engine dies and backfires when press gas too hard...
I am frustrated! I have a 96' Bonneville and the engine keeps cutting out when I am driving down the road. In higher RMPs it seems to run fine. In lower RMPs is runs O.K. as long as you don't push the gas too hard. When you are running low RMPs and push the gas to accelerate more than 1mph/sec the motor will kill and then backfire. If I am going 55 down the highway and the car is in overdrive and i step on it the motor will die. It can not downshift because the motor doesn't run up the RPMs to drop it a gear. So I have to manually down shift, accelerate, and then put it in OD. I have replaced the sparkplugs, the wires, cleaned the air/gas sensor, and even took out the honeycomb in my convertor to try to fix it. Any ideas? There are no codes and the check engine light is not on!
