hey guys so heres my problem, i have a 99 s80 t6 with 144,000 miles. lately i have been having problems on cold start, the car will start up and idle really rough and sputter for a couple seconds then it catches itself and idles fine, but then when i go to drive off the car hesitates and has no idea how to accelerate it will bog then immediate accel randomly. so i went to have the car scanned and came up with a p1237 code and the description was accelerator position sensor. i had read somewhere that it can be caused by a faulty bcs sensor. i replaced that plus a bad oxygen sensor but the car is still having issues. i would really appreciate any help with this its driving me crazy i just need to know whats wrong and how to fix it!

 

74 views and NOONE can help me?? i find that hard to believe. Can someone please chime in if you can help me i would really appreciate it.

 

check the idle air control..and clean that up. Search this forum or google how to clean. Its a simple DIY. and see if that helps. Also make sure the engine filter is clean too. Let us know how it goes

 

would that have anything to do with the accelerator position sensor code?
