What Year/.Make/Model is this?

I really need to know the SPECIFIC VEHICLE

You need tune up,cap or coils,could be crankshaft sensor,camshaft sensor,maybe fuel filter.

fuel filter,tune up,

the best way to fix your problem would be having OBD (on board diagnostics )pluged to your car . am asuming u didnt disconnet your baterry before u started replacing the parts which ,made faul code or codes come on. Because those are very important sensors engine won't start until u reset the codes

Maybe the crankshaft sensor or the camshaft sensor. I don't know what brand of car you are working on. Well I guess if it is old enough that would be the pickup in the distributer.

Let's start with the codes.

Po129 refers to barosensor

Po344 is a code for the camshaft position sensor

Po339 crankshaft position sensor

Po340 camshaft position circuit malfunction

Po335 crankshaft POS sensor malfunction

Po122 throttle pedal position

Item 2,3,4,5 relate to each other that s camshaft and crankshaft position sensors. Since both already show a malfunction code, it would be advisable to change.

Sometimes other codes show up because there is a relation but not that the item is bad.

P0345 Camshaft Position Sensor A Circuit Malfunction (Bank 2) A code P0345 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed
• • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

If you changed the camshaft and/or crankshaft sensor, it will need a CASE learn to be able to run.
