i feel like a dummy when i say this. but i really dont know how to tell if its 8 or 16v. its a 91' 2wd 5spd 1.6L? the temp guage isnt even moving now. since ive unplugged it and plugged it back in. when i unplugged it the engine CEL came on. I plugged it back in. light off. now its on again and the guage isnt moving. what is a dummy plug?
