Calling C3 owners with TPI
All,
I have a 71 with a TPI setup from a 90. My question has to do with the accelerator cable linkage to the TPI.
I'm using the OE throttle body rotating cam from the 90, a sheathed cable and the accelerator pedal from the old 71. The problem is that when the acc pedal is fully depressed, the throttle body blades only open about 40%.
Has anyone else had this issue and, if so, how how you fixed it?

I know this is not much help, but when going to junkyards, I found the basic mechanical stuff to be fairly simple to line up, just take a length with a steel tape measure, look at the cable ends, and mounts...
and figger on doing what I did for my '72, taking that hole in the firewall, and making it square, and shoving the junkyard cable into it, the end did fit on the gas pedal just fine.....
Wish I could remember which car it came from, but it was a smallish GM car....nothing exotic....but this cable been there some 15 years now...
so get to work, pick a nice day and enjoy the sunshine....
:cheer s:

I had a similar problem using the earlier throttle body, but mine was opening about 75%. I was able to bend the attachment at the pedal end of the cable and get the other 25% (I can't even remember what the fitting looked like, but I remember it being pretty obvious what needed to be bent)
If I remember correctly, I used the throttle cable from a Trans Am (on the recommendation of someone else who had done the conversion), and it fits pretty well, though I wish it was about 4" shorter.
Good luck.
