Weird scanmaster readings sometimes.
I recently installed new racetronix pump, adjustable reg set to 44psi, cleaned injectors thru the rail by professional and replaced fuel filter. I have new tps and pretty sure my maf wires are clean. How can I get super low 02 readings? I seem to get weird phantom knock even had some with 94 octane thrown in. Thats why just took the knock out. What else could give low super lean strange readings like .6xx? Damn lt1 makes no sense. I have scanmasters in my 99 trans am and in my 1st and 2nd gen talons. They are working fine. Only the lt1 scanmaster seems to give these bizzare numbers. I think will have to dust off my old autotap and see what it reads.
