Does this sound like a bad coilpack?

[vdublyou]

Car was running great. Got on it a little bit and come to a red light. Car sounds like a Subaru and has less power. Baby it all the way home and CEL blinks whenever I give it too much gas. Pull each wire one at a time and the car runs worse. Each wire is getting a spark so im praying that its just a bad coilpack. Could it be something else?

I actually cleaned the MAF and TB right before I drove it because I had a P0171 code.

Cleaning the MAF sensor doesn't always fix a bad one.

M thoughts exactly, does it have a delay trying to go into over run decel when running ****ty?

No it has been running ****ty since that episode. The CEL stays constant if I don't give it too much gas. When I go past a certain point it blinks.

It could be a coilpack-caused misfire. The only way to be sure is to read the trouble code(s) stored in the ECU.

Swapped out coilpack for a known good one. Scanned codes and im getting P0301 and P0306 which is misfire in cylinder 1 and 6. I swapped plugs and wires for a old set I had laying around and that didn't fix anything. Next thing to replace is the MAF. Praying that is the problem.

1 and 6 are fired at the same time, I would now wonder if your having a signal issue from the ecu.

Think it could be the GIAC chip? My buddy said MAF or Cam Position Sensor.

A bad MAF sensor is unlikely to cause a misfire code, but good luck.

Cam position sensor?

Cam position sensor?

unlikely unless the chain skipped, is it tossing a code for it?

Nope

A little update. Replaced coilpack and MAF. It doesn't idle smooth, but still has plenty of power. Got rid of the P0171 code, but now I have a P0301 code for cylinder 1 misfire. Changed the plug and wire with the ones that were on the car previous to this set, but nothing changed.

Have you done this with all the wires you tryed. Comp check that cylinder.
