2000 GMC Sonoma 2.2L, If...
2000 GMC Sonoma 2.2L, If I'm driving for a short trip, I don't notice any problems. When I drive more than 30min I start to lose power, the engine rev's randomly, and when I stop driving, it idles roughly or stalls out unless I keep revs up.

Is the check engine light on or does it come on during problem?

Ask Your Own GMC Question
Customer reply replied 1 year ago
it is usually on. When I last checked the code it was for the evap system. Sometimes the light has turned off when the truck is started.
GMC Mechanic: Dan, Technician replied 1 year ago

Check codes and let me know what they are, you can have this done at your local parts store for free. Keep me updated, thanks.

Holy molly that is a lot of codes, erase codes and check them again when they come back. Let me know, thanks.

Is there anything in there that points to the problem I have with longer trips?
GMC Mechanic: Dan, Technician replied 1 year ago

Based on symptoms and codes it sounds like you have a large vacuum leak somewhere. You can spray starting fluid around intake gaskets, throttle body gasket, and vacuum lines to see if idle changes if so look in that area for vacuum leaks. The coolant temp sensor can also cause it to run rough so I'd consider replacing that too. But before replacing anything I'd reset codes and check them after a couple drives and see what comes back first. Keep me updated, thanks.
