Thanks, really. The very detailed pictures and instructions helped me change all my plugs. I enjoyed the work and the money I saved. I wouldn't have done it without having seen these pictures.
Thanks

Awesome post Sir!

so I unplugged the MAF and the engine kept running, it should have died immediately,

Seriously? I have unplugged my MAF several times with no change to engine performance. I even drove about 1 mile (in a deserted parking lot) with the MAF unplugged. Maybe I need a new MAF as well. Thanks for the tip. Hoping this solves my problem.

okay... no.

I went out an bought a new MAF based on this thread and no dice. I still have a major problem. So, in my case, (failed acceleration, or useless gas pedal), when I unplugged the MAF, it had no effect on my driveability, yet the MAF was fine. Just putting that out there for reference.

Thank You for the great instructions! Thanks to you, I'm mobile again after being "broke down" for 2 days. Take care!

Thank you! Like you said, the car wouldn't idle, 'it would, but rough', but I think the tell tale sign was the shaking steering wheel. At any speed. Except when decelerating. then it cleared up. Hit the gas, shaking wheel. Just that little bit of info was huge for me in diagnosing the problem, My V70 needed a new ignition coil. All I did was replace all spark plugs (Champion Double Platinum Power Premium Plugs), found the one that was wet, And viola! I knew exactly which coil to replace. $18.00 for plugs.$51.99 for coil, and the car runs like new. 118,000 on the wagon, Just acquired her three months ago, hope I didn't make a mistake. Several yellow lights staring at me.

Wonderful tutorial with great pictures. I want to chime in to say, 'Thank you' to E170_Driver and to confirm that these instructions for changing plugs and coils work for the 1999 S70 (non-Turbo) as well.

Wish we had done this sooner. Couldn't believe how easy it was to replace all five coils. (I wasn't taking a chance on just doing one). Car started up this morning without the check engine light on. We couldn't have done it without your help!

All 5 is a-bit of a financial stretch especially if buying OEM. which aftermarket one did you choose if you did? At first symtoms of bad ignition coils I cut the 'skirt' from bottom approx 7mm just right above the 'shoe' so it doesn't touch the plug's chassis. It prolongs life to about 6000mi extra.
