You don't really need INPA to figure this one out. Say you suspect that injector 1 is bad because you are getting misfires, but you are not sure:

1. You swap the coils and spark plugs between cyl 1 and cyl 4.
2. If the misfire moves with to cyl 4, then its the coil or the spark plug
3. If the misfire remains on cyl 1, then its the injector

Thanks for that....was curios as to what depth and type of detail inpa would give on the currant condition of the injectors or if there are any adjustable parameters other than coding...what is the name of the screen in inpa for this?

If a code was thrown, it would be as straight forward as you say. But what if the injector was not bad enough to cause codes to be thrown? Is it possible that performance can be impaired without a code being thrown?

Yes. Another option is to let the car sit over night and pull the plugs the next morning. Check each plug to see if it smell like fuel, which is an indication that the injector is leaking in that cylinder.

I just changed one of my injector and coded, car runs with no misfire but the flow rate is still the same on inpa? Am I suppose to calibrate it somehow? Thanks

Will this work with Windows 8? I set everything up as per the pdf instructions and when I go to open INPA I get the api32.dll is missing error message. Everything in system properties is correct.

Send a message via AIM to aflatau
I can't even get the INPA software to run right, All I am getting is a bunch of ????? marks under the info menu for the INI path,ecu path and interface.
