I recently installed PI camshafts in my 96 GT and
my car would idle horrible and drive like it was running
on two spark plugs.I checked everything under the hood,
all connections,and everything looked right but, my car
was still running bad.Last week I took my car to the Ford
service department because I couldn't find the issue after
the PI camshaft install and I had a check engine light for
some reason.Sure enough my mechanic didn't know he had
to reset the cam timing and that is what caused the check
engine light to come on because my cam timing was incorrect.
My review of this mod is that it changed my exhaust tone
and now my car isn't as loud as it was.Through my POS plastic
non-PI intake manifold I probably only gained 8-10 rwhp or that
is what it feels like.My car seems alot more active with the PI cams
and seems like it is faster.If I knew this I would have done a PI intake
manifold instead but, all in all doing any mods to the pig is a good mod
so,I am happy.

So...how do u reset your cam timing?? I am going to do this mod on my X-mas break. Did you use the cam changing tool or did you take off the whole front timing cover?

Yeah what do you mean by resetting the timing?? It should just be a drop and go swap, at least thats what it was for us. Although we didn't skip a tooth on the crank gear like it sounds like the person that did the swap for you did...
WHTY98 if you want I have a link in my sig for how we did the install, several pics linked too.

That is what you would think but,he didn't skip a tooth.
If he did skip a tooth my car probably wouldn't even drive.
The Ford tech inspected his job and diagnosed my car and found
that the cam timing was somehow incorrect so,
he reset the cam timing.I have no idea how he did it but,
it took the Ford tech less than one hours labor to fix the issue
I'm happy.I thought the timing cover and valve covers were
going to come off to fix my mechanics error but,fortunately
that wasn't the case.The PI camshaft swap isn't really worth
the trouble in my opnion but,a mod is a mod on this car.
I have installed numerous staged camshafts on Subaru's before
and never encountered this problem before but,then again I
never skipped a tooth before.

Pennywise, he must not have kept tension on the chains when installing the cams and skipped a tooth, that would cause the problems you were having. That must be what the mechanic means by "resetting the timing." But the good thing is it was a quick fix and you didnt have to spend all your time trying to troubleshoot

I'll bet you he installed the cam sensor on the driver's side timing cover.

Why didn't you do the intake at the same time? Its almost useless to not do them together....
