Hi, No error codes and it runs great x-cpt the engine likes to die when coasting. This can happen at 65mph or 30mph. 8 New injectors 2 yrs ago, new plugs cap and wires at same time. Is there some list I should follow to troubleshoot?
I had a similar problem with my 1992 Deville a few weeks ago. It died when I was coasting around 15mph. I took it to the dealership and the problem turned out to be a plugged catalytic converter. I was told the plugged catalytic converter caused a lack of power to the engine. I had it replaced and now the engine runs smoother and there is a large performance boost. The car hasn't stalled since. I hope this helps.
