The beater(91 Civic Lx) has been throwing the CEL and i finally got around to checkin it out.The CEL does not come on immediatley,it comes on prob 10-15 mins down the road. So this is what i have observed -Turn the key to "on " position -pulled carpet up and looked for the blinks. -it did 3 blinks with a pause between each then after the 3rd blink it went right into a consecutive,no pause 15 blink rampage. So is it a code 3 & 15? I want to make sure i am reading this correctly before i go looking for anything. Is it something else and am i reading it wrong?
