[s-cars] Surging, any ideas...?

James,

First suspect:  Old/slow oxygen sensor

Second: Loose spark plugs (just a guess based on Shawn Olsen's recent
experience)

I'd check the plugs first.  If you want to check the oxygen sensor without
first replacing it, unplug it and see if the problem goes away.  If so,
indicates slow-to-respond oxygen sensor that needs to be replaced.

Just my $0.02

> Hi, my car is acting strange, I feel a surging while driving at a constant
speed. Less noticable on acceleration, but still present, it's like
something is holding it back and then it opens up again...it's more
noticable if I keep my foot on the pedal at a specific location (try keeping
a constant speed), the car will slow down and then accelerate, almost like
the gas flow is not constant... I changed my gas filter this past summer so
I don't suspect that. It's not an agressive surging, but I feel it,
passengers can tell if I point it out.
