Bmw 318

My BMW 318 i SE misfire and the garage has published an engine diagnosis. No fault has been raised. He said that the fuel filter could be blocked or the leads should be replaced. Anyone know where the fuel filter is it?

If it's an e30 over the deck, if its an e36 in the car under the passenger seat is to question your theanswer.

try the fuel tank

Plug-and-duct plugs should be changed each year, or you pay for poor performance and fuel economy. I expect it to be just a problem of the HT circuit, thus changing the rotor arm and distributor cap too. Do not miss the firing order on the new ceiling! Find out who is the "front" of the CAP, he scored with a little nail polish, and the work of the new situation on her in the same relative position as that of your engine, you can remove the cap and replace with the new. stickers on the end of the plug causes a good idea too.

The fuel filter may Coke, as in appearance, tight in the car near the rear axle ... The fuel line feeding the pump, which is quite similar, but the cables running to the power and ground, and pump in the filter. A compatible filter should cost no more than ten pounds. Doing a good job and replace all the fuel-pipe clips, you can see, if corrosion on them. In addition, if the fuel-pipes Search perished, they may have pinholes in those who are almost impossible to see, but can not stop your car dead ... Five pounds worth of new fuel line will work well for you the next ten years!
Clearly, work on the fuel system, you should disconnect the negative battery cable, and use a line-clamp to stop a fuel spill on you.

It was under the car just before the fuel tank
