You should feel a temperature gradient across the radiator (hot at bottom, cooler at top) if the cooling fluid is circulating properly. If not, you are not getting proper circulation. All things being equal, check the thermostat again - if it was installed incorrectly or is faulty (not unusual), it is not opening and will cause this. Otherwise, you have a blockage somewhere in the system (such as a collapsed hose or blocked port at the pump).

Most people miss the side marker bulbs. Check the right side again, notice all the bulbs that flash. Make sure the left side is flashing the same bulbs. If they are, the turn signal switch is bad. I personally would live with it. They are a pain to remove and are pricey.

Start by testing fuel pressure. If not at specs, change filter and fuel pump. Pressure should be high, probably in the 40-50 psi range, any shop could tell you specified pressure. Also check for trouble codes, use a scanner.
