If it's not the plugs, try swapping coil packs with someone.

 

Could it be hitting over boost cut if its getting cooler out? Maybe raise the over boost cut psi.

It could be coils going bad too and not producing a good spark.

It could also be a bad map sensor not reading psi correctly.

Or....It could be too much gap on the plugs and spark blowout.

Or or or.......It could be VTEC set too low on a log manifold possibly.

Or or or or or.......It may be too low of oil pressure and VTEC may not be switching over properly maybe.

Last two are a maybe but a possibility I would think.

 

I have a new map sensor so I dont think its that. The gap on the plugs is .30 so i dont think its that. I dont think its the vtech because its the first time it happened and the vtech setting hasnt changed. It could possibly be oil pressure but I'd need an oil pressure gauge to tell. If it happens again ill change the coil packs and in the mean time ill work on getting some more gauges. 7 psi is low and i could go higher however i want to wait until i have the funds to possibly rebuild the engine because when you start putting the boost higher sooner or later the HG is going to blow and then you have to pull the engine apart and since it would already be apart I'd have an inclination to get new everything. Maybe this summer, also im considering gettimg a newer CR and putting a twin scroll set up on it. For now just get my baby running at 100% then on to the next one

The head gasket will not blow if your running stock CR
