525i
m20
1990

the idle is really really rough...

it jumps from 1000 to 1500 rpm...

when i drive it...

u can really feel the idle jumping...

the speed of the car varies as it jumps... but when im
on the accelerator... maintaining 2000... its normal
except that i feel that there is a lack of power.

any help will be highly appreciated.

thanks!
