Where are my fuel injectors?

Question

I've got a 1998 S reg mark 4 VW Golf 1.4 petrol. I've been told I need to remove my fuel injectors and give them a clean. The problem is I have no idea what they look like or where they are under the bonnet. How do I get to them? What do they look like? Are they simple to remove? How should I clean them?
Please help!

Answer 1

They are attached to your intake manifold...to get to them you open the hood and will then have to find the fuel rail(aluminum strip about 7-10 inches long and 1-2 inches wide). To remove them you have to remove the fuel rail and then they simply pull out. On some cars though you will be required to remove: engine shields, air intakes, throttle bodies, hoses, vacuum hose....so unless your really good its best to take this in and have it done. If you decide to go forward its best to find a parts store and buy a basic repair manual as they will give you step by step instructions on how to do it specifically for your car.

And just calm and fears this sort of thing is exactly the same in american cars as in cars in Europe.

Hi there,
Can I suggest that given your explanation, can I assume that engines are not part of your daily routine.
If you visit a good veh spares shop/motor factors, That you buy a fuel system cleaner. The fuel system cleaner is added to your fuel tank and mixed with petrol in your fuel tank. It's best to add the fuel additive to an almost empty tank when you visit the fuel station and then add fresh fuel, more than half a tank is advisable. The additive is mixed with the fuel in your tank and when you use the car, it will clean the relevant parts of the fuel system when you use the car ie valves and injectors to name a few parts.
Just to add quickly, todays fuel has so many additives in the fuel which is designed to help it burn. If you don't use the car often enough the fuel and additives seperate, the additives sink to the bottom of the tank and are drawn through the fuel system and coat componants with a tarnish/gum and the componants can stick and cause eratic idle and bad fuel consumption.
Use the additive and from then on always fill your fuel into an almost empty tank, this ensures that your putting fresh fuel into the almost empty tank with no stale fuel in it (this goes for diesel and petrol)
There may be another fault which could be causing similar conditions.
Sorry it's been a bit long winded, Hope this helps!
Good Luck.
ps Forte fuel system cleaner is the BEST and there is also Wynns fuel system cleaner, 2nd best.
When buying the cleaner ask for advice don't be pushed into buying branded ie Halfords own make, usually cheaper. spend some money!!

Ballpark info: TBI (Throttle body injection) fuel injectors are located in the throttle body, like a carburetor. PFI (Port Fuel Injection) fuel injectors are located in the intake at each cylinder intake port.

Just as a safety precaution, if you don't know what they look like, you shouldn't me messing with them.

Dont touch them mate,go to a car diognostic clinic and they will pump them under pressure to clean them,or get a bottle of redex and pour it in to a half tank of petrol and take it for a good 30min blast to get most of it through your injectors
