Alright peeps well i bought this pilot last week and took it to the shop this morning due to my check engine light turning on the same day i bought it... so the shop called me this morning and told me two of my coils were gone along with plugs ofcourse and my egr valve needed to be replaced ....sooo does anyone know if this is difficult to replace since ive never messed with coils before (is there a certain way to do it ) also where is the egr valve located on the pilot(J35A4) ???any help would be appreciated this way ill save me 600 Dollars in labor costs lol

depending on which coils need to be replaced you might have to pull the intake manifold. I would start by replacing the egr valve and clearing the codes, then see if the misfire dtc returns

remove the 4 10mm bolts securing your plastic engine cover and your egr valve will be just to the right of the front head, very easy to replace 2 12mm bolts and 1 connector.

Like i said start by replacing the egr valve and go from there, as ive never seen 2 coils go bad without creating some major driveability problems.

 

I own a 2004 Pilot and have replaced spark plugs before.

If you are referring to the coils above each spark plug, those are easy to remove. The only thing you have to remove to get to those is the plastic engine cover. Once the cover comes off, you disconnect the plugs from each coil, then remove each coil with a hex bit. The front coil bank is easy to get to. The rear coil bank are also easy to get to, but hard to see. You may need a step stool to see the backside of the motor.

 

Clear the codes, drive until they come back, tell the shop you need a printout or all the FREEZE FRAME data that goes the the DTC, post the info here and we will try to let you know what to do next.

If you are getting for example a P0302 and a P0304 for #2 & #4 misfire, then just swap those coils with the other two and see if the problem follows the bad coils or stays with the bad cylinders / spark plugs / injectors. This of course will require clearing the codes after the swap and more OBDII drive cycles to reset codes again.
