I have a 2000 dodge dakota with a 4.7..bout 85,500 miles on it..in the last week, the computer read the i lost 4 injectors, p codes 0201,0202,0207,0208 also with a p0171 code. I replaced injectors on 2 and 1, and switched the injectors from 7 and 8 to 2 and 3 the other day. Today it read i check engine code 0206 but the other 2 codes didnt come back. I check the fuel rail and it was clean as a whitsle. I have no idea whats going on, anybody have any ideas on whats going on?

 

Check the fuel injector wiring to see if it isn't faulty and that each wire has power. I had the same problem with my 93 and I cleaned every injector and still my engine wouldn't fire right. So as I looked closer I noticed the contacts on two fuel injector wires were burnt and I had to get new connectors. Also it's possible one of your injectors maybe clogged even though you clean them. Try resetting the PCM and see what happens.
