Hey guys; every time I begin up the on-ramp to the interstate the car bogs down and occasionally other places. I have no codes or pending codes. I know I have the oil leaking into the plug tubes issue and wonder if it’s this since the car is uphill on on ramp or is it a coil pack possibly beginning to die. I’ve located two new valve covers but jeez expensive, $585. Also, the car idles and runs at 196 degrees almost always, but someday sit stays around 201-215.. this normal?
