1997 civic ex erratic idle
I have a 1997 Honda Civic I've replaced everything except for the alternator yes even the head, valves and ICS! I have a serious idle problem when I start it up it idles about at 1300rpms when I switch into drive it drops down to 200rpms I checked it out with a sensor hooked up to it then it bounces between 300-1100rpms when I start driving it the transmission sticks. Then it usually tries to die when I stop the first time I have to save it by hitting the gas. It acts like this for a while but by the time I've driven 10-15 minutes it idles okay but the steering wheel still vibrates. I have absolutely no idea what it could be and I've taken it to my mechanic that I trust and he is baffled! Any ideas would be a great help!!
