96 accord surging at cruise throttle
 

Hi all!
'96 Accord E-XR Vtec. 5-speed w/ 360,000 kms (approx 220,000 mi)

Car runs pretty good considering its age.Engine light has been on for
almost 8 months now but being a student and not using the car much,
haven't had it checked. Car runs fine all around.
Anyway, other day I stopped to top off my gas; car had run fine up to
that point. I drive away and a few minutes later it starts 'jerking'.
After several hundred kms of observation and a couple of bottles of
fuel injection cleaner, this is what is happening:
In any gear at between 2000-3000 rpm, the car lurches back and forth -
violently when in low gears - like it was starved for fuel then got a
sip but at a very rapid rate. Being a standard tranny, it's very
noticeable. It DOES NOT appear to be related to the rpm's but rather
the position of the accelerator. Whenever I am at a cruise - that is
not slowing or accelerating it does this - in any gear. The moment I
take my foot off the gas over accelerate- even lightly - the symptom
disappears. Even with cruise control on at highway speeds it does
this. On my way home last night, I kept the car in fourth instead of
5th as the higher rpms seemed to eliminate the problem.
Aside from the engine diagnostic, any thoughts on what might be the
cause. TPS?
Thanks!
