Well everytime I start the car and try to move it, it just boggs. It does this for some time till it gets alittle hot and then it runs fine. It is a stock dual cam KA with 105k miles on it.

Here is the vid so you know exaclty what I mean.

When I accelerate just a tiny tiny bit the revs just fall to like 500. When I release the gas is when it jumps back up to idle.

Has anyone had this problem or know what it could be?

Thanks in advanced guys!

Muffler bearings are worn out. I'm sure someone on Zilvia has the hook up on a pair. GL

muffler bearings! lol coming from the guy with 9 posts and a red square.

looks like your idle control is fine, cause it keeps jumping back up to idle... I really don't know what it is, short of a weird vacuum leak... did you just pick up the car, or has it steadily gotten worse?

It sounded like you are miss firing, I slightly have the same problem. When I just start the car up and drive off it bogs a bit dropping about 500-700 rpms from where im at (like if im at 2500rpm it drops to about 2k). This only happens for about 2 minutes until the car warms up, weird thing is that if i push the clutch in and accelerate the rpm climb up like nothings wrong.

It used to bog alot but I used seafoam and it made it better.

But yea It might be your Muffler bearings, lol

Do a tune up and see what happens.

Do a tune up, do a compression test and see if your car jumped timing. It almost sounds like some metal on metal contact. Take off the valve cover and check the chain guide.
