atomaro Posted August 17, 2009 Share Posted August 17, 2009 (edited) You should check injector pulse next. This is something you may or may not have equipment to do. Edited August 17, 2009 by atomaro Quote Link to comment Share on other sites More sharing options...

Sounds like you have a defective injector. Get yourself a new or used injetor along with some new O rings. It's the only way to know for sure. I have just had the same problem with a Chrysler product. Quote Link to comment Share on other sites More sharing options...

Read up on "current ramping" of coil packs and fuel injectors. You could have a wiring harness or PCM problem.

YT90SC Posted August 17, 2009 Share Posted August 17, 2009 Don't go buy an injector yet. Move the injector and see if the miss follows it. IF it does, then you know it is the injector for sure, instead of jsut throwing parts at it. Quote Link to comment Share on other sites More sharing options...
atomaro Posted August 18, 2009 Share Posted August 18, 2009 Runnig diagnostics through the OBD will only get you so far. We have a Snap-On Ethos, Vantage and Modis. Typically you need to monitor voltages directly at the injector and not through the OBD port (Vantage). If you have the Solus Pro...you should be able to do this. Look in its trouble shooting section. The original Solus may only be a scanner similar to the Ethos with very limited capabilities beyond code reading.
