I know people always post about this but my 88 2.9 has an idle problem. It runs fine for quite a while then every once in a while it will bog down to 4-500 Rpm and stay around there for a few seconds then jump up to 1100. It did this even with my old 2.9. Its not the fuel filter clogged but it kinda feels like that. And I dont Think its the pump either because it has done this for a year and half and it just now starting to bother me.
 
Mine did that so I hooked up my scanner and had it check the computed timing on it. It was off so it fixed it and all was well. Don't know if thats your prob. but might check it.
