Electric problem ? Help needed

[Silver98]

I have a 1998 RT/10 almost stock except for K&N filters, smooth tubes and SnakeOyl muffler delete.

On my last two runs, the engine starts normal but within the first 10 minutes of normal driving, the RPM needle drops to zero for one second and goes back to normal. the car will hesitate during that second and once it backfired. It will do that twice randomly and then everything seems OK for the rest of the trip.

Any idea of what might be causing this problem ???

Many thanks for your help.

We'll call this a bump, cause this one sound like something for the professionals. My stupid guess... Electronical parts?

How old is the battery? Poor battery really impacts these cars.
Also, have you recently disconnected the battery? perhaps it is relearning?

It sounds like an electrical connector. And the first place to start is the Battery. Disconnect then check the ground. Disconnect the Battery and pull and inspect all the engine, computer and main wire connectors. Often this will scrape off any corrosion they may have acquired since your car was built back in 97.

Thank you for your replies.

The battery was changed last year. I will double-check the connexions again.

I still have the original spark plug wires, could it cause this kind of problem?

There's not much chance it's all the wires with a loose connection, but change them anyway. It has a better chance that it's a coil.
