Rpms jumping

[Ieva]

Hi. I have problem with my avensis 2.0 (2007) petrol engine. When outside cold and wet starting a car rpms are jumping very much and a car is trembling . After a while car is working fine.  We already have changed spark plugs several times. Error codes every time is changing. Last time the codes was P0175, P0328 and P0300. The check engine Light is on in panel. Maybe someone have been the same problem and can suggest solution.

P0175 = System too Rich ( bank 2 )

Reason - Air-fuel ratio is stable after engine warm up but fuel trim is in error ( too Rich # )

Trouble areas - Injector blockage leakage, MAF sensor, MAP sensor, Coolant temp sensor, Ignition System, Fuel pressure, Exhaust gas leak, Open or short in heated oxy sensor circuit, Oxy sensors, ECM

P0328 = Knock Sensor 1 circuit high input

Reason - Output voltage of the knock sensor is greater than 4.5v 

Trouble areas - open in knock sensor circuit, knock sensor, ECM 

P0300 = Random multiple cylinder missfire detected 

Reason - Misfiring of random cylinders detected

Trouble areas - Open or short in engine wire harness, Harness connector condition, Vacuum hose connections, Ignition system, Injectors, Fuel pressure, Mass air flow sensor, Coolant temp sensor, cylinder compression's, valve clearance's, valve timing, PCV connections, PCV hoses, ECM

The diagnostics for all these run into hundreds of pages I suggest taking a subscription on www.toyota-tech.eu finding and printing the diagnostic procedures off and going through them one by one bearing in mind a lot of the test procedures need a suitable diagnostic computer.
