Boxstercol Posted August 12, 2016 Report Share Posted August 12, 2016 Going to have a go at changing the coil packs on my 2005 987 over the weekend after OPC advised them at last service due to some cracks being identified. Any hints / tips / do's & don'ts gratefully received! Cheers. Link to comment Share on other sites More sharing options...
marts500 Posted August 13, 2016 Report Share Posted August 13, 2016 Pretty straight foward apart from the 2 cylinders nearest the front of the car either side.A bit awkward.I think when i did mine i had to cable tie 2 hoses away from the area on the N/S.You might as well swap out the plugs while your there and check the coil bolts you are using are the right length as some coils have a thicker baseplate.Also make double sure the multiplugs go back firmly into the new coils when done as if you crack it up on 5 cylinders etc...it will trip the engine light which you will have to clear even if you rectify the problem.

Cheers. All done now & appears to be idling ok so hopefully I haven't made a balls up of it!! Will take it out for a drive later to make sure all is good. You were right about the coils nearest the front - they were definately the more tricky ones to do. I found the drivers one more difficult as there wasn't alot of space to try & retrieve the rubber boot over the electrical connector. 5 out of the 6 coils that came off were cracked or showing signs of cracking, not as bad as some I've seen but glad they've been changed now.

marts500 Posted August 13, 2016 Report Share Posted August 13, 2016 Well done that man....you're right about the o/s connector.I was convinced it had clipped in only to set off the engine light.Thankfully i had the carsoft PORII to reset it...?

cj225 Posted August 13, 2016 Report Share Posted August 13, 2016 You're luckier than I was! I went for a long road blast a few weeks after changing my plugs, and at 70ish suddenly had EML on, car was shaking like a good one, spluttering badly... I drove home planning whether or not to break it, how much things were worth etc... One of the coil pack connectors had come off Link to comment Share on other sites More sharing options...
