Howdy guys, i've got a 96 lt1 firebird formula with 156k on the clock, she just started running poorly and ate a quart of oil in a week, i scanned her and we have the following codes p,0100,p0134,p0141,p0154,p0400,p0412,p1441

The O2 codes were present prior to this issue so were gonna just ignore those for now (I'm sorry)

What were gonna look at is the p0100 first, im gonna check the voltage for the MAF pigtail via the pinkwire (Thanks Shbox!) then i'm gonna proceed to take the system apart and check for any oil in the manifold/sensor, i noticed oil coming from the breather on the passenger side valve cover and the oil stem/cap so i am going to assume there is blow-by prevelent i will check for chuffing coming from the oil neck, i will post results and pictures!

 

Well that was lucky, so unplugging the MAF immidiately fixed the idle/running issue and she now runs like factory again, now to see what happened to the maf. i am thinking that our oil has something to do with this, going to test the signal on the maf harness then swap maf will post results.

 

Also the oil all over our passenger side valve cover i am going to assume is from a faulty PCV valve, going to remove the pcv then check for flow.
