| What is the "special policy" on LB7 injectors?
I have recently developed a smoking problem on my '02 Silverado. Not during acceleration but idling after a short or long run time, I get billows of gray to blue smoke. No loss of any oil or anti freeze. No warning lights. Changed my standard Delco air filter, no change.
Taking off from a stop, with smoke coming out, it clears up in 50 ft or so and no more smoke until I get back to idle.
No smoke on start up.
Any ideas? |
