Hello all my 91 civic si won't turn over when it gets cold out. Dash lights lite up radio works headlights work. I've resorted to having to use a hair dryer to heat up underneath the dash on the drivers side and then it will start no problem. Pain in the ass when i leave work. In warm weather it starts every time no problem. Also when i put my lights on the RPM's drops and it idles really low. I also replaced the alternator and new belt. Where should the idle be at on a 1.6L? 550 or 650? Any suggestions would be appreciated. Thanks.
