No way that I know of. It'* non-adjustable. You have slop? Is your Throttle bracket bent, or perhaps installed incorrectly?

The linkage to the tranny from the throttle has some adjustability. Usually only helps if the throttle is too tight, though.

I'm not sure if anything is bent or if i would be able to tell but it'* pretty loose at the throttle body. I could always use knarps for a bike cable to shorten it but i'd definatly feel uneasy about that.

All of them have a little slop there. Including mine. Is it loose in a 'performance feel' sense?

How loose is it? My grand am had a similar problem. Mine was loose to the point however that the pedal would touch the floor, without the TB being completely open. I used some metal pieces on the pedal side to tighten it up. It was a bit ghetto but livable.

The slack that'* there is normal. You don't want the throttle plate opening right away. As long as the plate is fully open with the pedal on the floor, you're fine. The TPS controls the fuel delivered, anyway.

Well i was driving a new impala the other day (those have 3800 II'* right) and there was absolutly no play at all. it felt so much better. Maybe it'* b/c of the 4t65 tranny?
The two cables that go up to the tb are pretty loose though, like i could probably pull them across eachother and put my finger inbetween them if that makes sence.

Need someone with both the Series 1 and the Series II to chime in here. I know both the L27 and L67 in 1993 have the same amount of slop. The difference with the Series II may be that the trans has more electronic controls on the 4T65E trans after 1997.

Don? Gearheads?

Well a new car won't be as worn as a 10 year old one either. If anything a 4t-65 tranny would feel sloppier since they constantly re-adjust.
