The car stated missing a bit and now after sitting for months starts but will not idle and runs real rough, lots of smoke coming out of exhaust and when I checked the oil it is way over full and smells of gas. Is this just an injector problem or something far worse? Thanks in advance Scott
SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse
You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.
SOURCE: Check engine light on
There are three kinds of gasoline engine misfire scenarios, first there is the "under load" misfire and there is the "at engine idle" misfire, and finally there is misfire continuously. All engine misfires exist because one of three things has occurred. First, a cylinder has lost compression, a cylinder needs a certain amount of compression to operate correctly. Second, the ignition system has failed or is failing intermittently, spark is needed at the time of compression to ignite the fuel air mixture. Third, the fuel air mixture is incorrect, proper mixture is needed for the ignition system to ignite fuel properly. If any of these conditions occur in the engine, the engine will misfire.
1. Low or no compression can be caused by
a. burned or leaking intake or exhaust valves
b. worn or broken piston or piston rings
c. worn out camshaft
d. wrong weight motor oil was installed holding the cam followers from adjusting
e. broken valve spring
f. failed head gasket.
2. Ignition system has failed or is failing
a. spark plug has fouled or is worn out
b. ignition coil
has failed
c. spark plug wires have shorted
e. engine control module coil driver has failed
3. Fuel/Air Mixture is incorrect
a. vacuum leak at the intake manifold
b. fuel injector has failed
c. EGR valve is stuck open
d. mass air flow sensor has failed
e. oxygen sensor has failed
f. air intake boot is cracked
common problems:
1. fuel injector has failed or is failing
2. spark plug wire has shorted
3. spark plug is worn out or is cracked
4. ignition coil has failed is failing
Testing a coil on the car is pretty easy. No special tools are required. Just remember to be careful, the amount of electricity generated by your ignition system can be dangerous.
If your coil is already off the car, or if you would like a more specific data-driven test, you can bench test your coil. To set up the test, remove one spark plug wire from its plug, then remove the spark plug using a spark plug socket. Next put the spark plug back into the spark plug wire. Be careful not to let anything drop into the empty spark plug hole -- very bad.

ENGINE MISFIRE
There are few possibilities that can cause engine misfire
issues. It can be issue with spark plugs or faulty spark plugs. Also get the
compression test done for cylinders. If any of cylinder shows low compression
then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.

For
car not changing gears it can be shifter assembly issue, or it can also be
transmission issue. Get the shifter assembly inspected with ignition OFF.
For
more troubleshooting, I suggest you to get the Following help link checked, its
complete step by step procedure to inspect gear shift issues: -----
GEAR SHIFT ISSUES

==========
Car
not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition coil or
injectors getting cracked or dirty and needs to be cleaned.
To
confirm the problem, the basic troubleshooting is required.

Any suggestions as to what to look at first, the car has almost 200,000 miles, should I just replace all injectors? If so what is that process?
