need help with my 87 k5
 
hi i have a 87 k5 blazer with a 350tbi when i am giving it gas it runs great but when i let off the gas and coast or stop it spits and spatters like it wants to stall and sometimes it does but when i give it gas it comes out of it. ive replaced the map sensor, tps, coolent sensor, fuel filter, pulgs and wires and cleaned my injectors the check engine light isnt on so i cant get a code im hoping some one can help me get my beast back to full health

Clean the throttle body completely, paying particular attention to the IAC valve (idle air control). Also, remove the EGR valve and clean it. If either of these valves are dirty/stuck, it can cause the condition you are experiencing.
