Re:Rough idle, no power up hill lots of fuel, help please!

So collected the 05 plate Jimny yesterday 37K miles on the 150 mile journey home as car obviously warmed up started to idle very badly, so much so I was having to keep revs above 2k or it would stall but would restart easily and on we would go.

Also could not get above 55 mph, engine appeared to be Erving, but just would not really pull and was really going through the fuel.

Then for a brief 10 mins 100 miles in, everything was great, idle was smooth, pulled easily to 60+ and then normal service resumed.

Any thoughts on where to start to look?

I want an ODB2 scanner/editor any recommended ones from your experience?

Thanks

Check the basics first;
Coilpacks and plugs/leads are a good place to start, after that its cam and crank sensors most likely. Any wiring looking damaged? things like that basically.

Have a look on toolstation's website for their ODB scanner. Cheap, simple and pretty good

Everything Riccy said, but before that check the air filter.

You can get a cheap OBDII Bluetooth scanner on ebay for about a tenner. They're all the same. If you're about the Manchester region you're welcome to use mine.

Thanks for the offer, down south near Newbury unfortunately.

Would any of those issues, particularly the sensors, show up as an error code if I get a scanner?
