I've been looking through previous posts for similar problems, but they all appear to be related to diesel engines.
I've got a '98 2.0 petrol coupe (auto) that's done 38k and it keeps losing power intermittently. There's no set pattern as to when it happens; I can be doing 70 on the motorway and can feel it stutter momentarily and then it carries on as normal. If I'm stopped, or going slowly, it's more noticeable and sometimes cuts out. This can happen whether it's been running for a few minutes or over an hour.
The ECU warning light does come on sometimes, but not always and I suspect it's fuel related, rather than electrical.
Any ideas as to what I need to check?
