i bought the car a couple of weeks ago. i dont know everything about the car because i have a feeling the last owner lied about somethings. the car gives me problems when starting cold but none when starting hot. i just changed the coolant temp sensor because i got a code saying it was bad. didnt fix the problem i have a feeling the o2 sensor is bad but im not a mechanic. the car also seems to stay at high temp when driving. nothing to alarming but i was wondering if it was normal. also the windshield wipers get stuck in the up position and wont come down on the off setting. the car has 150000 on the body and the previous owner said he put a new engine in and it has about 50000 now. there is a aftermarket radio in it as well that turns off and when that happens the windows stop working as well as the locks. i would greatly appreciate help of any sort. i leave for marine corp boot camp in 6 months and i want the car in good shape before i go. please help
