chooch Member 256 Member For: 20y 10m 23d Location: Adelaide Posted 03/02/08 06:21 AM Share Posted 03/02/08 06:21 AM (edited) A few months ago I bought my first CAPA box and had it installed plus got a custom tune (98 RON). After I left the workshop it was perfect, 241rwkw. After a couple of weeks I noticed the car started to ping at high revs. I took it back to the tuners and discovered that the valve springs were the cause. I didnt really want to spend more dollars to install new valve springs so I decided to just leave the car stock and give the box to a friend.I noticed today that my car has started to slightly ping again at high revs. My car is stock.Do you think the valve springs are now just really warn out?Something I should also mention, my car stock on the tuners dyno was 215rwkw.

Mine used to ping in hot weather, but it was modified. Link to comment Share on other sites More sharing options...

chooch Member 256 Member For: 20y 10m 23d Location: Adelaide Posted 03/02/08 02:00 PM Author Share Posted 03/02/08 02:00 PM Yeah I got the tune done at KPM. It was all good for a few weeks then it started pinging. KPM spent two days trying to figure it out. They claim it was the valve springs.Anyway I flashed the car back to standard and it was all good for a few months but today it started pinging again...........with no tune! stock as a rock.It's not under warranty anymore. Should I go to Ford to get them to check it out? I know it will cost me. Link to comment Share on other sites More sharing options...
