Recently my accord developed this new problem... Sometimes it seems to be sluggish. For example I'll be driving in second gear (the problem occurs randomly in any gear) and all of the sudden the car would feel like it is in a high gear (sluggish, like somethings holding it back) , but once I press the gas pedal all the way the car goes back to normal... I have a 94 accord 5 speed... Just recently did a tune up, spark plugs, oil, oil filter, dist cap n rotor, spark plug wires, this did not fix... Any help is appreaciated, thanks

 

did you try turning your distributor to increase the timing? Sluggish? that sounds like a dirty air filter or fuel filter

You might want to try changing your fuel filter.

do you have any check engine codes? Is your throttle body dirty?

 

this would not be tranny related coz you said it happens in any gear randomly.
maybe a good idea to do a compression test on your engine.
clean throttle body. or maybe your catalytic is plugged up.

 

there are no check engine lights, will try to change the fuel filter... Whats weird is that when it gets sluggish if i increase throttle to 100% problem goes away...

 

Maybe your TPS?

 

small vacuum leaks goes away when you increase in rpm.
does this do it when you are idle?


clean the throttle body or maybe your battery connection is loose.

 

Maybe your ignition coil is on it's way out, just a guess. In my experience, if that's the case, it will be real sluggish and then as the rpms increase (whether it's the increase in rpms that helps, or just that some time has passed) the car will pick up again, shortly thereafter it seemingly goes back to normal.

Fuel filter wouldn't be my first guess - as you pointed out, that would be weird as WOT it runs better. If it's been a long time/many miles since it was replaced, not a bad idea regardless since it's cheap and (I'm thinking this applies to your model) easy to replace.

If the ignition timing was too retarded, he'd likely experience the opposite - at relatively low rpms, the car would run better (have more torque) at partial throttle than at full, or close to it, throttle.

I don't have much experience dealing with O2 sensors, as far as diagnosing problems, but it would make sense that an issue there might appear to go away at WOT :shrug:
