2000 Ford Focus SE, 4 cyl - A few weeks ago engine light came on. Check the codes, it was for a mis-fire on 2nd cylinder. Found that the plug wire was not fitting correctly. Re-set, but it came coming off. Due to age and not sure of how old plugs or wires were decided to change out. All plugs and wires were replaced with new ones. The old plugs were set at a gap of.045, yet the specs called for.052-.056. New plugs were set to specs. Codes were cleared.
But then began to experience the engine dying every time the vehicle was put into park. No new codes issued. This behavior was not consistent, as the dying occurred at certain runs and then would not occur at all. Has happen with air on, then with air off. Has happen when decreasing speed to a stop light.
Pulled plugs again and reset the gap to the original setting thinking that maybe there was a connection. But the problem still exists and no new codes have been issued.
Wanting to find a direction to fix the problem. Currently at a lost due to the inconsistent behavior.
Sometimes it does not happen at all and will not die, then shut vehicle down and restart it, it will start up but quickly stagger and die. You can force it to maintain by pressing the brake and gas and jump shifting to drive. Then other times it starts up, runs fine never showing a sign of issues.
have the same problem?
