quickly, this is what happened. i took off the stock air intake scoop first section (scoop to where it ends at the stock box, and disconnected before the resonator box below in thefront) hope you know which piece i mean. its the stock scoop piece with a air temp sensor? i think thats whatit is. well i did knock the sensor around a bit while jiggling the scoop. later on i ran the car but no CEL . then a day later i turn on the car and the CEL is on now. i did no modifications really, didnt unplug anything.
only things i did that couldve affected anything are: unscrew the sensor from the front of the scoop, and hit the sensor on the back of the tubing around.
suggestions? something got disconnected? broken?!
and erik if you read this can you help me diagnose on the ecu? someone?
