JCW exhaust
Won't stay running on first start from cold. Very poor idle when it does start, wants to stall backing out of garage. Seems to run rich - smell of fuel and more smoke than before from exhaust when cold.
Have been running Shell V Power, tried Shell 89, tried STP gas additive. All had no effect. Will try 87 from somewhere tomorrow when I need to fill up.
Come back MTBE, all is forgiven.
