I have a 1998 dodge dakota 3.9l v-6 mag..... here is my problem. my truck is running super rich and it has no power....it won't move over 10 mph ....i have had it at 5 diffrent shops that are all dodge certified and they have all done diffrent stuff. The first shop told me the cat. converter was bad along with the o2 sensors so i had them change all that. .... It didn't help.... still had the same problem. The second shop ran the codes and said i needed a tune up and a new tpi, map sensors....so i had them change all that....new plugs, wires dis. cap button and both sensors.... still no change. the truck still runs crappy. The 3rd shop told me i had 3 bad injectors...so i had them change all 6 of them......still no change...still running bad. so i went on to a 4th shop and these guys ran the codes and said there aren't any codes so there can't be a problem...i ask them to run a compression test...they said all 6 cyl. come back fine...so needless to say....the problem was still there no power and still running super rich and won't excel over 10mph.....so now we're at shop 5 these guys told me that it " has to be the throtel body so i had them put a new one on.....you guessed it...no change still runs crappy...super rich and won't excell over 10mph....... PLEASE HELP....I"M RUNNING OUT OF MONEY>
I could have bought a new truck but i love this one.
