PCV is at the back on the lower intake.
You can clean the throttle body and the IAC valve.

Find where your car likes its base timing the best and leave it there.

Hope this picture helps, this shows the back of the lower intake, in the middle. The hole there is where the PCV goes.

For a tune, since youre in Michigan, you could check out Alternative Performance.

Few guys that can help over the internet (that are good with the 94-95 computers) are, in no particular order:

Besides your typical bolt ons, you're then getting into heads/cam/intake packages or power adders.

what about the IAC what is it and where is it. as far as tune if i do anything ill use lidio just dont know if there is much to be had on that car i know the new ones it can be significant. if i rememember right back in the day when these cars were new the fast guys just advanced the base timing to around 14 degrees i dont recall anybody putting chips in their cars. kid loves this thing cruising around the small towns where we live pipeing everything in sight

IAC (Idle Air Control)on a 94-95 5.0L
a. is 8mm bolts
b. the actual IAC
c. connector for the IAC.

At its current state a chip (not one of those bullshit hypertech one either) is probably not worth it. Some gains can be had though even with an "email tune". Cheapest Ive seen and used personally is about $199 using a moates chip, however my car is not stock.

take the IAC off and clean it or replace it. kids birthday is next sat you talked me into the pro kit and str,s what do u think about a throttle body i hear that car has a 70mm intake opening so you gotta think a 70mm body wouldnt hurt ive heard different things about the stock body size looks like its 65mm

I would clean it with a throttle body & air intake cleaner and put it back on, if it looks gunked up.

Stock throttle body size was actually 60mm, on both the GT and Cobra. A 70mm throttle body will help gain some power. Buy a good brand, dont buy Professional Products throttle bodies or any offshore made one.

SR is a "house brand" for American Muscle, as is SVE for Latemodel Resto.

BBK or Edelbrock seem to be the viable choices.
