I just installed my auto meter a/f gauge. it reads idle exactly like it should (slightly rich)but as soon as any throttle is applied it pegs at obscenely rich. did I wire this thing wrong or some thing?I have a stock 90 rex dx with a cold air intake my gauges signal wire comes from the white wire on the e.c.u. spliced about 6 -inches from the e.c.u. <_< please help a.s.a.p.
