Have the exhaust checked, you may have a plugged catalytic converter. Have the fuel pressure checked, especially under a load. Good Luck! -
Answer 2
I had the same thing happen on my 1994 blazer. Turns out there are a lot of deposits in the duct upstream of the egr valve that break off with vibration. So when I get the valve cleared after it sticks, some more crud breaks off and the valve sticks again. The solution I did was to disconnect the valve in the open mode. Car rruns smoothly now. -
