Auto repair

[Nalt]

Are any of y'all auto mechanics? I have a 2006 Dodge Durango that I bought used several years ago with very low mileage. We bought it to let our middle daughter drive it to high school and college. Occasionally when she would come to a stop the engine would just die. Put it in neutral or park and the engine would easily restart. Over the ~ 3 years that she drove it the problem started happening more often as time went on. Later she bought her own car so I started using it and the problem continued to worsen. It sometimes idles really rough. I have had it die on my while driving at 70 mph on the interstate. It still restarted just fine.

We have had all four oxygen sensors replaced as well as either the crank or cam position sensor but I can't remember which, just not both. Even replaced the catalytic converter but the problems continue.

Any thoughts about what is going on?

Any OBD2 codes?

Any OBD2 codes?

The codes have always pointed towards the o2 sensors.

Leak exhaust leak? What kind of code? Rich? Lean? No signal?

I know exactly what’s causing it.

Dodge

That was actually my first thought. :)

That being said, the trucks are the best of their products.

crankshaft position sensor

crankshaft position sensor

Possibly I suppose. Do you know where it is on the engine? I believe I replaced the cam position sensor and it was on the front of the engine on the passenger side. It obviously didn't make a difference...

Possibky..

Do you know the specific codes?

It has been several months since I had the codes read. Don't remember what they were. I'll try and get them sometime this weekend.

it really does matter which ones. I found that slight leaks can be compensated for by the O2 sensor to a point. people seem to miss those and also small vacuum leaks.

Get the adaptor plus the smart phone app to read and reset your codes

Doesn't a bad O2 sensor just puts your PCM into limp mode? It will play hell on your gas mileage but won't strand you.

Replace the plugs, points and condenser....air filter too....blow it out on the interstate for about 59 miles with premium gas then trade it in on a Toyota

Points and condenser?

The flood water it sat in for 3 weeks is catching up to you. ;)

For so many years we got by with a Haynes manual, a few basic tools, a shady spot to work, and the phone numbers of all the “you pull it” junkyards in a 100 mile radius.

Then they started putting computers in cars.

One of my high school summer jobs was rebuilding alternators and starters. I think I’ve fixed or replaced everything on a car except for a transmission or an axle.

I used to help my friends and family with their cars too. I had a formula where I carefully calculated exactly how much it would cost and how long it would take for the repair. Then I’d double the cost and triple the time and come remarkably close to the reality.

I don’t mess with modern cars. Not worth it.
