Hello guys on this topic i have a 00 civic vtec b16a6 did the motor and battery was out for some time mayb a few months and when i start the light goes of as i drive and the rev picks just above 3000 rpm the light comes on and stays on... What would be the problem??? Help please cause i just under went dropping a valve a busting a piston... Bougth a new motor and put in but using my original intake and sensors, distrabuter etc... Please help dont wana under go another heart breaking stop... Havnt driven the car hard due to engine wearing in... Should i reset it and see if it appears again and then go check it out if it comes on again? Power seeming fine but not sure after vtec... Cause have not driven over 3000 rpm yet
