05 freestar hesitating
our 05 freestar started to hesitate (sputter) when climbing a hill about a year ago but no engine light came on. now the van seems to do it at take off and sputtering at idle but when it finally comes to highway speed it runs fine. my wife (she drives it) says she puts it into neutral at stops now, otherwise it seems like its gonna stall.
the engine light came on (engine light comes and goes) and the code said a missfire on "x" cylinder so i changed the plug on this cylinder only, but a few days later same story. the problem seems like it started to happen when there's a load on the engine, i.e. climbing a hill, accelerating, but its getting worse!! wondering what to replace next? feels like its spark related to me but why would it run ok when driving on a level highway at say 100kms hour. the van got approx. 230000 kms on it. 4.2 liter any suggestions would be appreciated.

Re: 05 freestar hesitating
When was the last time you had all the spark plugs, wires, and fuel filter changed?( A Tune Up) I would do that 1st if its been a while.

Check your maintenance records to see if your on schedule.
Doing regular maintenance can weed out and prevent problems. 1) Replace Air/fuel filters. 2) Clean MAF sensor. 3) Clean throttle body. 4) Have a back pressure test done on your catalytic converters. 5) Tune-up - plugs, and wires. Do one step at a time until your problem is resolved. |

Re: 05 freestar hesitating
Agree with Catvents. Check the coil pack. I had one go bad. Mine had a slight crack on the bottom. After testing between the low an high voltage plugs I found that it was a bad coil.
