1994 Explorer XLT, 4wd, 160,000 miles, When warm the truck surges when under load, once cruising it's fine, but when accelerating, especially between 20-35mph. Fuel pump is 6 months old, fuel pressure regulator, fuel filter and EGR valve are new. Only code that comes up has to do with EGR valve, I checked all hoses and EGR components and they all seem OK. Running fuel pressure is 31psi, loses pressure quickly when engine turned off. What I get from the repair book is possible injector leaking, but don't want to tear apart unless I know. I have read other questions in this forum about similiar problems with other makes of cars and the MAF sensor keeps coming up. Any ideas?
have the same problem?
