well here is the newest problem with the sy.

i noticed yesterday when the truck was idiling for 10 min or so, the idle rpm would drop to around 500 and it would be real rough then rise back to about 1000 and the CE light would flash. then when it was time to put it in reverse the motor would stall. after backing up and putting it in drive it stalled about 2 more times. again flashing the CE light when the rpms got real low. it is also sputtering pretty bad on part throttle just driving aroung town. if i am going thru a parking lot or something maybe about every 4 times i touch the gas peddle the motor will rise in rpms to about 1500-2000 then it will just sputter and not accelerate about 3 seconds later it will be fine. I haven't gotten DM on it yet but i know this is going to be harder than a WOT problem. This has been going on for 2 days the first day not as bad but when it thru the CE light it stayed solid, until yesterday. fuel press is good, base of 50 and rises with boost.

i appreciate any input. thanks

Flashing CES light means something is way wrong, the ECM is in 'limp home' mode. Best to read out the codes (better yet, hook up a scan tool and see what's going on) and NOT drive it until you have it sorted out.

no i am not getting flashing CE light. what i am saying is that it didn't stay solid the first day. it would just flash once when the rpm's dropped real low.
It stayed solid the following day then it didn't come on at all the next day.
can we check & clear codes with DM? My friend found a program called Freescan supposedly it will work on the sy/ty. i'll try it out.
