Hey, I was wondering if any one on here has ever ran their car w/out the thermostat in it. I replaced my theremostat and now the guage is reading almost FULL hot and then it will go back down to like 3/4 and then back up and so on. Should I just try a new thermostat or take it out...someone on 240sx.org told me that if i take it out it will run in "warm-up" mode and be running really rich. Thanks.
