When I get my new tps in the morning, I am going to install it, calibrate it, disconnect it, and map out a crude table of values.
I've been running lean in the lowend (maybe not so low) and super rich up top, I don't know what the valuse are supposed to be, my readings were jumpy, but I think off the scale... heh.. jees.
When I measured the bad switch, it stayed in idle too long (smooth transition though?) and didn't work at all until what looks like half open.
I am amazed it hadn't showed the normal signs before now, it's completely screwed. This kind of background trouble can cost you $$$.
This mesage has been brought to you by the Throttle Switch Association of America, finding little things for you to mull over while you can't sleep thinking about all that rust that hasn't been born yet.
