Recently my vehicle stereo has been messing up. It sometimes smell a little burnt. It is the passenger door speaker. It sounds as if it's a shortage inside of it. Sometimes the radio dash fades out. The car has hesitates sometimes to start. Once the AC is on the car starts running really rough and you hear a kind of click is hard to explain but I know it's not normal. At sometimes I am unable to run the AC my whole trip. My engine light has recently came on I did replace the coil packs. Engine light is still on.

My car is again in service due to a faulty gas cap. The wire which attaches the gas cap to car keeps getting caught when the cap is be screwed on. Check gas cap light comes on and then the check engine light comes on. This is the 4th time it is in the shop for this reason. I am told I have to check each time I get gas to make sure cap is on properly and that connecting wire is not caught. I don't believe most people have to do this. I believe the gas tank line was installed improperly and therefore it keeps causing this problem. Thank you.
