The .5 primary reading concerns me a bit...

Why is that J Wikoff? Well I did order new ones, I pick them up tomorrow. The second one really concerns me too because it was way too loose and inconsistent. I never did get a clear reading off it.

All the coils I've measured had a primary resistance of .8-.9. I've never seen one that low.

I am replacing them tomorrow and I will keep the one good one as a spare. The new ones are MSDs so it should take care of some my rough idling and some other problems I think the coils have been causing.

I replaced the coil packs and a lot of power came back. But now that I'm Firing right I have noticed that some things have gotten worse. I apparantly have a clogged catalytic converter. I am getting that replaced ASAP so as not to ruin things, hopefully this weekend.

One thing leads to another......

Yeah but this one doesn't surprise me. I had a leaking upper intake for awhile. I was burning mine out the @$$ and with not always firing on all cylinders I was probably blowing out some fuel, so I'm replacing the cat and O2. Then all should be well, I think.
