Others claim to have experienced idling problems with their GTO's aswell before their its' engine computer learned the new flow of the LS1Speed intake. Initially, the car had a bit of a hesitation to startup when the key was turned, but that issue went away as the computer learned. Probably the most noticeable effect the system had was that it made the intake snarl much more audible, which is always a plus.

The 1966 GTO only came with the 389 cid motor. You could, however, get it with the standard 4 bbl quadrajet Rochester carb or the optional tripower (3x2 carbs).

In my 2004 Pontiac GTO, I had that problem. I took it to the dealer and they cleaned out the ignition with some lock cleaner that you can purchase at home depot and they also cleaned the key .

Yes, but the 1968-1972 rears are 1" wider than the 1964-1967 rears. This may cause tire to fender interference problems.

6.5 liter 389 4bbl puts out 335 hprsepower at the crank. The tri power puts out 360 horsepower at the crank.

There is no idler pulley on this year Fiero so you must mean Idle Speed.

It is most likely that if the idle is high and it wont slow down automatically, 1500 or so, that you have a cracked EGR pipe between the intake and the EGR valve.

There are replacements available on line from companies like "The Fiero Store"

No

In it's original production run, the last GTO was made in 1974. However, it was hardly a GTO, it was more of a glorified Nova than anything else.

Options will change the base figures but Hardtop was 3,753 and convertible weighed in at 3,802.
