Ok, so within a day of installing my CAI/tune, my power steering went out while I was driving. I kept driving and at every stop light, I would turn off my engine, take out the key, wait, restart, etc., to try to get the power steering re-enabled... nothing happened. After about 5 miles / 15 minutes of driving, the power steering magically kicked back in.. it's been fine for the last several days since then. Has this happened to anyone?

Also, around 5-6k RPM, when at WOT, I hear a noise that sounds sort of like crinkling aluminum foil.. sort of a tinkley sound. Maybe it sounds sort of like a ball of foil stuck in a metal fan, which is bouncing all over the fan because of the spinning fan. Interesting... cause I hear the EXACT SAME sound in my 5-cyl non-turbo Volvo S70 around the same RPM range at WOT. Is this detonation/pinging/knocking? What does that sound like?

 

I lost my power steering after a longtube install but that's it.

 

That sounds like you are describing detonation (or pinging). Make sure you have a full tank of 93 octane (or whatever tune you are using). Until then you can back off the timing by a degree or two on the X-Cal. If a full tank of the proper fuel doesn't cure it, contact your tuner.

 

yeah that sound, if started after your tune, most likely detonation.


The power steering issue was most likely unrelated, maybe air trapped in the pump or some such nonsense.
