The car, 1974, retains its original FI. Fires up no problem, but, until it warms up it almost dies as the rpm is almost zero, or, it almost dies until the temp bumps up.
When warm it is a nice 800/900 rpms and idles nicely. I tried to do a search but it never works for me as the website is beyond my mortal understanding. Best |

Cold start valve gives an extra burst of fuel for starting when the thermo switch is below a certain temperature, like 35 degrees or something. Are you talking temps like that? The CSV should then close pretty quickly after that. Many people run without a CSV, particularly where it doesn't often get below freezing.
FI is great, but when it hasn't been maintained over time vacuum lines, sensors, and wiring get old and start to fail. Troubleshooting it can be difficult when you've got more than one thing going wrong, as it sends mixed signals / symptoms. Replace the hoses and start troubleshooting / testing things one by one. |
