CK2510 ht engine light code

[SCWOOD]

Not very often but my engine light will flash a code, the engine stumbles a little then smooths out.This is on start up.Looks like 3or4 long then 3or4 short flashes.I hate to take it to the dealer because it only does it maybe once out of 7 or 8 starts.It would be hard to find problem unless they have seen it before. Anybody had this happen before? Thanks!


PS it has 33hrs on it.
