If you have an air leak, you should be able to hear it.
Stupid simple question: Have you checked for a fouled plug, or have you made sure you have the right gap/hot for your car with your supercharger?

You're certain they're the right plugs and that they're gapped right? You didn't drop one or bang one and mess up the gap? I've done this, and had a very similar problem.

Did this all start after installing the bloser?
Fuel quality? did you try bumping up the octane? Misfires are sometimes the basics. check all the plugs plug wires and coils for proper condition, a cyinder leakdown test and compression test, bad valves and/or seats can cause the same misfire/surge effect. Is this at low rpms or all rpms or mid to high rpms? High cyclinder pressure due to boost can require a hotter spark than the OEM can provide. High compression/pressure engines need hotter spark to keep the fire going on the plugs. Just throwing out ideas but stay with the basics before eliminating the deeper harder to solve areas. |

What are your fuel trims doing? Are they showing a vacuum leak?

He just said I have an air leak. He tuned it for the proper trims. That's all he said. And he told me I have an air leak. Ok. Meet me at the shop. |

Do you have a scan tool? Plug it in and see what is up with the O2 readings and the fuel trims. If you are getting unmetered air into the system then your O2 should be reading lean and the computer should be adding fuel to enrich the mixture. |

Ok. Random misfire is nothing to play with on a supercharged car. I take it that's not happening now? No more codes?
I'd like to see some logs from your scan tool. The fuel trims being mentioned can point us in the right direction if there is a vac leak. Like was mentioned, if un-metered air is entering the system, the ECM will try to compensate for it by throwing fuel at it. You should see very positive fuel trims. Did you ever have a canned Magnuson tune in the car? If not can you load it and see if the results are the same? Were the plugs you took out of the car in there with the supercharger installed and this problem occurring? If so, take close up pictures of the tips of the plugs and post them up for us to see. I'm not convinced it's an air leak.......yet. I'd expect to see high idle with an air leak, not a hesitation like your showing in the video. Take some video up around the engine bay...specifically around each head and post that up as well. Finally, 6lbs of boost or ? |
