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 |

If you have a throttle body with ONE hose nipple then the vacuum line goes to the retard side of the advance mechanism or side closest to the cap. If you have TWO hose nipples then check to see which one has a vacuum at idle and hook it to the retard side and the other one to the advance side. On our 1974 it originally had two hoses as many do but ONE nipple and the advance hose just was laying on the intake plenum. In the "old days" this would give the smog check people fits but was factory.
You can and probably should open the bypass screw a little and the idle will come up, it does NOT need to be closed. |
