when my 95 civic is idling, the rpm keeps going up to 2000 and back down until the car has fully warmed up. im also getting terrible gas milage lately, i drive very short distances but i get 200-250 km on a tank now. im thinking a sensor boofed somewhere but i have a pretty limited knowledge of cars so, anyone have any thoughts as to what the problem is?
i replaced the fuel filter recently to try and fix it, any ideas?

i had a similar problem over the last few months, i ended up having to go to honda, it was my fast idle thermo valve, i guess the port was stuck open so it was getting more air or something cause the idle to spike, also the shop i go to said my temp switch was out of range, this is my next fix another 75 bux or so weeee cars are fun
