If so, and the compression test turns nothing up ... it is indeed time to turn some attention to the injectors. Remove them all, (clean injector bases first, to keep crap from falling into combustion chamber) but keep up with which injector goes to which cylinder. DO NOT SOAK THE INJECTOR BODIES, but give each injector-inlet a sideways blast with aerosol brake cleaner. Mount all injectors upright on a work bench and drop a bit of clean motor oil, or injector cleaner, into each injector inlet ... let stand for a few hours. Reinstall injectors but swap locations .... bank #1 to bank #2. Restart and read new code.

thanks 12ounce, I checked the injectors, each one gave me 12.9 ohms each.
as for the cable switching, I don't quite understand what you mean, switch the #2 and #6 cable at the coil? wouldn't that screw up the firing order?

No, that's the point ... on this engine (as many others in the same era) two plugs are hooked to each end of the same coil. In other words, the two plugs fire at the same time (together) ....one while its cyl is in combustion stroke, the other while its cyl is in exhaust stroke (some refer to this as a "wasted spark"). The next generation of engines used the "coil on plug" design which has a coil per plug.

So switching the cables end-to-end on any of the three coils will reverse the current flow through the plugs ... but will not affect the timing.

... and BTW, if you look underneath the old coil that you removed, you can better see the individual shapes of the three separate coils.

thanks 12ounce, I was at a loss here, I called in the big guys auto mechanics, a mobile unit here in SF. they had heavy duty tools to diagnosis this problem. they found it was the #2 injector, you see when I tested then they were cool, when they tested then they where warm/hot...... that's where I fudge up.

so now I an going to get an injector and new O-rings and plan this for tomorrow morning.....I miss my winny

thank you all for your help.

Hope they did not cost you too much. We would have gotten you there eventually .... but its good to get back on the road quickly.

One cannot do without one's Winney!
