P38 Ignition Coil Hell

hoarec · Nov 8, 2009

Can anyone offer some advice? I am trying to replace my ignition coils on my P38 4.6 (Thor Engine) but as the car has been converted to LPG I cannot get the coils and bracket attachment out from behind the engine, dismantled the whole lot before realising I could not get the things out.... (difficult enough to get at anyway....) The only thing that I can think of is to dismantle the coils from the bracket and see if i can get them out individually........Has any one else had this problem?:doh:

OK, Have given in and booked it into a garage.....£70......and bought some Magnecor leads to fit .....gotta be worth paying to get rid of the hassle...

Funny you should mention coils, whats wrong with the old packs?

hoarec · Nov 9, 2009

Only just bought the car, and the parting shot before I left was "The coils will need replacing at the next service", i have bought a set and tried to replace, but could not get them from behind the engine due to LPG pipes, so have now booked it in to a garage..... The engine is starting to run a little rough (not too bad, but enough) and I am replacing the leads as well.....It looks like someone has already tried to remove the coils before as they are only being held on with one bolt.....

If theres nothing wrong with the coil pack why change them?

The coils are starting to break down,

Out of curiousity are you have problems with the running of the engine?

hoarec · Nov 9, 2009

previously it was just the odd miss fire when accelerating hard, now it is noticably running a little rough, but besides that it's fine....

Measure the amount of air flowing into the engine, if you need help with that sumone u'll be along to explain better than me... im a novice anurl

air flow senser easy to cheeck if you want start up get it warm. get somebody to keep revs up a bit and unplug it tis on your right on big pipe to air filter just pulls out

I had the thor 4.0 with motronics ecu and it would appear that they are much more adaptive and sensitve...hurrah for pickier technology.
