i have a b16a2 in my 92 sedan running with the stock gauge cluster and everything was fine until this morning. i was driving on the highway when i noticed that my cd deck was turning itself on and off. i drove for a little bit more then the gauge cluster started acting all crazy and shiat. when i pressed on brake the mph dropped from 65mph to 0 then went back up to the regular speed again. when i used my signal the rpm dropped down to zero every time the blinker came on in the dash. i just recently put in some new spark plugs and changed the oil. anybody think they can help me out? right now i'm kinda leaning towards the battery, ecu chip, or the fuse.
