I need your help...I've got my transplanted djet 2ltr (76 de-smogged motor) in and running...and driving. I'm trying to get the motor running good but I'm having a problem with low rpms.
If I try to slowly accelerate the motor seems to "buck," hestitate until the motor reaches about 3,000 rpm then it's smooth sailing. However, if I put my foot into the pedal harder and run through the gears it pulls hard and strong like a mule....awesome. Below are some things I've done:
The only other symptom worth mentioning, is when I first start the motor when it is cold, the idle hunts quite a bit....like 1000 rpm...not to sure what that is all about. I did install a oem thermostat and the air flaps are working correctly. After it warms up the idle is fairly steady but a bit rough. Sorry for the long story....I need some ideas |

My '76 2.0 did the same- almost 20 years ago. I called George at AA, and he asked if I had a ballast resistor in series with the TS2. I originally had one, which I had removed since I couldn't find any reference for it. He told me to put it back in. I did, and it ran great and with no problems through '02 when I pulled it for its rebuild.
Yes, I KNOW the ballast resistor isn't supposed to be in on a '76, but it worked. Good luck! |

Well, I do have the 270 ohm resistor still from my spare 2ltr....which happened to be a 75. Worth a try at least...not sure what my stock 043 MPS will think about that...thanks |
