Might try breaking up each problem into seperate issues… Sounds like the engine has no power/acceleration between 50-60 MPH, But the engine also has a rough idle… Vehicle has no heat if fan on high or has no heat above 60 MPH with fan on high?? The blend door actuator temp runs normal? but I thought it didn’t have heat if fan on high and or possibly above 60??? So rough idle, no acceleration between 50-60, no heat on high??? Now when you say no heat on high, do you mean the hot air turns cool on high or the fan stops blowing hot air on high??? ---

Is the check engine light on? Does the check engine light work ? ---

> [@Barry10](#): > > no power 50-60 MPH, OK before 50 and after 60 Unusual symptom. Don’t recall anyone here posting similar symptom. Are you able to differentiate by driving in a different gear at same speed if the problem is engine rpm related vs speed related? I’m guessing either an ignition system problem (e.g. crank sensor) or EGR malfunction.
