Ok you guys... saga continues.

I picked up my car this afternoon. My mechanic stated that he still thinks there is an issue as he can wiggle all of my injectors and is recommending new seals and sleaves for all. He said he can push down on one of the injectors and on the analyzer see the mixture change. But he said it should still be drivable if I wanted to wait a bit.

Well as when he started it up I could tell there was still a problem. It was still running rough, the same. I believe him that the wire was bad. But now I don't think that is the cause.

I can still pull out number 5 wire while care is running and no change in the idle. So, for some reason I'm still thinking number 5 is not firing. I pulled out the plug, cleaned it and swapped it just in case with number 4 and no change.

So, not the plug.

However, I can hear an errand spark. And I noticed if the stainess shielding is too close the coil wire near the coil there will be an arc from the coil wire to the shielding. I think I'm getting sparks arcs accross the shielding and wires in different locations around all of the wires...

Could this be grounding of some sort? A bad coil?

Also, I did back date the heat on the same day and the new metal heat duct is like a mm or less away from that number 5 wire boot where it attaches to the distributor cap. I was worried, maybe too close. I shimmed a couple of pieces of plastic in there to see if that made a difference, nothing.

Also, if I wiggle the injector on number 5 there is not change in idle...

Any more thoughts?

I'm going to bring it back to the mechanic and get it in the shop and sit down with them and review what is going on. I'm not down with going after the seals on the injectors right now. I want to see number 5 fire up... Then we can go after the injector seals, unless for some reason number 5 injector is not working at all???

Help!!!!
