Misfire cylinder 5! Suggestions please
#12
Update2: after switching the plugs 3to5 I headed home. Something on the way home misfiring when I got on the gas a bit. Get home scan and it's still cylinder 5. Didn't get a chance to buy the Lucas so will try to get it tomorrow if I get a chance. At this point I'm leaning towards the injector being fouled up or going bad.
I don't know if that makes sense but not sure if injectors will just die or gradually die.

So I finally had some time and ok weather to get under the hood and try some things. Luckily I didn't need to drive all week.
So I took 3800's suggestion and swapped the coil packs 2/5 to location 6/3.
Checked to make sure had no codes and hit the road.
Punched it misfire, pulled over checked the code and sure enough cylinder 3 was the one that misfired.
Looks like the coil pack is the culprit.
I was looking to replace all of them just to know all are new with:
Standard Motor Products DR39 - Standard Motor Ignition Coils - Overview - SummitRacing.com

I had the same problem a couple summers ago. During a 90+ degree day I was on my way to work when my car started running really bad, first the engine light came on, then started flashing while trying to merge on the interstate. I didn't know what was wrong, so I parked it a got a different ride to work. Later drove it after cool and ran fine till warm again. Long story short it was a bad coil pack. Running great since! Glad to hear you figured it out.

3800: I have not replaced yet, just did this today. I am thinking about getting the standard that I put up the link for. I would prefer MSD but when I called Summit they said they don't believe I can use the MSD #8224 for my 2001 3.8 and when you search by make, model, engine size they don't come up.
Vanquishfist: I am very happy to have finally figured out whats been going on and glad to here that yours is running well. I can't wait to get Midnight running right again.

I just looked up your car on the msd website and it's the 8224 that you need.

3800: that's what I thought too then when I called Summit's tech line they said they didn't think they would work. Thanks for looking that up I'm definitely going with the MSD's over those standards.
