CEL issues
 

Ok so this is car is gonna be the death of me.. Sons car had the CEL on for
primary and secondary O2 heater fault.. had the blown fuse 15.. completed the TSB for that found the wire shorting out.. cleared the light all good for 5 min then we get P0131 code... Use a buddys mt2500 snap on scanner follow the steps O2 tests bad.. replace O2.. good for 5 min then that darn P0131 again... O2 tests good... it better its bran new... follow steps MAP test bad...
replace MAP... good for 5 min.. then here comes the light again... Cold start
with the scanner conneted I show good voltage on both sensors when it warms up I get zero... Sooooo where do I go from here..?????? :cry:
