Difficult start, dies when given gas
my 2000 jeep wrangler 4.0 hard to start and really rough idle and when you give it gas it will die out can anyone help me please
Is this a good question?
Start by checking for engine codes . this is the quickest way to diagnose a problem . there could be an issue with the fuel or air input regulated by the MAP or MAF sensors or oxygen sensors . If any of these are out it can affect how the vehicle runs. Check your fuel system . Start by replacing the fuel filter . If you have access to a fuel pressure tester check your pressure on the fuel rail . If the pressure is low you may have an issue with either the pressure regulator or the fuel pump. Its also a good idea to check for fuel leaks in the lines running from the tank . Hope this helps
