Did you have the fuel filters changed recently? It sounds like you had air in the fuel line. I get this once in awhile after I change my filters and the air has to work out of the lines. Usually you have to cycle the fuel pump a couple times. push the start button to place the vehicle into run mode without pressing the brake. This powers the fuel system to pressurize. let it sit for about 20-30 seconds then cycle off. do this a couple times and it works the air out.2014 eco GC 112k miles...while driving up mild incline...40 to 50 mph...mild shudder with significant loss of power...no check engine light on
or over heating...pulled over and turned off...then restarted and decided to try to make it home...on the way home...a few miles...issue resolved...runs fine.
Your thoughts kindly appreciated?
If this is the issue, it has not kicked an ECL on me so, it sounds similar
