A throttle reset appears to have everything mostly back to normal. Thank you guys for the suggestion, I would have never have thought of that.
Now that I have throttle, car runs superbly with new plugs and IP coils. Acceleration is smooth and improved. I am very pleased so far. I also notice quite a noticeable reduction in valvetrain noise. I will post if I have issues with the IP quads, but happy so far here at the start. |

well this sucks. Was kinda hoping the hood vents would help fix this. So far I have only had the code for the CP on the passenger front one. PITA to replace these. When it goes out I can trigger the code every time at the top of 4th. Normal driving is just fine.

Well I have a possible CP issue now. The past couple of days I've gotten a flashing CEL when going WOT at highway speeds in 4-6th gear. It'll go out after anywhere from 5-10ish flashes. There's also a little studder/hesitation when I first try to get on it. Yesterday on my way home from work It stayed on. I checked the code when I got home and it's a P0301 (cylinder 1 misfire detected). So I swapped the #1 & 3 CPs to see if I can get the code to move to cylinder 3. I didn't drive the car again until today on my way to work. I was able to get the flashing CEL, but not steady yet. I'l try again on my way home. If that doesn't work, any thoughts on what else it could be?
Details on my car: it's a 2013 FRS, 107K miles, of which 105K have been boosted. |

fuel air spark
I'd guess if it's not spark plugs/coil packs it'd be injectors. Did you replace the plugs at 60k miles? |

Here is a little bit of gold for everyone having coil pack issues. I hate to see all the suffering and money wasted replacing coil pack, especially people thinking they need high dollar ones.
I had been throwing miss fire codes on both banks intermittently for many track days. I would just clear the code and continue. It got progressively worse so I decided to investigate. The problem is the electrical plug at the coil pack. It is poorly designed and the electrical connection is not great. I decided to do an experiment and tweeked the male pins on the coil pack with needle nose pliers. I just twisted them 10 degrees or so to preload the connection and put them back on the car. Its been about a year (5 or 6 track day weekends) and I have not had another issue. I hope this works as well for you guys as it did for me. |

Can you provide a bit more info regarding the circumstances? Heavy track use, for example?

I have an Edelbrock SC and just got a P0301 I want to try your trick with the coil pack electrical plug change. Did you take any pics when you tried that?
