If your car is hard on fuel, may be a faulty EGR (exhaust gas recirclation). A quick way to check is to either pull the vaccum hose or unplug the wiring harness. If the car stumbles or even stalls, its still working. If your not afraid to turn wrenches, remove it and check and see if its plugged up, you might be able to chlean it but don't use harsh chemicals or carb cleaner which may damage rubber diaphragm inside unit.
U will need and new gasket to install new or old part back on...

No
a 93 tercel which most likey has a the stock 3e-e engine doesnt have an egr system.
just bring the car to the trusted mechanic....
.008 under normal operating conditions.
I have found that replacing the PCV valve AND chasing down any exhaust manifold leaks usually does the trick.
You more than likely have a clogged egr port. Remove the EGR valve and clean the ports going to the engine with carb cleaner.

It is probably your EGR valve causing the check engine light. I recently bought a used 1997 Toyota Celica and had this exact problem. The new valve cost approximately $85 and fixed the problem right away.
Valve clearance is .008 in at normal operating temperature.
its the hose coming off of the valve cover that's the egr valve
how does the 83 tercel thermostatic vacuum switching valve work
