:cool:
I got to looking at the FI setup on my 01 Lantra w/78000 miles and figured out a cheap and easy way to clean the fuel injectors just like at the shops where they charge $$$$.
Most of the professional cleaners like BG, 3M, and others can use a system where you disconnect the fuel pump, adapt to the fuel rail, and then run the car off of the cleaner.
I refuse to pay the labor (too high) or to buy the tool myself (again, too high)
On the 01, the fuel rail is terminated with a pulse dampener. If this is removed, it is a 3/8's threaded opening.
I bought a 12" length of 1 inch pipe, along with reducing adapters at the hardware store. If they had 1 1/2 inch reducer I would have gone with them as the pipe would not hold the whole can of the BG cleaner.
On the bottom end of the pipe I used a 1/2 inch union and fitted a 1/2 inch water pipe flex hose. This then attached to a 3/8's reducer that could screw into the fuel rail.
On the other end, I used a reducer to get down to the size of an air chuck fitting.
All hardware was about $15.
Our fuel pressure runs at about 49-49.5 psi. I didn't have a regulator for my shop compressor so I filled a portible tank I had with 50 psi.
I pulled the fuel pump fuse so no gas was furnished.
I filled the pipe/tool with the cleaner and attached the air source.
I started the car and let it run until the cleaner was used up.
The car runs smoother, has better throttle response, and is getting better gas mileage.
I used the BG 3 part cleaner that has a spray for the throttle body, the cleaner for the injectors, and a cleaner for the gas tank.
I will try to get pictures to post. In the meanwhile if you have any questions let me know.
Tnx Fred
