Hello,
My 04 lly is starting to throw the check engine light, and drop the throttle limit to 2000 Roms. Nothing consistent triggers it, it just happens every 1 or 2 weeks. Disconnecting and reconnecting the batteries will clear it for week or two, when it runs normal. The trans (both)and fuel filters were replaced around 25000 miles, and the K&N air filter is relatively clean. The truck has a total of about 64000 miles on it. Any ideas?
