Clean your injectors!!!!!!!
Ok well first of all I am not talking about just those fuel additives. Those are good for routing maintenance, but every 30K miles or so you should really get a complete professional injectors service. Go to a place that has a motorvac system or equivalent. Your injector spray pattern will improve greatly. Every 90K miles or so you should probably get a complete cleaning and balancing. For this you have to take the injectors off and get them balanced to each other. I have 200K miles on my car now and have always just added the injector cleaners(one of the best I found was seafoam). Because of my regular maintenance, my car has been running pretty good, but it is much better now. I recently went with a complete cleaning and balancing of the injectors and boy does it make a difference. Idles like when it was new, and the acceleration is much smoother. Don’t expect to gain any hp out of this service, but you will get back the hp you lost through time, wear, and contamination build up(you’ll feel it in the acceleration).
If you are experiencing rough idle, bad gas mileage, rough acceleration, and have not been keeping your fuel system up to par(or have a lot of miles), maybe it’s time to look at servicing your injectors.
What I would suggest is:
15,000 mile intervals - seafoam(or equivilant although not many products out there surprise me like this one)
30,000 mile intervals - professional motorvac style service
90,000 mile intervals - complete cleaning and balancing

RE: Clean your injectors!!!!!!!
Not only do you have to make them food, but you have to spoon feed them too?
Google is your friend. Here is just one result, but if you do a search you can get many others
http://www.crfueltech.com/service/sun.html
In short you take the car into a shop that offers this type of service. They tap into the fuel rails and feed a very highly concentrated fuel injector cleaner(much stronger than the fuel additives). The service pretty much removes the carbon build up that effects fuel injector spray pattern and delivery.
The advantage of removing them and sending them out is a calibration of your system. In other words they make sure each injector’s flow is closely matched to the rest as well as removing the contaminants while they are off your engine so they don’t go through the combustion chamber and exhaust.

RE: Clean your injectors!!!!!!!
hmm, ya that seems like it may be a good idea for me to do, my car has been idoling all over the place lately, from like 200rpms to 1300rpms randomly. i have about 165k miles on it as well. how much does this kinda thing cost to get done? is it safe? what kind of shop might have the right stuff to do this?
thanks.
thanks.

From 200-1300, wow. That doesn’t sound like an injector thing. You may want to look for a more obvious problem like IACV, or possibly vacuum leak. I don’t doubt you need an injector service with those miles, but I don’t think that will fix your idle problem. I am not too sure how much an injector service would cost, but I assume it would be less than the cleaning and balance I got. I ended up paying 96 bucks(24 each injector) from RC injectors. I have seen this type of cleaning and balancing for as little as 70, but I went with RC because they were local and have a good reputation when it comes to injectors. You might want to shop around if you want to just get the cleaning service while on the vehicle. About the safety issue, I wouldn’t worry too much, but I would also advise not to get it done to frequent. Since they inject the highly concentrated solution directly to the fuel rail, it doesn’t pass through all the other sensitive seals. However it does go through the fuel rail to injector seal. (Some of the injectors cleaner solutions are hard on rubber seals)

RE: Clean your injectors!!!!!!!
alright cool. i think the idol problem is because of my exhaust set up. i think i need to tighten some stuff up and maybe get a new header gasket. but i'm kinda of interested in this injector service and all because i want to keep my car in tip top shape and have it last as long as possible. ill try and do some more research. thanks for bringing this up, its good information.
