anybody have this problem....i hooked up a vtec light and the light has a built in resistor....when its cold, and i mean cold, i get a CEL, i believe its from me tapping into the ECU, and when the temp hits normal operating temp i can restart up the car and the CEL is gone, is this normal? i haven't really ran a test to see what the CEL is though...

It shouldn't be from where you tapped it. Sounds like ect(engine coolant temp) sensor maybe.

but it has only been doing that since i tapped my vtec wire into my ecu

Ah i see, i have a light as well in mine, i havnt had the problem. Which did you tap?

well mine is an obd1 and first i tapped it into my green with yellow wire, found out that was my fuel pump wire...then i tapped it into my orange with yellow wire....

You should've tapped the orange/white vtec solenoid wire. I used one of the the clips with a metal bridge tap to tap them.

yea, that's the one....haha...i cut the whole wire off and tapped it in that way, but tomorrow i am going to use heat shrink on it, maybe that will help....but i guess its nothing bad though, it has only been throwing me that CEL because its been so damn cold in WI. its been below 28 degrees this whole week and gets colder....
