Hi. I have a 91 Pathfinder with a little problem. When I first start it, it drives fine for about 8-10 mins. Then it starts bogging down and idling rough below 2600 RPM. The problem goes away after I drive for a few minutes, it takes longer to go away if Im driving at highway speeds. When I turn the engine off for a minute the problem comes back for a minute or two. Ive checked the computer, EGR, PVC, sparks, fuel pressure and looked for any leaks.
On a side note when I checked the fuel pressure I found that I the pressure in the line would never go below 5 psi. Even when I pulled the pump fuse, started it until it choked and turned it over a few more times the pressure was still 5 psi. Just wondering if this is normal.
Any help you have would be greatly appreciated. Thanks in advance!
