Zetec shuts off when parked
So here's an intermittant problem I have...
When the car is warm and I place it in neutral or park and release the brake (foot off) the car will occasionally turn off. Not stall, but turn off as if I turned the key. It doesn't always happen (usually doesn't) and I have no other drivability problems. No lights or engine codes shown. I have a few ideas as to the culprit...
1. vacuum leak/ brake booster leak
2. MAF problem or dirty throttle body
3. some weird problem with the trans-shift interlock
I'm not necessarily looking for a quick answer, just any ideas that the FoFoverse might have. Thanks.
