0172, 0175 codes -leaky injectors?
 

2000 Intrepid, 78k miles, engine light goes on for a while, then off for a while and gives 0172 and 0175 codes. Engine runs smoothly 95% of the time. When the car has been sitting for a while (6+ hours), but in hot weather, it may idle roughly for a minute or two. The mechanic says this is due to leaky or worn injectors and that the computer is trying to lean it up.He says the O2 sensors are within specs. Has anyone heard of leaky injector problems like this? Is there something else that I should look for or try first?

Well, for want of any responses or other ideas, I ran a couple of bottles of injector cleaner through the tank and the problem seems to have gone away.
