2001 Honda Civic nearly stalls after cold start
I have a 2001 Honda Civic EX. Here's the problem I've been trying to diagnose:
The problem only occurs after the engine has not run for ~8 hours.
After starting, (starts just fine), the engine will go several (3-8) episodes where it will appear to "almost" stall:
The rpms will drop to almost nothing and pushing the gas pedal does nothing.
If the pedal is released, the engine will eventually recover after about 10 seconds or so.
As I mentioned earlier, this process repeats about 3-8 times.
This happens regardless of whether the car is being driven, or it is sitting in park.
Then, after it's last episode, the car runs fine until the next time it has sat for ~8 hours.
I've spent plenty of money guessing trying to fix this. Does anybody have any ideas as to what it might be?
Here's what I've had done recently if it helps:
New spark plugs
New timing belt/water pump
New catalytic converter
Fresh oil change
Thanks
