Hey guys,

Is there any way to use a Scangauge II to monitor injectors, other than the misfire monitoring? I suspect I have a dying injector due to some white smoke and I hate to spend $100+ to do a 5 minute contribution test. Are there any specific x-gauge commands I can use?

Thanks

 

unfortunately NO. The misfire counts don't work AFA everyone here has been able to determine.

 

Crap....that's what I was afraid of.

Thanks

 

Here's the codes as origonally posted if you want to try. As Tim said I haven't heard of anyone having much luck with the misfire count though.

Thanks Rusty, I'll give those a try this weekend and see if I can come up with anything meaningful. I've had the misfire settings in my SGII for a long time, but have never had anything detected, even when I did have a bad injector a few months ago. I'll need to double check to see if the settings are the same as what I have set up. That's a whole lotta numbers to set up, so it might take awhile...

 

I know the torque pro's misfire count at each cylinder is good. $40 vs $100 and you get more stuff too, that is if you have the time to wait the Blutooth adapter to come in

 

Will it do contribution test?

 

Just looked at all the options did not see it. But it does have misfire count for each cylinder.

It is "accurate" replaced the offending injectors at those cylinders and misfires went away. Granted bad injectors are not the only thing to cause misfire readings.

you could do a bubble test too lost of work but also effective. When i get home I'll post link

Thanks for the info.

 

Try disconnecting one at a time. Wait for the smoke to stop. Replace that one.
It may or may not work depending on how it failed.

 

Thanks Cheezit
Since I only notice the smoke driving off from a stop, after the engine is fully warm, will I be able to drive it short distances to look for smoke, with an injector disconnected? Other than there being a miss in the idle, are there any other things I need to be aware of before trying this?

Thanks

 

Nope, ive driven them around the block running on one bank before

 

That's good to know, I'll have to give this a try.

Thanks!
