1988 7MGE Misfire - Stumped!

Injectors. Look at the TEWD and see if those two are paired to one specific line... the injectors are wired in pairs, but I didn't think 3 and 5 were paired to each other.

EDIT:
3 and 5 are paired together, MK3 TEWD On-Line

Hmmmmm...so it appears maybe to be a potential wiring problem then. I'll have to take the sheath off and follow the wires back.

Other than that...what...ECU?

Yup. Test the signal wire, then ground wire, then ECU.
