cold start problem
Hi all,
I'm new to the sight. I just bought a 1999 S80 T6 and have a problem when cold starting the car. When I start the car it runs really rough, kind of surging, and almost stalls. It only lasts for a few minsthen runs normal. There are no DTC's. Has anyone expirienced this?
Thanks,
Bill

RE: cold start problem
Fuel pressure is good. No spare key. I did have several codes P1172 P1182 and P1238. I replaced the bank 1 O2 sensor 1, bank 2 sensor1was also replaced recently, and the MAF sensors yesterday and the only code that comes back is the boost pressure sensor circuit A low. What's odd to me is that the car has more power with this code active. ? This morninr I had the same cold start problem. It only happens when the car has cooled down and sat for a long time. Engine service urgent does appear in the window after the cold start problem but it doesn't throw a code.

RE: cold start problem
No. It does start but surges. The idle goes from 3k to 8k and if I give it gas, it takes a few sec's before it reves up. When the rpm's are up, 2.5-3.5k, it is smooth. If I let off the gas it drops down and runs rough. I can put it in gear and drive it and it clears out.Does it have a cold start injector?
Thanks,
Bill

RE: cold start problem
I just went out to start the car. I turned the key to on but not starting it, let it sit there for 30 seconds. Turned the key to off, pushed the pedal one time, turned the key to on for 15 seconds and for the first time it started normally. The check engine light also went off. Now I'm even more baffled. This thing is screwing with me. lol. I own a repair shop in Marietta Ga. When I get there in the morning I will pull the codes if they come back.
