why would the cars rpm’s drop really low(500) and shakes the car bad when I go in reverse with my AC on? I’ve replaced the IACV & cleaned it multiple times, not that.

your welcome, I hope I am correct. Do you have symptoms where pressing on the throttle the rpm's rise up without the engine accelerating for a sec or two..? Meaning the rpms go up almost 1,000rpm's then drops down and the acceleration resumes.?
All the time and it feels like it shifts gears when it’s not suppose to, sometimes seems like the engine works harder to get up to speeds. I’ll get a multimeter and test that TPS.

Yes sometimes it seems like it shifts when it’s not suppose to and the motor works harder to accelerate. I’m also dealing with a EVAP issue. I’ve replaced all parts of the EVAP system but it’s still throwing the code after 300 miles
