Engine Performance problem
1986 Ford Bronco V8 Four Wheel Drive Automatic 200000 miles
My Bronco has no power at low RPMs in drive or reverse. Out of gear it idles fine and revs with no heasitation. In drive or reverse it feels like I am starting in a high gear if it was a manual transmition, or like it is cold and the choke is stuck if it had a carb or as if it is missing, when I get over 1500 RPMs it seems to run ok.. I have changed all fluids and filters, plugs wires and cap and roter. We checked the timiing, compression is between 140 & 150 on all cylinders, fuel pressure is at 35 at idle and increased to 45 as the RPMs increased. When we put a vaccume on the EGR it stalled the engine at 10 psi. My code readre gave a code 11 engine off. But the continous codes are 31, 53, 63 and engine running are 34 and 44. Can you help me figure out what needs to be replaced or cleaned?
have the same problem?
