It started sputtering recently and I asked Honda service to check the issue and they indicated that battery is fine and connectivity seems OK. But today when I started my car, it sputtered again and lost power entirely.

Any idea what may needs to be replaced. I am thinking spark plug, plug wire...
Please help.

 

Or it could be your alternator. Also, check your engine grounds to see if they're corroded or broken.

 

Did they check the fuel pressure?

How many miles are on the car?

What kind of maintenance have you done to it?

Have you ever cleaned the IACV? (Idle Air Control Valve)

Have you checked for any vacuum leaks?

Does the car stall only at idle, or does it stall even if you push on the throttle?

Was the MIL (check engine light) doing anything? Flashing or otherwise on?






These cars don't have plug wires, by the way.

 

Did they check the fuel pressure? No Idea

How many miles are on the car? 161 K

What kind of maintenance have you done to it? 150 K

Have you ever cleaned the IACV? (Idle Air Control Valve) No Idea

Have you checked for any vacuum leaks? No leaks

Does the car stall only at idle, or does it stall even if you push on the throttle? stall on idle

Was the MIL (check engine light) doing anything? Flashing or otherwise on? no light, no indicator ..no power at all.

 

Sounds like a clogged fuel filter. Check or have checked the fuel pressure. Should be between 40-47 psi.

 

If Honda checked the ECU and it was good, as well as the battery, I'd start checking for loose or bad grounds and have the alternator tested. (as noted)



Just a heads up, I remember one guy having his alternator tested and they said it was good. Turns out that it really wasn't.

 

Been there, done that.
