A flaky TFI can do all sorts of weirdo things...

Like N2O said.. No fancy plugs... Autolite FTW!

Replaced the tfi and still missing around 3600 rpms. Idles perfectly and revs great just when constant at 3600?

I would swap the fancy plugs for some good old normal autolites... I believe 24s are what you're after.

Have you had your fuel pressure tested? Could be as simple as changing the fuel filter
