I have a 87 dakota with a 3.9l It runs really rich and wonts to die when I come to a stop if its not in nuetral. I have rebuilt the carb replaced the cataletic converter, the exhaust manifield on the drivers side the o2 censor,the fuel filter, spark plugs and wires cap and rotor, the timmin is good. If you have any suggestions I would sure appreciate them.

 

get that ****ty motor out of there, I've had nothing but problems with my 87 3.9 carboreted... I've changed everything, its just a POS. I've changes the cat and muffle the plugs wires cap rotor spark box coil rebuilt the carb and its just a pile of junk. How many km's ?

 

It has 214,000 miles

 

mine had 239,000 kms. If you really want to just keep it running. adjust the 2 mixture screws at the bottom of the carb turn them both out 1/2 a turn at a time and see if it helps.

 

there are no mixture controls on the carb. From what im told its all internal with is a pain in the ***.

 

Is it throwing any engine codes?

 

my check engine light has never come on

 

hmm.. i would try to see if it will read out any codes.. turn your ignition on then off then on then off then back on and watch the light and see if it will throw any codes..

 

you sure its carb'd and not throttle body injected?

 

im sure it is carbed I had it rebiult last year
