Need Help With My Bimmer Please ;-)

Hi everyone...just bought a 1998 BMW 318 IS and would like some advice with some issues it has....1st It has developed an intermittant misfire...probs needs new plugs but didnt know if they suffer from this....2nd the Blower Motor is also intermittant...isit likely to be the motor or controls?? ....lastly the fuel gauge has stopped working??? Any help/advice would help and be greatly appreciated...thanks matt

Hi Matt

The is is a cracking car! Give the old gal a service first,then report back on the miss fire!

Did the fuel gauge work then stop? Or never work?

Welcome :)

Welcome to BMWOC :)

Misfire could be plugs or a dodgy coil pack,the heater is more than likely the 'hedgehog' resistor,and fuel gauge is probably a fuse blown ????

Snyper pretty much wait what i was gonna say lol.

Snypa and Ian covered it mate

Get the is in for a service and see if it changes anything

Thanks guys :-)

A blown fuse wouldn't cause it.

Where is the misfire? Is it noticeable on idle or higher revs?

As it is a four-potter it would be hard to eliminate a coil-pack by just pulling off but bang a high-voltage meter across "Earth" and its "Low tension" feed and notice any shortfall...

... Other items to inspect are:

MAF

TPS

CPS

... And any air-leaks via intake hoses.

Good luck ;)

Hi again guys...the only problem left is the blower controls...ive had a look at the wiring and it looks okay...whats the deal with this hedgehog resistor? How do i find and test this resistor? Thanks matt

Looks like Dabs covered everything else :)

Hedgehog resistor is in the passenger footwell on the right hand side,they are a common failure...............have a look n YouTube for a vid to find it,its an easy change :)
