Misfire/stumbling
Misfire/stumbling
When it rains... It pours.
I just got the truck back together from 6# (from 4#), h20 pump, new plugs, new tstat, took blower/ic off for oil cleanout, and new chip reburn.
Now the truck seems to be missing. It's really noticeable when you give kick the throttle body level up a bit and let it come down from that. On the down slope it seems to stumble towards the end. It's aslo noticeable at idle. I don't mean it runs like a helicopter, but something is not right.
I did check all the injector plugs (i don't remove them but i checked em anyway), and all the coil pack plugs. All are seated properly. Also checked the PCM to make sure I didn't bend any pins.
One thing I'm unsure of is that I used dielectric grease (the white stuff) inside the tips of the coil packs when I reinstalled them. There is a coating of it on the tips and the 'coil'. With normal plug/wires this would be ok. Is this not recommended?
Any other ideas?

Come to think of it... The front right plug looked very wet when I pulled it out to check it. How do I check that coil pack, or, how do I check the coil pack plug there? Can run the truck with that plug disconnected and hook a meter up to it?
ALSO, the front right plug that I took out was all crusty... Not horribly, but noticeable.
Does this sound more and more like a bad coil pack?
