Working on a 1974 2.0 d-jet
-symptom 1- when i start it... idle is very low no where near the 1600 rpm as Brad mentions -symptom 2- low idle...like 550 rpm -symptom 3- when coming to a stop it almost dies -symptom 4- stomp on gas when sitting and driving it goes blah... then takes off. -symptom 5- as it warms up loses a little power things to note: -there are 20 clicks when pushing down accelerator so tps is correct -timing and dwell were checked today and they were within spec. -lifters just adjusted |

You did not mention what the fuel pressure is? Should be stock or a pound high is okay too. When you checked the timing, was the vacuum line unhooked and is it hooked up to the "retard" side of the advance mechanism? On 1974 2L D-Jet models it is to pull the timing back to help with cleaner emissions and advance is all mechanical unless you have a dual ported throttle body and in that case make sure the hoses are connected correctly. As mentioned, the butterfly bypass should allow the engine to speed up at idle and you can hear the change in air flow through it when opening it up.
Finally, I would spray some carb cleaner around the injectors at their seal locations so you can be sure the seals are not leaking by. |
