I have a po460 with cel that comes on every few weeks. This has been intermittent for a few months. I have read up on this and know some possibilities for this problem but haven't addressed the problem yet. Now over the last week I am having a problem with the engine stalling at around 3200 rpm in neutral or park but on the road there is no stalling at any rpm. I have checked that plug wires connections are good and did check spark plugs and they all are at 0.044 " and look like they have been firing normal. Also checked fuel pressure. With key on is 45 PSI and 60 psi with truck running. I increased the rpm to 3200 where it stalls and fuel pressure is still in the normal range of 60 psi. I would only be guessing but my thinking it is one or more fuel injectors, a coil pack, or a fuel pump. Any help would be appreciated. Thanks kev
