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

Hi,

Go with Riccy 's suggestion first and give everything a check over. The ODB reader is a good addition to the tool box, cheap enough, and if you have one worth a look to see if any codes are logged.

What's the story behind the vehicle, the low mileage suggests it's been little used. Has it been serviced recently?
If you have any doubt whilst you are checking items maybe plugs, air and oil filter, engine oil are a start. Then fill the tank with a premium petrol or fresh supermarket with injector cleaner additive and go for thrash / Italian tune up.
This may sort it out if it's been standing around.

After this it's ODB time if not done so already or IAC valve clean.

Got to start somewhere, so start simple. The Suzuki engine is a reliable lump but doesn't like neglect from a servicing point of view.

Good luck and welcome..

Mike

Sounds suspiciously like a blocked catalytic converter. Though the other things mentioned above are also possible culprits.

The mot history suggests it has had very little use each year. A bit of service history but not much, which is not so good. I didn’t pay loads for it, so I thought the verified low mileage and general look did not make it seem too big a gamble. Plus I liked the paint job and the fact wheels, lift and snorkel already done made me take the plunge.

It has clearly been used off road, but seems to be straight and really runs well when it is cool.

Following all your advice I have taken plugs out, bodies are very scorched at bottom of white bits, so just put 4 new ones in. Coil packs all look very clean and tidy so going to leave them for a bit.

Air filter is brand new.

Changed oil and filter just now before rain forced me inside!

Ordered a £20 ODB reader on Amazon will be here later tonight so will plug in later and see what that says.

So it’s not the plugs!

Left it running for 30 mins or so and the issue cam back.

Struggling to find the info on where the two sensors are to do the cold water cooling test. Please can somebody send me a link.

Many thanks.

If it's not putting the engine light on then reading the basic code will not show anything. You will then have to look at what the code reader can report from the sensors. Crank/Cam sensor failures do not normally show up well on a reader.

Cam sensor is behind the head on rear right of engine.

Crank is hidden behind alternator, front left of engine
