When it is hot, the van becomes sluggish, then quits. Runs great most of the time. Hot as in over 95 degrees outside, driving up a steep mountain road. Temperature gauge barely creeps above normal operating temperature.
JA: How many miles are on the car? Have you checked the coolant
Customer: 135,000 miles, coolant is full. Van itself is not running real hot, just a little above normal temperature. I live in a mountain town and it has happened 2X. Both on really hot days.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Nothing yet. Check engine
light does not come on. Maybe the O2 sensor coming off the exhaust
is throwing off the computer? I think I have a minor exhaust leak somewhere as well, just started running a little louder when this problem started happening.
JA: Anything else you think the mechanic should know?
