Legacy Bad gas, injectors, cleaners, what now?!!?

I posted a while back in here about some engine noise I was having. I personally thought it was the injectors, and after running some Mobil Super-duper high grade good-ness and some gum-out my 'noise' vanished, and whoa man, did she run right for the first time in a while.

My first tank of gas after the cleaner was 91 from a local Admiral station. towards the end of the tank, I began to hear the noise creeping back again. Today I dropped my usual 89oc in an the noise is beginning to regain its former level.

Obviously, I'm done buying gas at Admiral.. but I fear that a year's worth of their 89 has left my injectors done for. As the mechanic said when I had it looked at..

"maybe you used gas that wasn't as good as advertised"

gee thanks..

Anyways, short of adding cleaner to every tank.. should I replace my injectors? Can I do it myself or do I have to pay capt' obvious to do it for me? Where should I get the injectors? Any suggestions on aftermarkets that might work a little better than stocks?!!?

Arghh....

stupid gas...

Also what gas do you guys recommend?

I'm going to try to help you out here.
1) If you trust your mechanic and he told you they were shot, then they are. As far as performance ones, I found these which I've heard were pretty good. Check them out CLICK ME

2) If you know what you are doing around an engine then do it yourself, if not then don't. Pick up a repair manual and look it over. If it looks intimidating, don't do it.

3)The whole putting richer gas thing in your engine, I've seen debates on this. Some people say yes, others say look in your car's manual and put in what it says to put in.

Sorry man, I wish I could help out more, but at least you can look at the link and ask around about the Bosch injectors, which should fit the EJ25 engine unless I linked it wrong. Good luck man.

How about changing you fuel filter and having your injectors cleaned by r/c or a similar place. Maybe you could buy a used set and swap them while yours are being cleaned. Or just run those and not worry about cleaning the originals.

If one of them fails shut or only opens partially your going to run lean and have the potential for bigger problems.

Good luck

Thanks!!!

The mechanic didn't exactly say "your injectors are shot" he just implied that the noise "might" be from bad gas. Which is what the problem is. I assume, knowing most fix-it places, if they can find something to charge you for, they will.. these guys didn't.
So apparently he didn't think they needed to be replaced, but that they were just dirty. Of course, he didn't offer much more in the way of 'what next'.

I'll probably start with a new fuel filter since it's got 56k on it (sorry I was jobless and broke for a while and the ole' suby is in dire need of attention, obviously )
I think with a new filter, and different gas, I can get more life out of these injectors.

Again, thanks everyone for your help and input.
