RE: P1621 fault code - but my car has been off the road... - 3/3/2008 2:59:05 PM    ken@britishparts.com   Posts: 1795 Joined: 5/11/2007 Status: offline Without the steering condition, go back to Keith's suggestion on ignition coil.  Look for signs of leakage on the under side of it.  Sounds like Keith is dead on.  It hits up and cuts out / cools off and runs again. As an outside thought (and I mean way outside) check the resistance on the battery cables.  The computer feeds directly from the battery since it's more stable.  Maybe resistance is building? _____________________________ Ken Karr Motorcars, Ltd. 800 338 5238 x626 www.motorcarsltd.com (in reply to Pammyjz) Post #: 11
