I have a 1990 Supercab XLT that I have been restoring, Engine rebuilt, 5 speed Tranny rebuilt, All new parts on the engine. I am still breaking in the engine I have about 260 miles on it so far. I am experiencing random high rpm surges, sometimes when idling and often when I shift gears it will climb to 3000 rpm and slowly come down. This 2.9 doesn't have a Mas flow on it. any thoughts on the subject would be appreciated.
