The Lucas brand of products are very good.
To clean the fuel injection system on a 1994 Jeep Grand Cherokee, you can use a fuel injector cleaner additive. Pour the cleaner into the fuel tank as per the product instructions, and then drive the vehicle to allow the cleaner to circulate through the fuel system. For a more thorough cleaning, consider removing the fuel injectors and using an ultrasonic cleaner or a specialized injector cleaning service. Always make sure to replace any fuel filters and check for any other issues in the fuel system during this process.
Add a fuel injection cleaner into the fuel tank or go to a garage that has a fuel injection service machine.
No they are not but should be done in conjunction with eacd other. Fuel injection cleaning is what it says to be. Induction cleaning is cleaning the throttle butterfly and the the intake, back of the valve and combustion chamber.
Fuel injector cleaner does not hurt anything,but most fuels already have a cleaning additive in their fuel.
Yes you may its not going to hurt it. Also while you do fuel system cleaner use injection cleaner too.
Fuel injection gives the best air to fuel ratio for best performance and efficiency.
In the gas tank
Yes.
Fuel injection service generally means running a cleaning solution through your fuel system. It removes the carbon buildup and makes the injectors spray more effectively.
Modern fuels have a fuel injector injector cleaner built into them. However I do recommend you use a good fuel injector cleaner such as Seafoam or Chevron Techron once a year.
seafoam you can buy it at any auto parts store it works really poor it in your tank and it does the rest
Pouring the injector cleaner down the throttle body won't clean the injectors. You need to add the injector cleaner to the fuel tank for it to help you. Read the instructions on the container of injector cleaner.
