1994 geo tracker
My exhaust manifold is glowing red, after short periods of driving.
it is NOT my catalytic convertor, i have removed it and i have excellent exhaust flow, it is running lean, i do not know why, my question is, how can i fix the problem i have of it running lean?
i have no cat, straight 2 1/4" exhaust to a cherry bomb, so there is no restriction. it has a new valve cover gasket and new intake gaskets. not sure what it could be, EGR valve maybe?

No vacuum leaks? has the o2 sensor ever been replaced?
Replied on September 6, 2007
no, there are no vaccuum leaks, i dont think the o2 sensor has even been out of it. they want $160 for a new o2 sensor. would it be worthwhile to pay $40 for a used one?

No, they have reactive material in them and deteriorate from the first time the engine is started

02 sensor is fine, but there is a crack in my header i have found, beside the o2 sensor, could it be bringing in false air?

Yes, it is important that all exhaust leaks be fixed
