Hey guys. My truck recently has been idling very irregular and as of last week will idle then putter out and die. Nothing has changed and I'm really confused. I checked with a scanner and these are the codes that came up. Do you guys have any ideas where to start?
M- Misfire Monitor
F- Fuel System Monitor
CC- Comprehensive Component Monitor
C- Catalyst Monitor
EV- Evap System Monitor
O- Oxygen Sensor Monitor
OH- Oxygen Sensor Heater Monitor

 

Those are not codes, those are telling you what monitors are supported on the Vehicle.

 

Well when I plug in my Innova-3030f the yellow light comes on and gives me the initials for all the problems I listed above. So I checked the website and found out what they stand for. Was I using it wrong?

 

You tell us. Here is an instructional video.

 

I probably didn't do that right. I'll check tomorrow! Thank you.

 

Good luck! Keep us posted so we can try and help.

 

Thank you! I appreciate it!!

 

Sounds like you have a clogged fuel filter or bad fuel pump. If your check engine light isn't on by now you probably won't find any codes. Check your fuel pressure, if it's not above 50psi with the key turned on you have a supply problem. If it bounces wildly, you have a bad fuel pump or bad regulator.
