Well the car was running fine before I put on these mods. The mods I did were Throttle Body Bypass, Porting of the MAF Housings and de-screen, and a Whisper Lid. All were done at the same time then driven.

I started the car and all was fine. Gave it a couple good revs too. Then I drove it around. I drove it for about 10 miles letting the RPM's go no higher than 3500. Then I got on the freeway. I got on in 3rd gear at WOT, it got up to about 4500 rpm then went into 4th and continue WOT up to about 75mph. I then put it into 6th and continued driving. I looked down and the SES light was on.

Me thinky it's the porting of the MAF housings that set it off and probably messed up the fuel trims near top end. I would get the code read but no one will do it here, not even Autozone, "We stopped doing it six to sever months ago." And I'm certainly not paying $70 for it to be read

I'm thiking it's a "Lean Bank 1" code, or 2, or both

Anyone have any ideas, expiriences? I know I could get ATAP or something similar but that will be in the maybe folder for now. Thanks for listening!

 

I get the "car too lean" SES code as well,

it is the MAF de-screening and the porting that could be throwing your code.

Autotap I think you were trying to say


Changing my fuel filter delayed it for about a month, after I reset it.
