How do you test a knock sensor ('86 5ktq)?
the ecu claims that it is bad. Light goes on anytime the manifold pressure is abobe 1.0 bar below 3k rpm, above that speed it comes on at lower manifold pressures; no knock is present. It all started, perhaps coincidentaly, when the cat got gutted.
Does anyone have a used one (good) for sale? a spare.
what sort of voltage do you get at various engine speeds? (vac on dvm)
p.s. not Angela! and no I can't give you a subject!
