Hello, my mechanic is finishing up a rebuild of my cars FI system, and we cannot get it to work. We have some parts we know are broken, but replacements haven’t worked either. Are there any known sources for these?
-Manifold Pressure sensor (known as the 'grenade') -Air bypass valve The issue that we are experiencing is misfiring and lack of power in the top end. Apparently they have tried 3 sensors to no avail. It is a ‘74 2.0. Thank you! |

Adjust valves, adjust dwell, adjust timing. In that order. I agree with Rand. Sounds like spark,timing, dwell adjustment, Etc. Adjust timing with distributor vacuum unplugged and capped
