I have a 2002 OZ Rally with 220k on the clock. I had just recently changed the MAF due to a P0102(MAF circuit input low) and now it's idling really low around 300 rpm or so and has no power when accelerating. The engine seems like it's not getting enough air and my MAF is reading 1.14 lb/min at idle. I also changed my upstream O2 sensor and my PCV valve. My spark plugs and coils are fairly new about 8k miles on them. Haven't messed with my injectors yet but that's my next step if I can't figure it out myself. I'm really stumped as to what could be the issue and I'm seeking assistance.
