I am not sure if my Jeep J-4500 has an ignition coil problem. What are the usual signs of ignition coil problems?
Do you have problems starting your car? If yes, then this a common sign that you have an ignition coil problem. When your ignition coil is faulty and not working properly then it may be difficult for the coil to provide sufficient amount of power to the spark plug. If your jeep, frequently stalls or shut down at low speed or during idle, then you might have a problem with your ignition coil that causes the spark plug to ignite brokenly. If you notice that you are consuming more fuel than usual, it is necessary to inspect your ignition coils for damage or corrosion. Misfiring, back firing, loud engine noise, and lack of power are the other common signs of a faulty ignition coil that needs to be addressed immediately.
I cannot conveniently use my tailgate since it was stuck. How should I fix it? It's such a hassle.
For this problem, you will need a flathead and a Phillips-head screwdriver. It is really frustrating to have a stuck up tailgate, so you'd better fix it immediately. Inspect if the latch areas have debris or dirt that can lead to a stuck up tailgate. If you have noticed that there are dirt or hardened dust, remove and clean those areas thoroughly, and try to pull the tailgate if it is already working properly. If not, inspect and open the access panel on the rear of the tailgate to see if the linkage pieces of the handle are jammed or not, and if they are, it's time to work on them using your tools. If one or two clips are broken or if some of the linkage bars are not connected, then that is most probably the reason why your tailgate got stuck. You will know if the problem is within the handle by pulling the linkage bars and when the latches open. But if the latches are the reason, then carefully unbolt them and replace them with new latches.
My brake won't reach a complete stop even if I step on it harder. I haven't bled the master cylinder yet, do you think there's an air in it? What should I do now?
Did you replace the brake lines of your Jeep J-4500? Air can possibly get into the brake lines if you do not bleed the master cylinder when replacing them. It is suggested to bleed them again, and start bleeding from the farthest area of the master cylinder. If a friend can give you a helping hand, let him watch and observe what you are doing so you won't miss out important matters. Keep in mind that your master cylinder must always be full of fluid when you are going to bleed the brake lines. You can also ask your friend to pump the brake pedals several times in order to release the unnecessary air on the brake lines.
