I dont know what it is but im just going to explain it as best
as i can.

When ever i rev my car, so when my foot pushes the pedal
down it lags in revs..

the response is all wrong..
it has never been like this before...
just occured..

had my clutch changed 1 month ago..
if that could contribute to the factor..

Does it bog certain rpm?
when you step on full throttle car goes normal?

OMG.JAI xD

check for plug conditions.
water contamination in the plugs.
or coils.
or it could possibly be that one of your coils are lacking in spark.

ask the place where you got your clutch done if they washed the engine bay after the job.

thats right, it could be lacking spark, same happened to my old charade, it kicked in after 3000 rpm or something needed new plugs, leads and dizzy and it went fine

yeh car goes normal when i go full throttle..
just at the really low rpms..

so if its idling.. and i tap it.. theres a lag

i will try changing the spark plugs..
they seem like the problem..

So you're saying at like 1500-2000rpm when you just go full throttle it bogs?

Its because you need to ease the throttle up the revs.

sounds similar to mind, it could be the 02 sensor playing up

Try unplugging your 02 sensor, engine check light will go on, drive around to check if the bogging is still there. If the bogging is still there then the problem is else where, if bogging gone, need a new 02 sensor

The engine light will go on, don't worry to much abt the light, your just testing

wow i think ur spot on..
cos i when i got my clutch changed the o2 sensor was stuffed up..
the engine light was on.. then i got it replaced then it went away..
so maybe its still the o2 sensor..

check for a vacuum leak from any vacuum hoses coming out of your intake manifold. at idle and low revs, your IM is producing max vacuum, at full throttle, your IM is producing zero vacuum. if there is a hole in one of the hoses and its drawing in air, could cause it to bog a bit. only other thing i could think of is your ignition timing might be off below 3000rpm, in which case, reset your ecu, or advance the timing and see how it goes.

Also take off the dizzy cap to check if there is corrosion. Clean with a brass wire brush.
