Re: surging idol?????
I have the same problem. I have a 2001 ford f-150 with the 5.4 liter. it seems to do it more after its warmed up. I will be driving and when I go to slow down it bucks back and forth. I notice more around 30 mph. I've checked the spark plugs and the coil packs and they check-out ok. I've changed the air filter and plan on changing the fuel filter. I dont know what else it could be either cause there is no engine light on.
