Random Engine Misfire
Does anyone know what could be causing this problem at idle?? I'm running NGK BKR7E and I believe they are gapped around .36-.38.
I'm running 60s and a 2.8 pulley and a custom tune.

Make sure your MAF is clean. A contaminated MAF with usually throw this code. Get some electronics spray cleaner from radio shack and spray it. Don't recommend touching the filaments with anything though. The spray usually works just fine.
Otherwise, that code is common for larger camshafts if you have made that change.

The tune has some pretty rough parameters that need some work. I was trying to narrow down what causes the misfires. If anyone has a good tune for 60s and a 2.8 then I would really appreciate it.
