My 93 saff has developed a problem. I noticed the other day that my tps reading on my secs was sticking at around 5% when the throttle was fully released and the tickover had raised to around 1000 rpm when warm. So I thought maybe the tps just wanted some small adjustment, so I've moved it and could only get it to drop as low as 2-3%. So I left it at that. But now when I started it the car idles at around 1400rpm. I tried moving the tps but it's staying the same. If I unplug the iscv when it's running it drops down to about 850rpm. And the other thing I've noticed is that the Amal valve clicks when you open the throttle slightly and clicks again when you release??? Wtf???
