Plugs are new as of Feb or March but they've had to be cleaned at least once as a result of fouling during initial startup and tuning. They're so cheap that I just ordered a new set; one of the benefits to running a single plug, 87 octane, mild cam engine, I guess.

I have new injectors en route from Joe Smallwood (the ones Dennis recommended and Al confirmed were great) so I'll just change them out.

I also have a stethoscope coming so I can check the injectors. At all of $4 I think it's money well spent.

I'm also going to take a look at TunerStudio's injector testing protocol and see if that can shine some light.

I'm keeping my fingers crossed that it's the injectors or plugs as these are easy solutions that don't really cost that much money. An electrical or ECU problem would be not good.

I have a road trip coming up on 10/7 so this mother better be humming like an a cappella choir by then.

One of the nice things that came out of yesterday was that the tuner was really impressed with how much I actually knew about EFI and this car (I know, I was shocked too). He offered that when I do get the issue resolved he'd let me bring the car back to the dyno and allow me to run the car while he was monitoring. He felt that I could handle it on my own with a little guidance and supervision.

In other news; leather ordered, fabric ordered, new sewing machine needles ordered. Can't wait to get started!
