Hello my name is ***** ***** am I speaking with?
What is the history on this engine, have you ever seen it make full power under a load personally?
How old is the fuel?
Does the alarm work, does it beep every time to you start it?
What code scanner are you using?
Are you using Diacom or the hand held techmate?
The techmate is something that you really have to know how to use. Are you qualified to use it? Do you know how to read the live data on the tool?
Have you done a cylinder drop test via the techmate to see if any of the cylinders were not firing?
Does the "gear position" say On or OFF in the techmate when you shift into forward gear?
It should if you have the correct version...
Hello, my name is***** you still require assistance on the engine?
There are no additional charges to continue with me. Your original question fee is still good.
Yes, I have seen it. There can be several causes for this. Have you tried to swap the shift switches from one engine to the other to see if the issue follows it? Seems odd that when you unplug it, the engine will rev normally.
Also on the horn testing beep. You will need to get the alarm repaired to see if you are getting a fault.
You originally wrote that there are no codes that would effect this.. what were the codes that you saw?
Are the butterflies actually opening all the way still?
Have you looked to see if both sets are opening. I have seen one where the second set of butterflies would not open.
Do you know the serial number of the engine?
Thanks. I will pull up the correct diagrams and also check to see if I can locate any bulletins on the engine.
thanks, ***** ***** the engine, what is the MAT, MAP and Baro readings?
Lets see what the DDT says and go from there.
