- My model of MX-5 is: 2000 Icon 1.8
- I’m based near: Thame, Oxon
- I’m looking for technical help or recommendations on: Engine stumbling and power loss
This is a problem of an engine stumbling at idle, and running erratically when crusing at a steady 30mph.

It’s very low mileage, and back in March it had a service at a Honda dealership, since when no problems have been noted until just the other day. I wonder if this might be temperature related in some way, due to our current heatwave as it came on pretty suddenly when the weather got hot?
In the service the following was done (among other checks):
- Oil and filter replaced
- air cleaner replaced
- plugs replaced
- valve clearance adjusted
- timing belt
- transmission fluid
She also got a new camshaft sensor in oct 2020.
Grateful for any suggestions on where to begin! (Current plan is to pull the plugs tomorrow and see if they show any useful pointers).
