Have the mechanic inspect the idle control valve, throttle position sensor, fuel pressure, and for vacuum leaks.

hey thanks for your quick response, today i took the car to the mechanic he checked on system there are two codes appears: 1.P1403 - exhaust gas recirculation (EGR) solenoid control circuit low voltage. 2. P0342 Camshaft position (CMP) sensor circuit low voltage or camshaft postion (CMP) sensor circuit. 3. P0132 HO2S circuit high voltage bank 1 sensor 1. Apparentely he asked to replace Cam position sensor and Crank position sensor, i replaced after replacing he checked again with computer all codes have gone it says Read engine trouble code, No trouble code, system normal. Hope the problem is resolved car runs better nevertheless i have to wait its cool down overnight and i ll check tomm, hopw it will not trouble me. Thank you.
