Hi,
Here are 2 products which I have used successfully. The 1st is BG44K -

BG44K is used by many professional shops and is probably the better of the two, but I have also used the Jectron and found it gave good results at ¼ the cost of the BG44K.
If you have never cleaned your injectors, I'd go with the BG44K and then use the Jectron annually after that. Hope this helps...
Happy Motoring!... Jim'99
