How do you clean injectors? Do I need new ones?

With the mods in my signature will I need to get new injectors? If not, how would I go about cleaning them? Do shops usually clean them for a good price? I have bad fuel milage (even stock it was about 11mpg or less) and with these rising prices I want to get to the bottom of this!

You can have injectors cleaned for VERY cheap. Even cheaper would be a bottle of fuel injection cleaner. Try that first before putting your car out of comission.

Just found this the other day. Has anyone had LPE clean their injectors or found some place better/cheaper?

Most people seem to charge $20-25 per injector. The testing/cleaning machine that runs 4 injectors at a time costs ~$1,000 and it does use solvent. So there is a consumable cost of maybe a couple of bucks per set. It takes maybe five minutes per group of four injectors to clean and test them. So the price seems high, but I just don't know of anyone doing it cheaper.

LPE Cleaning

I haven't done it but I sure would consider it. Supposedly they know what they're doing and that seems like a reasonable price to me.
