Here is the hard start and performance troubleshooting chart for that engine to help you and if you have any more questions , don't hesitate to ask .

Customer: replied 1 year ago.
Engine light comes on here and there. When it comes on that's when it has all the extra power. Just replaced the turbo also
Expert:  Andy replied 1 year ago.

Can you please check the flash codes using the engine diagnostics switch located at the lower portion of the dash . Key on , engine off , hold the switch down for one second , then release the switch and count the flashes of the engine warn lamp . Codes are 3 digits long . ( ex. blink, blink , pause , blink , blink , pause , blink , blink is code 222. ) . Then it continues to flash out the rest of the codes in memory .

I will check. Is there a way to turn up the idle to get more rpms for the pto
Expert:  Andy replied 1 year ago.

Yes by using the cruise switch . Turn it on and hold set or resume to raise the RPMs . If it doesnt , it may not be programmed correctly

Customer: replied 1 year ago.

Customer: replied 1 year ago.
Can you put some this in English for me lol
Customer: replied 1 year ago.
What is the. VPM not programming ECM
Expert:  Andy replied 1 year ago.

The best way to go about this in this case is clear the memory or clear codes .

Expert:  Andy replied 1 year ago.

Then road test to duplicate the problem and have the engine lamp come on again . Then check the flash codes again ,

Expert:  Andy replied 1 year ago.

That had a bunch of codes and likely come of them are from awhile back so we need to be sure what we are after here . Can you clear codes?

Customer: replied 1 year ago.
I don't know how to clear them
Expert:  Andy replied 1 year ago.

I believe you will need a scanner to do so .

Customer: replied 1 year ago.
I did. Iam going to try a map sensor
Expert:  Andy replied 1 year ago.

Good call seeing as you had 2 codes for it . It is likely a problem currently . After replacing it , please clear codes again and road test to see if any other issues return . Thanks

Customer: replied 1 year ago.
There was a cut in the hose that goes to sensor .... will clear codes tomorrow and see
Expert:  Andy replied 1 year ago.
