Disconnecting The Battery Frequently

[MasterDon]

I'm having to borrow the battery of my honda(1.5 Vtec EFI) to start another car these days...,this means disconnecting and reconnecting the battery regularly,sometimes as much as twice a day.

I'd like to know if this is harmful to the car and would I be better off just leaving the car without a battery for about two weeks?

thank you.

This I got from the WEB Q/A.

My car is running rough, but the diagnostics show no fault, what can I do?

Try pulling the ECU fuse. Remove it for at least 90 seconds. The ECU will then “forget” its previous settings and will “train up” for approximately 4 kilometres before it essentially back to “Normal”. (Actually, the ECU is “learning/training” all the time, based on the LAMBDA (oxygen) sensor and the pre-detonation detector, amongst other things.) If this doesn’t improve the roughness, you will need to diagnose the problem in more detail.

Check your spark plug leads.

There may be a fault with your fuel pump.

You could have a faulty ignition coil.
