After I recently replaced the spark plugs I began to get intermittent "too lean" codes. My long-term fuel trims are usually in the double digits. I took the car to an independent mechanic And he showed me that the leak was near the fuel injectors using his ultrasonic tool. It looks like the intercoolers have to come off to get to the fuel injector seals. Too bad I didn't know this earlier when I replaced under the supercharger hose and a bunch of other stuff.

Since I'll be in there again. Anything else I should look at? Perhaps have the injectors tested or cleaned? For the past few weeks I've not gotten any codes but long-term feel trims are still over double digit. Car has 97,000 miles.

 

Were the seals disturbed when you changed the hose under the SC?

The reason I ask is we don't see that problem ever. Might be something as simple as reseating the injectors and that is easy to do.

You can have the injectors cleaned and balanced but I have 110K on my 2005 STR and never touched the injectors so I don't know that they need anything?
