I had Code P0087 that I experiences two years ago that cleared up the next day. It was a one-time occurrence and had not happened since - until yesterday. I was sitting in a parking lot with the car idling and air conditioning on while I waited for my daughter in law finish with an eye appointment. As the car was idling, after about 30 minutes, it suddenly became to run rough and finally died. I let it sit for a while and then it started again and ran fine.
As we were heading home, of course in rush hour traffic, the engine again died while I was stopped at a light. It would start but only for a few seconds. I was terrified someone was going to ram into use but I managed to nurse it to a side road, out of major traffic.
Eventually I was able to get it to my local mechanic (luckily only a few blocks away). They started looking at it today and, as luck would have it, they don't find any problems and the car is now running fine again. They "suspect" the high pressure fuel pump in the gas tank, which is not a cheap repair. However, there is one common factor in both instances of this happening and that is that the outside temperature was very hot (over 100 deg in both cases).
This has me wondering if something that's up under the hood is getting too hot and failing in those conditions, like perhaps the fuel pressure control valve or the fuel rail pressure sensor? The mechanic insisted that a fuel injected car can't get vapor lock, but I know that's not true. While it is very rare in a FI car, it can happen and one of the conditions under which it can happen is when the weather (ambient temp) is very hot and also combined with hot under hood conditions, Both of these situations were in play both times I had this happen. I'm suspecting the Fuel Pressure Control Valve that sits up on top of the engine is getting too hot and the car is experiencing vapor lock. That's just a hunch based on when and under what conditions the problem has happened.
Anyone have similar issues in similar conditions? If so, what was th solution, or any thoughts as to the most likely culprit?
