hi there my name is tristan slight i live in western australia, australia
i have a 2007 Suzuki jimny m13a vvt which i currently converted to a m18a
engine everything went fine and ran well it has since done about 2000km since conversion.
Today the engine light come on but still runs fine the only thing i have
noticed is that the engine at idle is rough and sounds like it is going to
cut out.
i am little worried that the engine light has come on, does any one know what
tools i need to read the engine fault code on this model jimny as i have
read its a obd2 on some websites and on others it says obd2 doesnt work
with these jimnys.
also how i could fix the rough idle would be greatly
appreciated thanks

Could be a number of things, but did you use the 1.8 injectors? And in assuming you kept the 1.3 ecu?

A cheap ODB2 reader will work to pull the codes. It's the earlier Jimny's that were not OBD compatible.

I use one of these readers (http://www.ebay.com.au/itm/Bluetooth-V1 ... 3f24ad5f6f) and the Torque Android app (https://play.google.com/store/apps/deta ... rque&hl=en) on my 2006 Jimny.

Best bet is to find out what codes it has thrown and go from there.

I used the 1.3 ecu and the 1.8 injectors

i disconnected the battery and light went out but has come back on.
The idle is really rough and sounds like it ganna die it fine when driving and if i rev it its ok.
any help would be appreciated and thanks tim80z i have bought that obd2 reader chears

Which throttle body are you using? 1.3 or 1.8?

- Tim.

[tslight]

using the intake from the 1.3 with throttle body on that is that correct

[jono165]

Is it possible to pull the fault code manually on a jimny like on earlier vitara's etc? You might just need to find out which pin is which on the jimny.

1.3 throttle body is correct. 1.8 throttle body will work at higher RPM but causes a strange idle.

yea all throttle body and intake is 1.3 so i really lost as to what is going on.
when i first turned the car over after change over the car reved really high so i backed the throttle cable off and had the idle around 1000 rpm and it sat there ok but it is really rough now any ideas??

[jimny_timmy]

There was a guy on here used the 1.3 injectors to get rid of the light... 1.3 ecu basically thought there was too much fuel going through or something along those lines?

Go and get the code read at the dealer. They will have a moan about the conversion probably and insinuate that you've runined it somehow, but they shouldn't charge you just to read the codes and then they'll probably tell you what's wrong with it without you having to speculate.

Dealer will probably get a 'running rich/running lean' code. That's normal for that one to appear every now and again after the conversion. I hope they get another code that tells you what is the cause of the poor idle.

Have you serviced the vehicle? Spark plugs etc? If it is running a little rich, it's no big deal imo but you need to keep on top of the service items. Oil/Filter/Plugs.

thanks squibby yea i am waiting for a obd2 wifi unit to arrive and i will read the fault code my self and go from there

i appear to have fixed the strange idle i changed throttle body for 1.8l and is alot better at idle just have to sort out the engine light as that has come back on but idle is perfect now
