Car has vf tvs kit. Pressure at idle is 57-58 or so. Seems steady at idle, and when the car is turned off, it takes quite some time for the pressure to return to 0. At least 20-30 minutes (haven't really timed it.)
I pulled the plugs, they looked decent, light peppering if any. They were however a 6 heat range (gapped way too far) and looked a bit hot. I put ngk bkr7e's back in it.
Feels great accelerating with 75-80 percent throttle. So, I'm hoping that it was some combination of bad gas and/or the plugs. But, I'm a little timid to go back wot to confirm one way or another.
