V6 - Which Lht Eads Where

[geoffandjen]

Hi,

 

In trying to resolve my misfire, I had a thought. Without a manual, I do not know which leads go from which sockets on the coil pack. Now, you would normally expect that nothing has changed. However, I did have a garage replace my drive belt recently and it is since then that the misfire occurs. I assumed that if two leads were 'swapped' in error, then the engine would misfire extremely badly, and possibly cause great damage - am I correct?

 

But for my piece of mind, can somebody tell me which leads go where. I notice that the channels and leads are numbered, but I cannot see the coil pack markings if there are any.

 

Three at the back of the engine compartment, drivers, middle and nearside, three at the front. Connecting to coil pack, top 3 and bottom 3.

 

Thank you in anticipation.

Hi,

 

Sorry to bounce this, but still need help with which HT Lead goes to which port on the coil pack. Can any of you V6 2.8 1997 owners help?

 

Thank you in anticipation.

Since there is only one 'drive belt' on a VR6 I cannot imagine that the HT leads would be disturbed by changing it since it is at the opposite end of the engine to the coil pack. It's a coincidence.

 

Yours is a 1997 car and will likely be on about its fifth set of leads so is about due the next set now.

 

Unless you've changed the plugs and leads recently I strongly suggest you do the lot before your coil pack gets damaged, the engine itself will be fine.
