Been a while since I've had to post about my Caddy acting up(thank the car gods), but she is getting moody again. Thanks to the forums I replaced my burnt out starter with ease last week and now she fires right up. But now she is stalling at red lights and today it stalled for the first time while decelerating to a stop. It was doing this prior to me changing out the starter but it has only started doing this maybe 5 thousand miles ago? It does not do it all the time, maybe once or twice a day, and I do almost all stop and go driving. At first it wouldn't throw any codes but today, I got some! And they are...
DTC P1599 Engine Stall or Near Stall Detected
DTC P1520 Transmission Range Switch Circuit
DTC P1350 Ignition Control System
DTC P1375 IC 24X Reference Circuit High Voltage
Another thing I noticed it took it 2-3 cranks before it started back up after stalling while idling in my driveway for about 1-2 minutes, and it was kind of a sluggish fire up and I had no movement of the tac needle until I restarted it.
I have very recently put new plugs(delcos, but I did not get new wires. It had bosche's in when I bought it and they needed to go), cleaned out the TB, EGR, IAC, and checked the vacuum lines.
Have not checked fuel pressure during stall but FPR is dry when I pull off the line. Have not checked fuel filter either.
Voltage stays steady above 14v during stall.
I'm just wondering whats next? Crank sensors? Cam sensors? Coils? Wires?
Thanks in advance.
Hi, I have a 93 Seville SLS. I think this sounds similar to my problem. She was throwing Voltage too high code. some times INFL REST (air bag light) and every once in a while stop for no reason. I figured it must be electrical. Well I over looked the obvious. Does it seem to happen when your gas is low? Turned out to be my fuel pump.(some wires are there too) I got it changed and al the lights and bells stopped but the car doesn't !
Well, the INFL REST light returned. Doesn't stall though. Guess I need to check the electrical after all.
I had just under half a tank in it today when it was doing it. I also had bad/weak fuel pump in my head, but im praying not. I do have a bad habit of running it low before I fill it back up..I also have an airbag code pertaining to the passanger side pre-tensioner. I never would have thought that would be connected to this in any way..?
It seems to be doing it more often the pass couple days. I think I'm going to throw crank sensors in it tomorrow and pray that helps. Should I replace both of them? And what's the easiest way to get to them?

Re: Another stalling Seville.
Always do both. I got both of mine from Amazon for about $77 incl shipping.
There is no easy way. Drop the lower air deflector. Then remove the oil filter adapter. Then the CKP sensors are a bit more accessible, but it's still a tight fit. You'll need a long extension and a universal joint.
There should be at least one tutorial in the Tech Tips section.
No good. My caddy runs like a dream minus this stalling bulltucky I'm dealing with. Short story, I started a new job last night and my car stalled while pulling IN to the parking lot. I crank it back up and literally drive 50 ft. through the lot and it stalls again as I'm coasting towards a spot to park. Two stalls within the length of a McDonalds drive through, right in front of all the new people I'm about to meet. Good first impression huh? I ordered the sensors so I'm waiting on those to arrive and I'm then I'm going to tackle the job. I'll report back when the job is done with some hopefully positive news. Might take me a while though, Wisconsin is gettin' chilly and I hate working on cars when it's cold. Hell, we're expecting snow next week! I need to invest in a heated garage. Thanks again for the help everyone.
Just an update. I have the sensors but I have not changed them yet. I park my caddy for winter so I planned on doing it once the snow fell. I'm still stalling every now and then, but I've grown to rev it up a little at stops so it doesn't die. I got on the gas a little bit today and P0101 code popped up and my car started running like crap. That code is a MAF code. Could that have been the problem all along? Like I said I have cleaned everything spotlessly and am still stalling and now getting the MAF code. Do I get a new MAF and hold off on the CKPs to see if that stops the stalling? I can reset the codes and it runs like a champ again until I rev it up pass 5k rpms and the MAF code pops.
