Trying to figure something out... I believe my MAF sensor is going bad...the car at idle will read mid 14's normally like always and then it cuts out and goes into the 20's...

BUT...it never cuts out while driving...under normal driving straight off ECU it will stay in the 14's.

BUT under boost at WOT it will not change...scary...I did a quit datalog...and it seems that my inj duty cycle is low...ill see if i can post the log soon...at around 5k rpms 8psi WOT im at 50%...im no tuner but to me that seems low.

Now what im wondering is this...could the going bad MAF be the cause of all my lean issue's???? This sensor isnt cheap and I've already wasted money with fixing my fuel system pressure issue...tryin to avoid that now...

Anyone experience this?

Utec version 2.4
Greddy TT
440cc
AAM return system

 

why are you still using 2.4?

 

no apparent reason other than just being slow...

Just hope that when I upgrade to 2.8 that i wont have any problems...guess that would be my main concern
