You can to a point. Generally (not always) the coil packs will blister. One of mine had a noticeable blister. Lucy for me it was the front drivers side coil....easy to get a good look at.

 

I kinda figured that since my friends z is running fine i would try to swap coil packs with him. Do a test run and see how it goes from there

 

if it ends up being a coilpack, don't be Asian and buy just 1, buy all 6

 

Would have been good to say you were on emanage and TT lol

All the couplers are still tight? You get full boost normal?

 

You have Greddy TT and e-manage? and still running the oem fuel pump?

Also I remember people used to burn their coils with the e-manage.

 

Update...so I got the car to Frank at Hill's, turns out it was the MAF sensor got maxxed out and was putting my car in failsafe mode without throwing a CEL. Easy fix, however since I was up there I decided to do some upgrades including DW 600 injectors, Walboro 300lph fuel pump...oh and Osiris upRev retune. Was there for the dyno on Monday. I'm getting the car back on Thursday and I can't wait.
As everyone probably already knows Frank is a great stand up guy that not only knows his stuff but he knows just as much about his customers and in this day and age, that's priceless.

 

How much did you put down?

 

391 @ 5.5psi

 

LOL they aren't cheap so I guess I have som asian in me. I ended up extracting 2 from a blown VQ (thanks whoever lost their engine and left it as a donor LOL) -- one to replace, one as spare I keep in the trunk
