Hi All,
I recently have been having a stumbling issue during acceleration and or reving the engine. Before a couple days ago the LC was running great. I have checked a bunch of threads in which this one seemed to be on the right track but I wanted to verify and get any thoughts with you all.
I have a 1984 FJ60 Desmogged by me following the desmog guide. Carb and Dizzy have been rebuild by Jim C within the past year. I have replaced all of the existing vacuum lines as well. I have a new fuel pump (three months old) and a one year old fuel filter. Over the past year my tachometer has been working intermittently which I assumed was either a grounding problem or a broken tach. I separated the green tach clip near the ignitor/coil. It seemed to work better yesterday. Today not so much when I tried to move the LC. It idles fine and runs with choke out well... just stumbles with choke in during accleration. My vaccuum off the brake is around 17... I live at about 7K ft.
I also checked the solenoid on the deceleration fuel cutoff and it clicks when unplugged/plugged in and the solenoid there was loose/not grounded well and now it is which I thought also may have fixed the issue yesterday but now no go. This was recommended in a thread by @OSS
Does this sound like the Emissions Computer or would the green wire/white wire mod be the solution? Let me know what you think or next steps could be. Thanks a bunch for your time.
