I have a 2005 3/4 Ton 4door 4wd longbox 6sp manual... ... . Have noticed when going down hill on cruise control, engine seems to "surge", but when you go uphill or any slight load, seems to run fine... ... .....
Any Ideas?? it has around 75,000 miles on it, changed fuel filter with no change in "surging", am running a EDGE Mileage box which has been on it for past 40,000 miles with no problem. Use POWER SERVICE additive in fuel... . dont have a fuel pressure gauge, sorry??!!
