95 318is idle problem when starting
I have a 95 318is, 5spd and sometimes when I start the car the idle goes up then it goes down , this continues for few seconds and then idle becomes stable (in some cases the rpms go so much down that the car almost stalls). The problem occurs more often during hot weather or when the engine is warm. I have no problem with the idle once the engine runs, i.e. when I stop at the lights the idle is stable. I have checked the engine codes but nothing shows up. Any help would be greatly appreciated.
