i've noticed lately when im at a stop and accelerate, my car jerks. it seems the pedal is pretty sensitive. and when i let go it'll jerk again. nothing too noticeable but its like the feeling of being in a manual transmission in first gear when you accelerate and let go. anyways, i thought nothing of it, thinking its because of the power behind the engine, but the other day when i pulled into my driveway (which is on a hill), i slowed down then i felt it lose power going up the hill. then i stopped a bit to move past my other car and it stalled!

has anyone else had this problem? if so, what was the fix? I don't know what it is and don't want to have to spend a pretty penny in the shop...

btw i 545 which has 58k miles on it now.

 

I had that a few months ago and I cleaned the THROTTLE HOUSING ASSY.

In HK it only cost $50us to clean it. and should clean it every 45000km
for japanese cars it about every 30000km.
your is way over.
Now it is very smooth, also change the gearbox oil

 

it looks like its getting worse. now when i start my car it sounds like its struggling at the low rpms. i popped the hood and i hear fast clicks. if i get the throttle housing cleaned how do i do it? or is this a bigger problem?

 

it quite a big job, I dont think it a DIY job, unless you know the car well
