Hi Vasi,
It sounds like a fuel related issue to me, but I'm sure others on here would have a better idea. Possibly fuel pressure regulator, but these are difficult to test and expensive to replace. Engine temp sensor, if bad, should throw a fault code, and cause the cooling fan to stay on after you switch off the engine.

Is the engine check light coming on? Maybe you could take it back to your Honda specialist, and make some friendly enquiries - he should at least be able to read or check for any stored fault codes in the ecu.

If you want to have a go at fault diagnosis yourself, then to get started you'll need a OBDII reader - either a good handheld unit, or OBDII cable and software, then you'll be able to monitor some of the sensor readings in real time on your laptop PC as you drive.
