[B]Coil pack? previously-runs rough sometimes no power [/B]

[eeugross2]

Help!! Doesn't anyone have any ideas on this?

Here's what I have and maybe someone has an idea.

94 atx w/120,000mi

just did plugs, wires,valve gaskets, and intake manifold gaskets
new fuel filter

it occassionally has no power-very intermitant-sort of on and off

problem ocurred b-4 60k service

here are the codes
engine on
336

engine off
335 EGR feedback signal is/was out of range - EVR or PFE
211 Ignition PIP signal was erratic or missing - Ignition Systems
214 Error in Cylinder ID (CID) circuit or signal - Ignition Systems
216 Primary circuit failure - ignition coil 2 - Ignition Systems
232 EI primary coil circuit failure - Ignition Systems
336 PFE sensor signal is/was was high - ">PFE

I tried the cylinder test and it didn't work....running too rough at high rpm to goose it....I got message 538 sytem did not recieve goose test.

I thought it was a fuel problem but maybe it's spark? I had the coil off and tested at autozone. Plugs and wires are motorcraft. Yeah checked wire order.

Could it be the coil anyway?

Right now it runs OK up to abt 3500rpms, but rough above.
Other times it's barely running at all and has no power.

Hope someone can help. Provide lots of details since I'm new to this and just pulled codes for the first time.

Thanks

Sounds like one of the coils is dead or not getting power. I had this problem and it was the plug going into the coil. The silicone gasket was bunched up and didn't let it connect completely. Is the tach accurate when it is running rough? Mine would only read 2/3 actual rpm because of the coil plug issue.

No tach seems ok.

Guess i'll change out the coil pack based on the codes. Since the plugs and wires are new and motorcraft. Had the plugs wires off and back on, so it shouldn't be like your problem.

Thanks for the info.

Anyone else have any suggestions?
