Aquired this car from family: Tuesday brought it into Buick to check the high idle - was told throttle position sensor bad, so they replaced it - then got call that car was ready but technician found O2 sensor bad, did we want to replace - said "no" (we did ourselves for $$ less). Now with new O2 sensor in, car now hesitates/coughs so we took out NEW O2 sensor and put OLD back in - car is actually worse than when it went in Tuesday ( they ran diagnostics on it for us originally at that time to come to this conclusion) - HELP, what next - what should we do?
