Gabriel, CA on September 29, 2010
My truck has been seemingly "missing" or "starving" for about 4 months now. It seems to drive ok then, during acceleration, it seem to "miss" and semi "jerk" the entire vehicle - as though the engine simply isn't getting enough fuel to continue the acceleration process.

Also, the CHECK ENGINE is lighting up on occasion.

I assumed it was either clogged injectors or an old fuel filter so I replaced the filter but before I spent the grand on new injectors I was told about this EGR valve thing. Since this is a MUCH cheaper fix I was intrigued as to the validity of this as a solution.

Any ideas?

You need to get a computer diagnostic. It will take you closer to the problem and don't have to guess. It might cost you about $100 but could save you a lot more on unnecessary parts and labor.

Ok quick update - called Auto Zone and they no longer do the free CHECK ENGINE LIGHT scan, apparently its a chain-wide "we no longer do" thing? But, the salesman was nice enough to tell me that AAMCO does do the scan for free so I am off to get it checked there.

2 codes came back - P0122 (Throttle Pedal Position sensor A Ckt) & P1626 (Theft Deterrent System Fuel Enable Ckt)

Any idea what these mean?

Also, when I replaced my fuel filter I added a product similar to seafoam to my gas tank - cant recall the name of it - but it claims to do just what you claim seafoam does, which is clean out the injectors and such.

Thus far, I have used about a 1/4 tank of the "treated" gas and it does seem to be a slight bit better, but the problem is still there and has always been intermittent so who knows if it is REALLY doing anything or not at this early stage.
