Hi all,
I've searched endlessly for a fix or an answer to the problem I've been having. Friday afternoon, I took my car on a road trip. Everything had been checked, and she was in proper operating order to safely make a trip, I thought. About an hour in or so, going down the freeway about 70mph, I get a violent idle out of nowhere, no throttle response, and sputtering until it has slowed me down to idle speeds, thus cutting the engine. This happened about 6 or 7 times total, as I managed to limp it back about a half hour from home, at which point I had to have it towed back to my house. Every time it happened, my check engine light never turned on. It almost seemed like I wasn't getting enough fuel to my engine, like it had been choked dry, but I had well over half a tank. The reason I only could limp it about a half hour away, was because everytime I reached a stop light, if my revs came close or reached idle speeds, it'd cut my car off, no questions asked. So I had it towed, took our weekend trip in my gf's car, and came back today. When I went to fire up my car to see if I could begin diagnosing it, it fired up normally, idled normally, and drove normally. I drove it for about 15 minutes, but nothing strange happened. I am very confused as to what is going on. Anyone have any insight?
Thanks

 

Search "App sensor" that might be your issue.

 

check your battery terminal to make sure it isn't corroded as well
