Hello my clk 430 randomly started having problems
codes are p0104 p0112 p0120 p0221
car has a rough idle (feels and sounds like a misfire but no code) or random cutout
and pretty commonly I’ll get a esp please visit work shop and car will not move happens when moving or sitting turning car off and on will fix temporarily
Initially I thought it was my voltage regulator
but AutoZone says my alternator is good (not sure how much I trust there test) but my battery was bad so I replaced it same problem
so I used a maf from a junk car (cleaned it well) worked a bit better but still having same problems
can the voltage regulator cause these problems or am I way off
next move is to order cam/crank sensors and voltage regulator
car has 171,000 miles thanks for any help

It sounds like you're dealing with multiple issues that could be interconnected. Let's break down the error codes and symptoms to get a clearer picture:
### Error Codes:
1. P0104 - Mass or Volume Air Flow Circuit Intermittent.
2. P0112 - Intake Air Temperature Sensor 1 Circuit Low Input.
3. P0120 - Throttle/Pedal Position Sensor/Switch "A" Circuit.
4. P0221 - Throttle/Pedal Position Sensor/Switch "B" Circuit Range/Performance Problem.
### Symptoms:
- Rough idle or random cutout.
- "ESP Please Visit Workshop" message and car not moving.
- Temporary fix by turning the car off and on.
### Potential Causes and Solutions:
1. Voltage Regulator/Alternator:
- A faulty voltage regulator can cause electrical issues, but since AutoZone tested your alternator and found it to be good, it's less likely to be the primary cause. However, if the test wasn't thorough, it's worth considering a second opinion.
2. Mass Air Flow (MAF) Sensor:
- You've already replaced the MAF sensor with one from a junk car. Even though you cleaned it, it might still be faulty. A brand-new MAF sensor could be a more reliable test.
3. Throttle Position Sensors (TPS):
- The P0120 and P0221 codes point to issues with the throttle position sensors. These sensors are crucial for proper engine management. Replacing the TPS could potentially resolve some of the problems.
4. Cam/Crank Sensors:
- These sensors are also critical for engine timing and performance. Given the mileage on your car (171,000 miles), they could be worn out and causing intermittent issues.
5. Electrical Connections:
- Check all electrical connections, especially those related to the sensors mentioned. Corroded or loose connections can cause intermittent faults.
### Next Steps:
1. Replace the Throttle Position Sensors (TPS): Since two of your error codes are related to the TPS, this is a logical next step.
2. Consider Replacing the Cam/Crank Sensors: Given the age and mileage of your vehicle, this could preemptively solve potential issues.
3. Inspect Electrical Connections: Ensure all related wiring and connections are clean and secure.
4. Retest the Alternator/Voltage Regulator: If possible, get a second opinion on the health of your alternator and voltage regulator.
By systematically addressing these potential issues, you should be able to narrow down the cause of your car's problems. Good luck!
