Find the right carb cleaner option from our store to see the difference in the performance of your car after the carburettor has been cleaned of all contaminates.

Carbon buildup from combustion can clog fuel injectors. Fuel Injector Cleaner/ Carburetor Cleaner.

Gumout® Fuel Injector & Carburetor Cleaner keeps deposits from forming on these crucial parts to If the answer to your performance additives question isn't below, contact us by email or by phone.

Armored Autogroup STP Injector and Carburetor Fuel System Cleaner – 5.25 oz. If the filter is dirty or clogged, it will be apparent when you examine it. When cleaning a carburetor of a chainsaw that doesn't start, check the air filter. We simply made sure the dash board lights didn’t go into hyper-drive when we started the rig and let it warm up.This should help you understand that in cleaning the carburetor, you may need to clean the channels for both air and fuel. If you have an Intelligent Tester, you can ensure the mass air flow sensor is operating within spec following the Toyota mass air flow check service bulletin. Screw it into place, connect the wire harness and reattach the engine cover. You will hear a click as it seats past the O ring on the sensor’s collar. After the cleaner has done it’s job, slide the MAF back into place. The contact cleaner we used drys in about 10 minutes and does not leave a film. In order to clean the hot wires we picked up “contact cleaner” from Radio Shack and following the directions, really read the directions… sprayed the hot wires with cleaner. With the MAF sensor removed inspect the hot wires for muck.

You can cover the opening with a shop towel to prevent any dirt, bugs or stray bird poop from falling in while you clean the sensor. With the harness disconnected, remove the two screws holding the MAF in place and lift the sensor out of the the air flow box.

If the connector refuses to release its grip, try holding the clip down while sliding a screw driver between the connector and MAF, gently prying the two apart, careful not to apply too much force (remember plastic exposed to heat, over time can become brittle). To remove the wire harness, depress the clip and give a snug pull on the sides of the connector. Carefully, unhook the wire harness connecting the MAF to the engine’s computer. Once cover is removed, the MAF is exposed in the front of the secondary air flow box. The first step is to remove the plastic engine cover, by loosening the two nuts up front and lifting the cover off it’s hinge. Removing the FJ Cruiser’s MAF sensor for a visual inspection and cleaning is a simple procedure. If you have a few garage tools and about twenty minutes you can clean the MAF sensor, which may solve the issue, if the wires are mucky between cleaning cycles. Manufacturers of MAF sensors recommend replacing the sensor, after all they are in the business of selling them. If the deposits remain and engine’s computer sees an air mass value out of range, it sets an error code… and the dash board lights up like a Christmas tree. Periodically, there’s a cleaning cycle where the wires are heated to a very high temperature to burn off deposits. To ensure a correct reading the engine’s computer takes into account temperature and humidity as well.Įventually, dirt and oily film can cook on the wire creating a thin insulating layer of muck.

In other words by measuring the drop in temperature of the wires (or increase in current passing through them) the engine’s computer can calculate the airflow. As the air flows across the the wires, they cool down creating a positive temperature coefficient (PTC).

The technical jargon behind the acronym MAF involves a constant voltage passed over two heated wires placed into the airflow. As the rig drives down the trail, through the hot and cold as well as humid or dry conditions air volumes change.

In order to know the correct amount of fuel to pump, the engine must know how much air is coming in. That precision involves 14.7 parts air for every 1 part fuel or 14.7:1. In order to achieve their maximum output, they need precise input. Today’s sophisticated computer controlled fuel injected engines squeeze a significant amount of horse power out of each combustion chamber.
