MAF codes, lack of boost, help!
We just had 3 feet of it week ago. i popped engine light on high rpm in 2nd gear today. p0103. erased it, poped p0101 in pending next vehicle drive cycle. erased it. still getting maf codes, anything else? or is it from the intake. i dont think it is cause it never did this before.
Wow. Longterm that high is crazy, but you've been driving like this for a while. You have to find the leak. Post a pic of your hose and TMAP sensor on your coldside pipe.
heres the live data i have recorded, one is at idle, one id town driving sensibly. harsh winter roads makes it a little bumpy may have to pause to see the driving parms from the video.

boost leak tested, found lower map sensor o-ring to be cause. swapped o-ring with another one i had. reset codes, cleared fuel trims, seems to be ok ill give it a bit of driving and report back
check engine light is back. had pending p0103, cleared code, car stalled and acted sluggish. then p2199.
going to boost leak test again make sure nothing happened ( roads are nasty here ) .

erased p2199 and popped up again after a short run for coffee. going to monitor iat1 iat2 and see what i come up with. got a new maf coming hopefully shortly to just get that out of the way.
ok, still having some troubles, was out of the country for a little while an left car parked. checked, now have p2178 as my only code at this moment, also get low coolant light on cold start every time. coolant is at proper level. still getting lack of power, very noticable when cold, did find lower map sensor leaking and repaired with new o-ring. never got nothing done with fuel injectors because they never looked at it, will rebook an they will check for hpfp oil leak an the fuel injectors next visit.
