1988 Ford Bronco Malfunction - Engine


Question: Hello from B.C.Canada My bronco has a rebuilt 351m with about 45, 000 kms. It runs fine until recently it started loosing rpms while idling at a stop in drive.The rpms drop erratically from 700 to 400 approx.It will stop if I put it in neutral or park.Also check engine light flashs in colder weather about 5 times pause and 5 more until it is warmed up.It does this some days and others it doesnt. I have taken it to a shop that I deal with occasionally, they anaylized it for an hour while it was doing this the whole time and got no codes. They cleaned the I.A.C. motor & passage and even ordered a new one to try it but it didnt stop the problem. They said they dont know what it was and it could take hours or days to find it but I wasnt about to play that game at 75 an hour. I recently changed the plugs, wires & fuel filter, and have tried different brands of fuel to see if it was bad gas still no luck. I have had this problem now for about 2and a half months even though the truck runs excellent any other time. I have to drive 1100 kms in the next month and would like to solve this once and for all. Any help would be greatly appreciated, Thanks. Rob
