Thank You! I did the pressure check with a $40 gauge from Schucks, and they seem good for a truck with 160,000 could be better.

1 - 145
3 - 135
5 - 135
7 - 135
2 - 140
4 - 140
6 - 145
8 - 145

I'm calling it good.

Anyway then I also check timing by placing on TDC and made sure the rotor was facing #1, it was good.

I then, with the engine running, sprayed carburator cleaner on each injector. When I hit injectors 4 and 6, I got an RPM increase, infact I could essentially keep the engine running by keeping a steady supply of carb cleaner on these injectors. These banks also had the worst plugs, very sooty.

So now what do I do? Do I replace the injectors? Have them cleaned? Just change the O-rings? Thanks very much
