Injector cleaner - dangerous

[leonb]

Hi,

I have a 1999 C280 (V6). After replacing the MAF and cleaning the throttle body (very dirty), I still have slight rough idling. The agents plugged in the Star box, but it don't give any error codes. Initially it gave a error code saying the throttle body can't be programmed (or it looses its programming, or whatever. That is what they told me - I didn't see the code myself). This lead to them cleaning the throttle body, and solved the error code.

I now want to try and clean the injectors by adding a cleaner to the fuel tank.

Are there any, and I mean any, dangers to doing this. Meaning can it damage anything, or loosen up gunk that might stick somewhere else and worsten the problem.

I just paid about $1000 for service/repairs and really cant afford any other hick-ups.

How much of the cleaner can I use, and how often.

Thanks!!

Why not try a few tanks of Premium gasoline that already has some detergents added?

Techron. Follow the directions. And a tank of Chevron premium gas to go with it.

Unless the car has done a lot of sitting or otherwise been abused, I doubt the fuel system is full of gunk. There's always a certain risk -- however small -- but you gotta weigh the benefits against the risk.

As long as you follow directions you should be fine. With cars with severe dirty injectors, I have put in a double-dose of Techron fuel injector cleaner in less than a full tank of fuel. I would then drive the car hard, such as hills or mountains and accelerate agreesively.

Plan to do your injector fuel injector cleaning and then change your oil and filter.

When I worked at MB we used to put Techron in on every service. There are two sizes bottles. I belive one is for up to 13 gallon tanks and one is for up to 20 gallon tanks. Just read the directions, It works great.

I forgot one other thing.

It probably is dangerous if you drink it.

Use top tier gasoline all the time and none of this is necessary.
