Celica Forums General Discussion Engine and Performance intake cel

just installed injen cai last night took about 2 1/2 hours everything went smooth got noticable gains and no bogging yet but today when driving around a threw a cel... i read on the forums that there is an extra plug in somewhere not mentioned on injens install guide or EC for that matter for the 04's (gts) wondering if anybody knows what it is and ill see if its the problem if not i guess ill just have to clean the MAFS and all that other crap. thx

yea clean it but it might come back a week later. My car is messed up because the CEL is always on. IT also came on after installin my TRD exhaust. You might get a P0441 code but not sure what to do because there are many things to check out. The extra plug just leave it alone.
