okay, so im sure somebody has had similar symptoms, but i just want to be sure and get some feedback with the codes i pulled.

p0102 - MAF sensor circuit low frequency
p0103 - MAF sensor high frequency
p0100 - MAF sensor circuit insufficient activity

and the one that bothers me:

p0234 - turbocharger engine overboost condition

okay, so obviously the MAF codes... clean maf.. check wiring/connection.. i got that.

but the overboost code? could a faulty maf/wiring cause this.

also, my symptoms were odd. Car was driving fine on the highway.. got off the highway, after going from a light it felt a little ''sluggish'' still drove fine, would just make absolutely 0 boost no matter throttle position. then after a couple minutes it was normal again. this happened maybe 10 times. and then the CEL came on.

any input is appreciated. thanks :]

bumping this because it's started happening again (haven't really been driving the car much, as I have a beater DD)

only code I don't see anymore is the p0234.

maf could just be going bad. overboost issue could be caused by maf going bad reading the incorrect amount of air coming into the engine.

Bumping because I changed the maf and problem still exists.any help would be appreciated. What do you think next? Map sensors?

popped a new code today. p0114. intake air temp sensor intermittent.
