SES light after MAF, high flow air cap, K&N I just put a new SLP 85mm MAF, the SLP high flow air box, and a K&N filter. I get a service engine soon (SES) light. How can I clear the PCM to not show this?

Well... i would get it scanned first to find out what the code is... but to clear it
either disconnect the battery and leave it like that overnight (actually takes like 10 mins I think but easier to just leave it discon overnight)
or w/the key in the run position remove the PCM Ign and PCM Bat fuses from under the hood, wait like 30 seconds , turn the key off and back on (this may not be required, but I always do it) and then put the PCM Ign fuse back in then the PCM Bat fuse.
Car will stumble at first cause it has to relearn how to idle... if the SES light comes back on then its definetly a problem... My guess would be PO102 (low maf frequency or something like that) or something similar... autozone can scan the code... or if you want to venture down to the FLP dyno day (ubb.mfba.org under events) in naperville I'll most likely have my autotap with me.
