Hey guys!

My car doesn't have the idle switch at the dash anymore, or at least the wire that goes from there to the throttle. It broke years ago and i didn't really feel the need to replace it (never had any effect anyways, and I never fiddled with it).

Now the vacuum tubes, I checked but nothing seems a miss. I've been told that it might have been bad fuel, or more like diesel mixed with gasoline! There seems to be considerable knocking when you ease off the accelerator after flooring it. It also appears that the diesel is a bit 'thin', not as 'oily' as you would expect.

What I'll do is I'd use up this tankful then fill it up with diesel from another station. If by then the problem wont disappear, then... obviously something broke!

Thanks again!
