<DIV><FONT face=Arial size=2>I did several 1/4 mile runs after I installed my
Edelbrock headers and brand new o2 sensor. First and second gear are nice smooth
900mV range ramps. Once it hits third gear is starts descending rapidly to about
400mV and stays down until I let off the throtle. I wish I was at home so I can
show you the exact Diacom graph. I tried giving it more fuel (almost 95 in the
VE tables) between 90-100 KPA but it still does this. The engine runs fairly
well at WOT, but I cant really tune it w/out gettting some accurate info from
the sensor. My old 80K mile o2 sensor in the exhaust manifolds didnt do this at
all. Could this indicate a bad sensor ? I should mention at idle it goes from
40-50 to 800-900 almost every 1/2 second. It does this at light cruise too.
Maybe it's time for a heated sensor ? Still downt explain the WOT weirdness
though since it should be nice and hot.</FONT></DIV>
