So, two weeks after finally, with the indispensable assistance of Montreal's own blacknblue, applying the TH fix to my car, I have a problem.
Car was great until Friday afternoon, after a long, high-speed run down the highway. (85 MPH for a hundred or so miles)
At the first pee break, the car idles down to about 1500, then jumps to 2000 or so, sticks there for maybe four or five seconds, then settles in at 14 or 1500 RPMs. Has been that way ever since...won't idle below about 1400.
Until just now, when I removed the TH plug, and everything's back to "normal", throttle hang, but a nice 750RPM at idle.
Any ideas?
