Question about 1989 Chevrolet K1500
I have changed the EGR valve and change the spark plugs and the master computer, could it be the throddle bodies. I also changed the pvc valve, and the temp sensor. the o2 sensor is still new.
Most likely cause would be a vacuum leak somewhere. spray some carb cleaner around intake WHILE ENGINE IS COOL!!! and see if you notice a rpm change
