Multiple Misfire
Hey Fellas,
So I install my new shocks and go for a test drive and wow what a difference!! If you have old shocks, replace em you won't regret it. Anyway so I'm on my test drive lovin the new ride and I hit the ramp for the highway and I put her to the floor WOT and she goes great with smooth power until I hit 3rd gear and the CEL starts flashing at me WTF!!! So as I am slowing down it stays on solid and it seems to drive and run fine, so I continue how to get my hypertech out to read the codes and I got 7 total all misfires P0: 300,301,304,305,306,307,308. So I guess the only two that behaved was #2+3 LOL.
It was recently tuned up with Napa echlin and champ. truck plugs gapped at 45( I run a glass pack and open air filter jacobs C-4 coil) and a 87 octane tune from my Hypertech tuner fuel pump, p/up coil is new.
Drove it today and all was fine???? not so much as a hiccup any ideas guys? Much appreciated

Re-gap the plugs as everyone states unless you are running some kind of performance output coil. Even with my MSD ignition I found that running .042 was perfect for my build which was pretty built.
Could also be a bad Camshaft Sensor (AKA...Pick Up Sensor) located under the Distributor cap or lazy coil.
Reset the PCM as Indy states.
