77 911: throttle stuck open, linkage operates as intended
Prologue: i have searched quite a bit and found lots on sticking throttle, but all of those have to do with the actual pedal cluster/box and such malfunctioning. This is a rebuilt pedal cluster that still operates as intended. Thanks.
Hi all, i just got home after having my 77 911 inspected (PASSED!!!). I went to take it out for a ride and, im told "due to a leaky injector", i sometimes need to depress the throttle to the floor to get it fired up when warm. This seemed to work fine the last few times i took it out. But now that it was road-ready, of course it isnt working.
I pressed the accelerator down and it didnt fire immediately, so i pushed a little harder. I heard/felt a "click" in the throttle pedal as if i had pushed PAST something. The pedal seemed to return fine though and i have confirmed that the linkage at the throttlebody is operating and returning as well.
Now that it was cold, i went back out, hit the key and it fired up as it usually does, without any throttle input... except it went o the moon! I turned it off well before reaching the limiter. I thought maybe it was extra gas in line from messing with the pedla, but it has now done this about 5 times over the course of 24 hours.
The car has a newly rebuilt 1980 3.0, high compression, small port, with CIS and M1 cams. Could it be that its something in the CIS that i "pushed through" due to maybe a misaligned or poorly adjusted component in the linkage?
Any insight is helpful.
