1992 Toyota Corolla 4 cyl Front Wheel Drive Manual

hi yhanks a lot. My car still fail to start after running. Then I try many times and push hard on accelerator. It starts. Backfires, knock and then become normal.
while canking I smell petrol from the exhaust.
my mechanic wants to change all engine wire. Coolant sensor was faulty but now after erasing there is no code.
can it be also a problem of shime and untuned valves.
next time my mechanic wants to tune the shimes also.
Do you

I would replace the coolant sensor if it is bad. It is not unreasonable to perform a tune up on it, wires, cap, rotor, plugs, PCV, fuel filter, air filter.

The valve shims would only need to be changed if the valve shim clearence is out of spec. If shim clearence is out of spec, the valves will make a ticking/clacking noise.

This is checked on a cold engine and requires a special tool set.
