Default Multiple Codes--but still running :)

Hello everyone.

I need to take my car to emissions in the next week and have yet to resolve any of my SES problems.

I am getting 4 codes total and would like some advise on how to remedy them.

Code 18: Cam/Crank Error
Code 23: Intake Air Temperature Sensor Circuit (Low Temperature Indicated)
Code 41: Cam Sensor Circuit
Code 65: Cruise Servo Position Sensor Circuit

Now, my car starts effortlessly, but has a somewhat choppy idle (maybe 50rpm dips up and down occasionally). My gas mileage is HORRIBLE (maybe 18-21 mpg). And the cruise control does not work at all.

Everything else seems to be in good working order, but as I stated earlier, I must take care of my problems to get me through emissions, and to maybe save a few dollars on gas (as I drive a lot).

Can someone please guide me through what I should be doing here (replacing or cleaning parts, buying new sensors, etc.) Thank you so much in advance.

-Steve

Regarding cruise control,when my wasn't working it was due to burned fuse #5 (15 Amp) on right passenger side under dashboard.Same fuse controls some misc. engine
functions. I have 1995 SSEi.On your car it might be diff. fuse #.Check your owner manual.
