I have this issue when the car seemingly acts up at a certain temperature before warming up. It works well when I start it cold, but depending on ambient temperature, in a couple of minutes throttle acts weird until the engine warms up further. When this problem occurs, throttle response is strange. At first, when I depress the pedal, the car accelerates; when I press a bit more, nothing happens; when I press even more, I get a surge of power and it accelerates again and at higher revs everything is OK. It happens somewhere between 1000 and 2000 rpm, so when I'm cruising, I can lose a bit of speed and when I adjust, I also get like this jumpy acceleration from nothing to a lot.
The car is also shaking a bit when idling with the engine warm.
The ECU gives me codes 21 and 41.
Just recently I replaced a bunch of vacuum lines but didn't really manage to do all of them.
I tried to check the CHTS but I'm having issues figuring out which connector it is and the leads of my multimeter are too thick to check it on the ECU connector. I got a 5.1 kOhm reading on some terminals I thought could be the CHTS connector but I'm not sure; the engine was warm then. I am going to try again to find a connection to the CHTS I can measure the resistance at.
It's a European 1987 turbo version; it has some small differences from the US ones.
Reading about similar issues have made me suspect the CHTS but could it also be something else? The error codes don't seem to indicate any problems with it.
