A fuel injector on the vehicle is not serviceable, replace it with a new one.
Yes, replace it with a new one.
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
You would be lucky at best if you replace one fuel injector and it didn't cause a miss on another cylinder, best advice- while you have the fuel rail off, go ahead and change all 6 and save yourself trouble in the end.
Not just one. It will still start but will miss.
Fuel injector cleaner is a liquid which one puts in their gas tank to clean the engine and improve fuel performance. Fuel injector cleaner can be purchased at Canadian Tire, Walmart, and at many gas stations.
It has a multi-point fuel injection system with one injector on each cylinder.
I assume you are asking about professional cleaning. Unless you have an injector that is giving you a problem the answer is no. Modern gasolines contain a cleaner to help keep injectors clean. Replace the fuel filter every 36,000 miles. Once a year pour one can of a good fuel injector cleaner in a full tank of fuel. A cleaner such as Seafoam, Techron, or similar product is just good insurance. Avoid the cheap cleaners that you buy for under $2 as they are for the most part worthless.
No, you just replace it with a new one.
there should be 4 little plugs just at back of engine each one of them is an injector
the number 1 fuel injector is at the front of the engine towards the fire wall
Yes, This sounds exactly like what my 97 geo metro was doing. I replaced the fuel filter(thinking that was the problem, obviously it wasn't). Then I finally took it to someone who knew what they were doing and told me it was the fuel injector. I changed that and I haven't had a problem since. Sounds to me like it is definitely the fuel injector. check the fuel pressure controller and the idle control valve, if one is messed up better to replace both as they go hand in hand.
