dead in stop

[nalgman]

hello guys.

i have this problem.

i ran my blazer 1990 2wd 4.3 z and runs great

the engine is a rebuilt, and these are new components cap,rotor,sparks,wires,filter of gas and air,timing correct,map ,iac cleaned, so the problem is when i run my blazer runs with no problem, but when i got 25minutes of use and make a long stop like 3minutes stop the car starts to shake a little like it's tryin to die. sometimes it only dies . i tun it on with no problems .

so i never in life ever cleaned the egr. so im thinkin this is the cause.

what do you think??

hello.. ok it's not the egr..
1 hour a go i was drivin my truck and was very very Faster and perfect to me.. all was normal.. but when i get to my house y just pressed the stop pedal for 5 minutes and the problem starts.. and when i move the wheels to the right slowly the power steering was making some noise.. and the voltmeter and the oil pressure go down... but in a second going alive...
so after that each 5 seconds the engine was tryin to die.
i heard that the revolution speed of the engine was lower..

HELP please

thanks Nalgman

ok, hows the alternater doing? how olds the battery? and when was the last time afull tuneup was done? and as to idel speed being lower, either the fan kicked on, or you have something like ac or defrost running and the ac pump started worken

the alternater it's ok, the battery New, last tune up 1 month..
no AC or defrost. maybe it's the idle speed.. i dont know..
this can cause the idle speed been to low??

:S hard to find..

Thanks anyway
