- Tue Apr 09, 2013 11:32 pm #330367 Apparently I need a .052 gap NGK R PFR6G-13 spark plug. The ones I kept getting that were "recommended" for my car were regular PFR6G's or were 11's and had a .044 gap.

So ordered new correct plugs and a PCV valve because mine was gunked up and old.

I'm running an alpha series 66mm TB with the GSR bracket and cable on mine.

Going for a chipped P28 since I'm running the Skunk2 Mani.

- Sat Apr 20, 2013 2:41 am #330770 flashed P28 plugged in, Still no start... Getting fuel, getting spark. ECU registers a CEL code 10 when i unplug the IAT sensor, so it's reading something. Unless there's some procedure i'm not doing, I'm stumped. Wondering if it's a bad map, gonna call them tomorrow and see what they say about it.

- Sat Apr 20, 2013 3:22 am #330773 Could this possibly be a bad ignitor in the dizzy? I get spark, and fuel, but after it spins a while the plugs are covered in fuel. swapping plugs does no difference.

You think maybe it's not getting enough spark signal or something? I'm tired, and thinking out loud here.

Edit: Maybe bad coil? I'll try to swap one from my old dizzy tomorrow and see what that does.

Replaced the dizzy cap and rotor in a last ditch effort to see if it was shorting out from coil to rotor after checking the ICM and replacing the coil with a known good.

It fired up after purging the fuel out from being flooded. Cranks up and drives each time now.

Tonight, it's a celebratory Jack/Coke and I tweak the TPS, idle and fine-tune the timing tomorrow morning.

Also of note: The VTEC crack scared the shit out of me noise-wise and rolling over the 9000 RPM mark with the tuned ECU is orgasmic...

- Mon Apr 22, 2013 4:45 am #330827 That means your cat converter is toast. Dumping a bunch of fuel in it will kill it pretty quickly. You should replace it cuz it's partly bricked up. It could ruin your muffler as well.

Yup, I agree. But at the same time, we cut and refitted part of the exhaust a few inches behind the cat in order to line up the header properly and the violent shaking might have knocked a bit loose too. I'm gonna check it out in a few weeks when i can down the car again to rebuild the transmission.

Might just gut it and put it back on, anyone wanna buy the internals? lol
