Question about Bushnell Deep Space 78-9512 (120 x 60mm) Telescope
There is a good website for beginners with these small scopes at THIS LINK
To start out, try the scope with the LEAST powerful eyepiece (the one with the biggest number) in daylight (but never point it anywhere near the Sun). You need to zero in the finder scope in daylight too, or you will never be able to find objects with the main scope at night. If you got a Barlow lens with this scope, throw it away.

Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
Inspect the downstream heated oxygen sensor (HO2), replace if necessary
Replace the catalytic converter
