My 1989 Pontiac Bonneville has a cold weather problem: It won't start, it backfires & won't run:
This is one of the nicest cars I’ve ever owned. It currently sits at 370,000 kilometres and I can see driving it past the 400k mark.
This winter a problem arose with cold weather starting. When the temperature hits minus 18C (0F), the engine turns over fine but the car reacts like it’s being flooded. It just about starts then violently backfires and the engine stops dead. I’ve ruled out all of the following (a costly venture to be sure) -- heat sensor, crank sensor, computer, timing chain, ignition module, injectors.
My mechanic is baffled. So am I. Any ideas. Please?
