2.3 Galaxy Mis Fire

[alex c]

Hi Fellas,

I am new on here so please be gentle. I will give you as much detail as i can about my problem and hopefully someone may be able to point me in the right direction. Here Goes

 

I bought an 02 2.3 petrol manual galaxy with 60k on the clock a couple of weeks ago for the mrs to run the kids round. All seemed ok but as i drove it for the first few days i noticed that every now and then it would mis fire for a split second so it felt like you had gone over a speed bump. I took it to a trusted local garage and he ran a diagnostic check and there were no faults but as it hadnt been serviced for a while he also changed the plugs ,leads and fuel filter.

 

I handed the car over to the wife last week and all seemed well. However a phone call from her today and its happening again. Seems to be happening when engine is accelerating or under load.

 

Does anyone have any idea what might be wrong? Its going back to the garage on Friday for a proper service but i would rather he changed absolutely anything which could be at fault to save it breaking down with the wife an kids aboard.

 

I work away all week and if it did break down the Mrs would most likely have it towed to the nearest Ford dealer and part ex it for a brand new one !!

 

Please help !!

 

Cheers

Lots of things can cause misfires, but failure of the coil packs is quite common on the 2.3i.

 

Welcome to the forum, by the way! :)

Thanks for the welcome Paul.

From what i saw the mechanic changed the plugs and leads. I think he also changed the coil pack but it was a single black box at the end of the engine that all the ht leads went to. Does that make sense?

I sold the wifes X trail and replaced it with this in a cost cutting drive. It may spectacularly back fire on me yet !!

 

Cheers

The later 2.3 like yours has a single coil pack mounted on the outside of the head as you describe, the earlier ones had two on top of the head and less plug leads i believe. I run the same car as you and have had to change my leads twice now to get rid of a bloody misfire. I am NOT saying this is your problem but don't buy cheap leads like i did it don't pay. I am now using MAGNECOR, expensive but cured mine. A simple check that may help is to remove the top engine cover approx 8 x 10mm bolts to expose your plugs and leads then once dark and i mean dark ie no street lights have the wife start and rev the car while you look closely for arcing of the leads especially under this cover as this is where mine were touching the head on both occasions due the lack of room. As mentioned it could be anything but this don't cost nothing. Best of luck. :)
