Automatic choke problem?
There isn't just one reason for this symptom. It may or may not be related to the recent head repair. Inspection of the engine compartment will be needed. I would first check to see if the engine light is on. If it is then the codes will need to be read. The codes could hold vital information to help get down to the bottom if this. If not, then look over the engine. Look for pinch, damage, pulled, or unplugged wiring and vacuum lines. your idle issue could be something simple. Maybe the mechanic accidentally put the spark-plug wires on wrong. The more tests that you run and the more information that you provide, it will help us narrow down your search. A large part of the engines functions are electronically controlled. It is possible that there is a failure within anyone of the many electrical parts. It is also possible that there is a mechanical failure. Low oil or fuel pressure, engine running cold, clogged filters, or a blockage inside the catalytic convertor, these could all be suspected and related. I guess the long and short of it is that yes, I have some ideas but no, I'm not sure which one applies to your car. Please write back with what you have checked, what you want to try, and any ideas that you have. Hopefully we can get down to the bottom of this soon. good luck.
