Question about 1991 Chevrolet K1500
I thought the probelm was the EGR valve. Replaced it ( looked horrible all pluged up) This f ixed Idel probelm temporarily. Now when it is worse then ever. Low RPM's it dose not do bad but anything over 1500 it will Sputter and allmost stall out wile driving until you reach over 3800 RPMs. When engine is warmed up it seems to help a bit. Looking for help please? Mass Airflow sensor? or maybe Map sensor? let me know thanks Anthony
My truck did the same thing a while back and i repleced about everything only to find out that it was the oxygen sensor. This is a very easy fix and fairly cheep. Hope this helps.
