Title: Help! Engine code 1271 says 'Ignition Coil 1' has an issue (?)
Post by: adam12hicks on June 20, 2008, 10:28:11 AM

This was found during a stomp test.  I don't notice any missing or hesitation, but I'd like to check the contacts and test a known good coil.

My problem is I'm not sure how to tell which coil is 1, 2, 3 and 4?  Does anyone have a quick diagram that shows which coil is which?

Thanks!!!

There should be numbers stamped into the plastic that surrounds the coils.

Wouldn't plug number 1 be connected to coil number 1?

Now stamped numbers are handy :)  Sorry I'm sure plug 1 goes to coil 1, but to be honest (and I'm not afraid to admit it) I don't know if the cylinders are 1-4 front to back or back to front, so I wanted to check to be sure before making any assumptions.  I can do a lot of work on these things, but I don't do block work.  I pay someone for that...

Thanks!

I believe the cylinder numbers go front to back.
