This makes me think that there is a loose, or shorted to ground, wire in there somewhere. You just joggled it a bit, now it may have jumped back. Check the head temp sensor wire where it enters the crimp at the sensor. The insulations hardens and breaks there and can easily short to ground. You will have to slide the outside teflon sleeve back to see this. > When it started running really badly, I noticed that the gas pedal wasn't > giving the desired results.

Suspect #2? It occasionally happens that your fuel system can provide enough gas to hold the pressure up when at idle, but not at speed. The culprit is often a clogged filter, but a clogged screen in the fuel tank exit is also possible. The test is to figure a way to watch the fuel pressure while you're driving and having the problem. > <Jim>If this is a new engine, </Jim> > > Nyet.

Are you also using the 73 brain and temp switch? You should be. > idle for a few minutes and took more time for problem diagnosis.

Doesn't match the > problem, but that's what I saw. I see no common FI problem here. The only thing that 2&4 have in common are the cam lobes, and I really doubt that you have a cam problem. A compression check might relieve any doubts. > I'll check the wires to make sure I don't > have a set of injector plugs crossed. Also, I thought the injector points > might not be working properly. This is not a FI trigger points problem.
