I have a 75 2.0L with DJET, Euro Pistions, new harness, new CHT, <15K miles on complete rebuild. Before the car is fully warmed up it runs great, but after it is warm the car stumbles over 3500 RPM. I do not have a rev-limiter. Any ideas where I should start debugging this problem would be appreciated.
Regards,
Dan

TPS maybe? Open it and clean and adjust.

Lube the advance weights lately? 1 drop of 30 wt oil on the felt at the center of the dizzy shaft per year is recommended by the factory manual.

TPS is new.

I rebuild the dizzy about 3 years ago, will put some oil and report back.

Thanks,
Dan

Could be one or more of several things. Mps could be not holding vacuum, tps could be mis adjusted ( disconnect to test), condensor break down will give those exact symptoms. Checked your dwell lately?

replace the coil.
