Question about Cars & Trucks
1997 astro Ticks over fine but when running with areal time reader connected showed intermittant missing on all 6cylinders. This is after changing module due to engine fail to start, due to very low output from HT. Changed ignition module. Repaced module had the same simptoms as now, tick over ok but missing on load.Seed to run ok for about 1 mile
The coil shud be testd-causes many ignition issues--also computer cud hav problems with fuel injector drivers

Check fuel pressure. And check for vacuum or air leaks- vacuum hoses, intake manifold gasket, the big air boot to throttle body assembly. Any trouble codes?
How is output from HT now? Do you have a blue snapping spark at the spark plug wires now? If spark is weak, it might be a crank position sensor- it can be tested to some extent, and should have a reference voltage to it, about 5 volts.

check for vacume leaks on intake and other vacume hoses. random misfire is also usually a clogged fuel filter or pressure regulator. could also be a cam or knock sensor. are their any trouble codes.

Testimonial: "Thanks very much. I also will check the mass air flow sensor. "
try removing battery and cleaning all the ground under the battery tray and check main ground wire from battery to engine

You may have some contaminated fuel,use a additive called heet,for moister,and lucas fuel treatment,these are premium additives,do not just use any brand,these I know will fix the problem if it is in the fuel.
