I never heard there is a cleaner for spark plugs. If your car's spark plugs are worn, you should change them. They aren't that expensive, just buy them when CT goes onsale.

I am using NGK, which is recommended for most Japanese cars.

There are 3 cleaners I will use for my car:

1. Fuel injector cleaner like 一箭穿心 said. It can clean the deposit of fuel injectors and provide a better burn. However, if you regularly using a good gasoline like Chevron, then you probably won't need it.

2. Carbon deposit cleaner for engine interior. There is a brand called Kleen from GM (I think, I need to check my purcahse receipt), which require a little procedure to use. I share my experiences before, so you may want to do a search.

3. TB (throttle body cleaner). Normally, once a year (maybe longer if I am lazy...), I will clean the throttle body. It does help a lot on my car's idle and smoothness of acceleration.

First, why do you think you need to use fuel injector cleaner?

I will recommend 2 brands: Chevron Techron and Redline SI-1

谢谢sunmax和一箭穿心。是这样的，我的车前一段时间起步和爬坡的时候很抖，提不了速。后来换了4个NGK的spark plug 问题就解决了。当时师傅说spark plug积炭比较严重。开了两三个星期后似乎又有一点迹象，所以我想先清洁一下。

You are welcome.

First a few questions:

1. Besides the spark plugs, did you change anything else? Air filter? Fuel filter? If not, when is the last time you change those?

2. When is the last time you did a tune up?

除了spark plug，没有换其它的东西。上一次换spark plug 是两年半前。tune up 是一年前
