I have had a miss in my 2.8 for a while now, its not all the time but now and again the engine will miss and then run fine, so just to check I bought the ELM 327 Wifi diagnostic tool. and use my iPhone 5s to read the data or I try to, I managed to get it connected through Wifi but after that they don't appear to talk together, it tries to connect to the car and a yellow light flashes on the Elm unit but it comes up with unable to connect to system (or something like that) is there a specific App for this? Can anyone recommend an APP for my 1998 2.8. Do I need to make anymore setting changes. Help with this will be gratefully received.
Thanks in Advance
Jim
