I have an 06 3.5L that after driving for a period of time won’t start back up until it cools off for about an hour. After that it runs fine. It’s got 181,000 miles and has a code for something on the exhaust. The mechanic said it was because the catalytic converters were plugged. I’ve also heard it could be the crankshaft position sensor. Anyone else have this issue?
