Hello again fellow addicts, at least that's what my wife calls me, anyway, I have finally got around to doing the compression test that I had been fearing would bring the results it did. 120 on 1,3,4 and 0 on 2.

Question is, am I totally screwed? I don't have access to an air compressor to do the other test where air is hooked up to the cylinder... What do I do next? Valve cover off? What are jet valves? I read about them but I never had a car that had them or if it did I did not know about it.

I'm hanging on to the hope of not having to do a rebuild. I simply can't afford that right now, is it safe to keep driving on three cylinders? It does great at highway speeds, is just at idle that she seems to have an issue, I can't get her dialed in because she shakes at idle and I don't want to crank up the idle speed.

Any advice? What do I look for when valve cover is removed? Worse case scenario? And not so worse case? Are we talking valve job?

I really like my truck, I just don't have lots of money to use, (these days who does right?).

Anyway, thanks in advance, all and any advice will be appreciated.
