The car is a '74 2.0l, trying to fix all the items wrong after purchase.
Have found the following items bad and have replaced them: - MPS - AAR - Decel Valve - CHT - Spark plugs and wires I have a bogging/lack of power at about 3000 RPMs, I assumed it was the TPS. But, testing it with the 20 click method I get all 20 clicks consistently. My question is, is this a valid test to ensure the TPS is good? And if no, how else should I test it? And if yes, what else could be wrong to cause the problem? |

The clicks are a good method. If the TPS is shot you can get a complete cut at cruise or the loss of clicks. Is the bog you mention like a carb or does it feel like a complete engine wide miss?

Feels like a complete lack of power, and if I continue to push on the accelerator it eventually causes the car to jump forward/or feel like its accelerating, but it never feels like it has the proper power. |
