HONDA GP 5 Stalling Issue

[mightymicra]

Hiii,

This GP5 came to our workshop and seem to have a issue with idle and sometime while running it suddenly feels a loss of power and stops. Then when you try to crank but it will not start then when you fully turn off the system and then restart it starts fine and moves. The car has done over 100k and haven;t touched. We did a general EFI cleaning and hoped it would clear out. No engine codes were given. After the EFI cleanup the car ran fine for sometime but after about two days same thing started. My guess is may be the ignition coils kind a give up when they heat. (Not sure, just a suggestion) . If you guys have any idea appreciate sharing it with us.

Regards  

TIA

The Electronic throttle is run by a motor. What will happen if motor malfunctions for some positions (specially in idling position)? It will not be a big issue for high RPMs but will affect to idle RPM as the opening size is too small. 

Just a guess only.....

Hii,

thank you for your input. Any suggestions how to check ? The thing is it is intermittent.

how about fuel pump/fuel regulator

I would recommend checking the fuel pump. However, this should record an error related to low fuel pressure if you scan with an OBD. What's the scanner you used
