If the mechanic did something to your throttle body and it dies now not a long after start, it is obvious to me that it only needs an idle adjustment. I would say needs to clean it first, but if the mechanic done it already, just adjust it. I believe your truck has a throttle cable, and the throttle body looks like this: The ugly yellow arrow points at ...

This could be due to a dirty IAC (idle air control) valve. It is a very common problem spot. Clean or replace.

The engine has no power at idle, it would be same as if you switch in gear and slowly release a clutch. Automatic idle control will try to keep it running, and it will vibrate. Some tiny 1L cars with AC needs to turn the AC off to get up the hill. It's a big load. If your idle revs are going lower with AC ON, then you can consider about checking the idle ...

Don't worry about engine damage. The main difference between these 2 spark plugs is the length, the one you used is shorter. That means 2 things: the spark was not created in the best place, meaning you were not burning all your fuel. This is the lack of power you were feeling. there is no chance your pistons hit your spark plug since the plugs you used ...

Probably not. Engines are pretty tough. But pull a plug before you drive anymore and check for mechanical damage. Pistons hitting plugs would not be good. Also double check your plug wires and make sure you've got the firing order right and that all of the connections feel solid.

Possible, but generally air intake and vacuum leaks will often set an error code in the OnBoardDiagnostics (OBDII) system. We're assuming you've read the codes and came up with no faults. If you've not tested codes yet, do that first. Tell us what you found. On many cars like this, there are no error codes set for ignition wiring faults, or spark plug ...

With the hunting idle and the car going 30-35 mph without touching the gas pedal, it looks like a classic case of unmetered air making its way to the intake manifold. One way to confirm this is the problem is to hook the car up to a scan tool and confirm positive long term fuel trim (LTFT) values; with the given symptoms I expect the values to be relatively ...

I recently troubleshooted a very similar issue on a friend's Outlander. Different car but physics is physics. He was complaining of a similar rough idle and occasional stalling when the car would come to a stop. Turning the A/C on helped smooth out the idle. The dealership was tried cleaning the throttle body, which reduced the severity of the symptoms but ...
