so I pick up this cirrus drove fine first day . Next day in the morning I turned it on . About a minute went by and it shut it self off . Thought maybe it sat awhile before I bought it . So drove it to work and with in 25 minutes came to a light and it shut off at the light .started right up . Still doing the same thing . Replaced the alternator because it failed voltage regulator. Swapped the auto shut off relay . Cleaned the throttle body and cleaned the iac . No change . No codes no lights on dash . Any ideas ?

I know you said you cleaned the IAC, but you may want to test this further. Is the vehicle idling erratically? Is this vehicle equipped with cruise control by chance?
The idle is smooth only when you drive does it get low coming to a stop almost stalling or just stalling outright. In park it’s fine . As for cruise control. I not sure . I drove it for about 4 days . And haven’t explored the options yet . It’s parked till I can figure this issue out .

So I did a test on the tps to really see what’s going on . Showed 5 at rest and 7.7 with the acc on and 8.5 at idle. So Because I seen what I assume is low volts I put a spacer on the throttle cable and brought it up to 90v then when I started the car it went up to 1.02 . And a code came up as high idle. I did notice rough idle but a think that’s because I put a spacer . I removed it and it back to 8.5 . So far that’s what I got . Next is the crank sensor.

These readings are bogus. The TPS voltage is about 0.7 volts at idle, increasing linearly to about 4.0 volts at wide open throttle.
Oops that’s .77 rest . .85 at idle . And when wot it’s 3.75

My money is on the distributor. Since alot of you guys say it’s a huge issue with the stalling . Next to the crank sensor. And the car throws no codes , that’s annoying as hell by the way .
