My gas guage sometimes fluctuates? Could it be the fuel sending unit?

Get into the trunk and clean the contacts on the fuel sending unit, if you're lucky it might solve the problem. More likely, the sending unit will need to be replaced, but it's an easy DIY to remove and replace. Just need an adjustable wrench to loosen the sender.

had the same problem, sometimes it worked, sometimes just whacky, replaced sending unit problem solved 86 190e 2.3, not a hard job

thanks guys!

I'll try to clean it first. What do I clean it with?
