Just curious, how does your car run when you first start it, with it plugged and disconnected?

Also, I just noticed you are from Argentina. My mom was born there, in Buenos Aires too. They left during the Peronista regime, but really cool country.



My car has several problems with the ignition system. I changed injectors, distributor, some vacuum lines are disconnected and have to be reinstalled, etc. Until I fix everything it's not going to work well. In any case, starting with or without a cold start valve should be the same, because the average temperature in Buenos Aires is not too cold. Speaking of my country, it is very beautiful, but unfortunately Peronism has been ruining everything for several decades. I understand your mother. Many people have left and are currently migrating to other countries, because the situation is getting worse.

A few years ago I tried disconnecting my cold start injector. I was in warm weather (summer I think, in CA).
The car took an annoyingly long time to start. I fiddled with the ECM tune hoping I could patch that problem out, which might be possible, but I failed so I plugged it back in.

It seems that a lot of people talk about disconnecting it in a warm climate but that caused an obvious negative reaction on my car. It still started of course, but not well.
Even when warm the CSI adds a little fuel, and it's more atomized than what you may get from the port injectors.

I'm in Colorado, but had an experience with this similar to armos - with the CSI disconnected, my 88 GT would start, and start reliably, but had to crank far longer before it caught. It started much more quickly with the CSI, so it stays connected until I swap to a 7730 ECU (soon, I hope)
