Just a followup question but if code B0521 is right bank lean, wouldn't a loose maf cause both banks to go lean?
I tightened everything as you suggested in a previous post. The car is pulling a 25 reading on LTFT on the right bank with the STFT adding fuel as well.
Any other suggestions?
These popped up the other day while I was cruising @ 25 MPH intown. I cleared them and they came back again while driving around town again today, two days later.
Any idea what is the primary cause and solution?
I am selling these for a friend. Here are the details:
Wheels are full polished wheels:
2 18x10"
2 18x11"
Sensors are included from 99 FRC.
On a scale of 10, wheels are probably a 9. Minor mounting scars and one has the clear coat scratched in one spot. These had tires mounted on them once...
Numerous sources claim that Z06 goes rich after adding headers. Supposedly to the tune of 11.5 to 1.
My questions is this: Is this a default wide-open reading or does the car go rich initially and then come back to a more favorable reading with some drive time?
