Three things you should check using a good code checker which can read sensor outputs - the throttle position sensor (TPS), the mass air flow sensor (MAF) and the EGR valve. While you are at it, replace the PCV valve.

Hello I have a 1995 Sonoma 4.3 with 150.000 on her and she ran great tell last week went to pick up a lite trailer and dove it home no problem drove it all day after that. The parked it running fine and next morning it won't hold a idle but clears up at 3000 RPM runs fine drop in gear and it won't stay running??? Cleaned TBI and there was a new fuel pump and filter put on it less them 7.000 miles ago. Found vacuum leak on the booster to manifold fix that still runs like it is misfiring??? Any help would be great thanks no check engine light on.

Hope help with this (remember rated and comment this).

as time goes on yes so the idle speed control is wearing out

check the play in the distributor,and check that the fuel pressure is normal

Did you change the fuel filter? also did you clean the inside of the MAF sensor w/ MAF spray cleaner?

Check to see if it is firing, coil,spark plugs.....
