hi there i have some questions about my e34...firstly i have some strange issues with overheating...it happens occassionally in traffic jams...i've checked most things...new hoses, radiator service, new water pump, new clutch fan, checked electrical fan is running 1st and 2nd speed, new thermostat and fanswitch,...i dont really know what else to check...but it happens in extreme heat and traffic jam situations only so i just manage it as best i can but can't seem to solve it.Aside from that, when the temperature goes past middle...the steering starts making some sort of noise as though its rubbing against something...but as soon as temp comes down, noise disappears...i've changed all steering hoses and flushed the powersteering system and changed all the belts as well...but it still happens everytime the temp goes past middle...i don't know if anyone else has ever encountered this but it seems really strange to me.Lastly i'd like to know where i can get a used but working m20b25 MAF for e34 because mine seems to be screwed up...it guzzles up so much of fuel despite frequent CO adjustments...the setting keeps going off. Anyone got one for sale?Any info is appreciated...thanks alot.
