“CAR GOES INTO FAIL SAFE EACH AND EVERY TIME IT IS DRIVEN. IT DID SO 19 TIMES TODAY. I CONNECTED A CODE READER WHICH IDENTIFIED THE PROBLEMS AS BEING RELATED TO THE THROTTLE CONTROL AND THE THROTTLE BODY. I PURCHASED THE CAR 1 1/2 MONTHS AGO. PRIOR OWNER HAD THE THROTTLE BODY REPLACED WITH A NEW MOPAR UNIT 4 MONTHS AGO/ 2000.MILES AGO. DON'T WANT TO REPLACE IT AGAIN SINCE THIS IS LIKELY NOT THE PROBLEM.”
