So I bought a basic LED A/F meter, and hooked it up today. At idle cold it reads nothing. As it warms up a little it starts to rise up to show it leaning to the rich side of the gauge. Once it't warm even at idle, it cycles back and forth about 1 time a second which i understand to be normal only at about 1500 RPM. This is the first time i ever tried to use one of these things. Is this normal at Warm Idle?

I have a bit of a hesitation on acceleration between about 1000 and 2000 RPM. Timing, and idle are set to spec and it runs fantastic cold. Idle is smooth and I don't detect any kind of miss. Exhaust sounds pretty rattly when accelerating. 94 3.0 3vze 5-SPd

THI!
