I have already replaced the MAF and MAP sensors, cleaned the air filter and Throttle body...I was driving my car for prolly 100 miles on the highway and all of the sudden my car decides to go into "engine power reduced" and the CEL comes on. Didnt have one before hand only when engine power was reduced. Stopped disconnected the battery for 5 mins and as soon as I revved it past 3000 rpms, it does the same thing. Let it sit overnight, tried to drive it today and got a mile down the road, it does the same thing. P0069, p0068 and numerous other throttle pedal, MAF and MAP codes...Any suggestions, I'm at my wits end with this junk-box

 

could it have to do with not having an ambient temp sensor hooked up???

 

soooo,... turns out after a lot of frustration and headache it was the barometric pressure sensor. With it bein right next to the oil filter housing it got coated in oil and the nipple got clogged not allowing it to get an actual reading. Cleaned it up, problem solved
