Default Tried to fix a single misfire....

So...
Bought new plugs and wires and a second hand set of coils to fix my P0302.
Pulled the manifold (and mess of wires and vacuum tubes) replaced the coils, wires and plugs. Put it all back together and VOILA!!

P1300
p0300
p0301
p0305
p0306
p1884

Runs worse than a crashing B-52 Bomber....

Definite misfiring, stumbling, Lack of power and quite the backfire coming from the intake!!!

What the hell did I do?



On top of everything, I accidentally auto downed my driver's side window.
Bam, won't come up. Pulled the whole regulator assembly and brought it inside.
All the Nylon wheels look fine, the welds that go to my knowledge are fine. Moves down but only goes back up maybe 1/2" and jams....

Who's plugs and wires did you use and why install a used coil set? I would start with reinstalling your old coil pack.

I pulled a set of what I thought were NGK wires to replace with equally cheap-o' wires. Come to find out they were STI 8mm. Hmmm.

Autolite Double Platinums, and Advance Auto brand wires.
The #2 Spark was weak. Reddish/orange not Blue
So I went ahead and replaced the coil pack.

Swap back to the old coils and double check you plug wires to make sure they are routed correctly. It sounds like you mistakenly crossed them. Search the forums for the firing order diagram. It's a good one - someone took the time to edit the rendering to give it the perspective of an onlooker instead of the POV of sitting behind the steering wheel.
