Easy way to lessen throttle effort??

I've just had a 325Xi ('02) loaner for a week (5sp), and was amazed at how much lighter the throttle resistence is than on my '00 328 5sp. My dad's '98 328iC 5sp has a throttle resistence similar to the loaner as well.......meaning that the gas pedal is light and has little resistance to push. In comparison, my '00 is like pushing on a brick.

This is not the "sticky throttle" problem the newer cars have been having that I describe, but I wondered if there was an easy way to lessen the throttle resistence, since I find it easier to drive smooooooth with less resistance. That, and its hell to have to adapt going from one car to the other

Thanks! Ben

me too. It is very difficult to modulate the throttle on my 99 328. Smooth starts are an effort due to the heaviness of the pedal. I would love to know if there were a lighter spring or maybe a lubricant we could use to lessen the effort needed to accelerate.

Put in a weaker throttle return spring.

"Lighter throttle return spring"...this sounds great! Where/what do I need to buy and how does one do this task? In detail, preferably, I've never done this before.

Thanks!

Ben

The 02 has Drive by wire and the 00 doesn't so that maybe something to consider.

THis should work on all cars with electronic throttle control meaning some later 323 and 328's as well as all 325 and 330's.

I believe 323/328's that were built 10/00-12/00 will have electronic throttle control or what is called "throttle by wire". It is with this new electronic throttle that these 323/328's got the new mototronics that this will work with.

For the old models meaning prior to 10/00, I've been told that you can try turning your ingnition to the on position (not started) and press the gas peddle all the way to the floor 4 times, then you will hear a beep or something and that tells you it worked


unqoute

thats wat the thread said

I know my build date was prior to 10/00, so I probably have the mechanical throttle. Anyway, will pumping it 4 times flood it?

Also, this isn't *really* what I was talking about in the first place.... I was commenting that the gas pedal is extremely stiff to push, and was wondering if the effort could be made easier.

Thanks, Ben
