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 |

Not sure about the dizzy hoses, some one will chime in (I don't have a manual at work), but here are a few dx tools:
1) if adjusting the idle air bypass screw has no affect then you have a vacuum leak. 2) check your spark plugg, they will tell you if you are rich or not and will tell you if it is a setting issue ( all dark or light) or a focal issue (1 or 2 off color) |
