It's going to be either the ASD Relay (they do "fry out" every now and
then), a loose harness (either the ground or on the injectors themselves),
or the PCM. Try the ASD relay first as it's the least expensive
route...after verifying all the injector connections and ground. Injector
resistance should be in between 10-16 ohms (you can check them with a DVOM
while you look at each connector).

Subject: DML: '00 4.7, Malfunction light on, P0203-P0208 codes
I've had this problem over the course of several months now. It starts out
with the engine rev'ing up 300rpm for a second or so and then down, usually
at constant highway speed but has also done it driving around town. This
fluctuation in rpm will continue for a while and then the engine light turns
on. In the past, the problem would go away and the light would turn off
after a couple of trips.
I just found out how to check the codes and did that last night when the
light came on again. I get P0203 through P0208, which are listed as injector
circuit malfunction on cylinders 3 through 8.
Anyone know of the cause/fix for this? I'm driving from CA to TX about a
week from now and would like to fix this if possible.
If not, I'll have to try to get it into the dealer on Tuesday.
thanks,
Dan
