Engine Performance problem
1997 Ford Probe 4 cyl Front Wheel Drive Manual 130000 miles
Whwn sitting still the engine runs smoothly, but when you accelerate in skips bad. When you are driving it, each time you shift gears it cuts out. I have changed the plug wires, plugs, fuel filter, air filter & checked the distributor and rotary button. The fuel pump even checks out. Any ideas as to what the problem could be?
