I'd start by having the tires balanced and remounted. Rotating them wouldn't hurt either. Start there.

Sensors do not need to be recalibrated , the ecm should have the codes cleared . Then turn the ignition system on with data reader hooked up to see if sensors repaired the fault code.

There are two possibilities...

  1. The crankshaft and camshaft sensors are not properly synchronized to each other. This is a procedure that must be performed with special tools.
  2. A bad alternator diode can cause this code to set due to voltage ripple. Have the alternator/charging system tested.

position sensors have little to do with rough running engine
items like bad injectors, problem ignition control module, fuel pressure , HT leads valves, vacuum leaks all contribute to rough running
best run the fault codes first to determine what area to look at and fix the reported faults

Do a Web search under the terms (Your make, model, year vehicle) intake manifold runner. Or intake runner control solenoids, rods, etc. You may find Youtube videos.

The runners are sandwiched under or inside the intake manifold. Some had plastic clips which crumbled and the operating rods became disconnected. Some runners stuck too bad for the rods to move them.

That car has a lot of lights for a stop light. Maybe they require more than one fuse and/or relay.
Hope this helps.

try tapping the wiper motor, with it turned on, with a hammer if it starts the motor is worn and needs replacing. you can try attaching a separate ground wire to the wiper motor if it runs then the motor has lost its ground and you can run it this way.
