As D. Stern responded a while ago, very sensitive to the crankcase ventillation system. The entire PCV system was supposedly checked and Chrysler parts put in, even without asking me. My independent mechanic decided to do a tune-up that even the dealer would not have dared and charged more than the dealer which made me feel quite stupid. But okay. At least he did the PCV valve although I had asked him to do the same thing way before.
Car did run better though. Hoses were checked. Don't know if the throttle body was cleaned, doubt it.
Now I noticed it's still doing this rare but obvious misbehavior. Sometimes at 600 miles. Sometimes at 1000 miles.
Before, it was when the car was cold and had gone a few miles. Now I went about 100 miles and the engine was hot and then it just, while going at slow speed, stalled out repeatedly.
I did not check for a code though. I was a little panicky so pulled into a gas station to do my usual trick which is pour about half a quart of oil into the engine. For some reason, this always works. And I am going for another
600 miles or 1000 miles. It's so strange since I don't know if it's a coincidence or there is some indirect connection. It would help to accurately know the quantity of oil.I find it hard to get a good reading on the oil. I would not be surprised if it's all a coincidence and I am actually not low on oil. Hard to read the dipstick, even if I leave it out to try and get an accurate reading. But I am not down much if at all. If I leave the dipstick out for 10 minutes and then take a reading, it seems to be a little more accurate, as someone suggested.
Any thoughts? Could the crankcase sensor be a little bad? Does that make sense at all? And the little bit of oil throws things into a different mode? Or some electronics are marginal? The car or vehicle, a minivan, has almost
200,000 miles so things are, touch wood, that is quite a few miles and would not be surprised if a sensor or an electronic module are a tad marginal.
