Question about 1997 GMC Jimmy
PO102 = mass airflow circuit low. Means there's a problem with the mass airflow sensor or circuit. Could be the sensor is disconnected, dirty, or faulty. PO340 = camshaft position sensor circuit. Could be ground wire disconnection, camshaft position sensor failed, PCM is failing, or even the crankshaft position sensor has failed. Good luck. Let us know how it turns out.
