Fuel Injection Adjustments?

I am new to this forum and new to working on Samurai's for the most part. Since I bought my '90 Samurai about 5 years ago, I haven't really had to work on it except for a water pump replacement. However, it recently blew a head gasket -- so what better time to do the 1.6L conversion? I just finished the conversion last weekend. Having just installed the new engine, I wanted to check the idle speeds. Since the day I bought it with the 1.3L, it seems like the FI system idles way too fast when its cold. It will also "lope" a little when it is really cold outside. Just by listening, it sounds like it is running at 1500+ RPM at cold idle. I just bought a diagnostic tach and plan on checking the actual RPM this weekend. Does anyone know what the idle speeds should be? How are they adjusted? Any ideas what is causing the loping?

Thanks.

Re: Fuel Injection Adjustments?

My '92 idles the same way when it's cold but once it warms up it runs fine. I think the idle should be around 800 rpms. Petroworks has the supplement FSM for the fuel injected Zuks, it may help you out. If you talk with Gary or Rudy they'll probably answer your questions about the idle and how to adjust it.

Re: Fuel Injection Adjustments?

That crazy high idle when very cold is normal. Mine has done it since day one, back in 1994. It might seem like a high idle, but remember that these are lil' rubber band motors.

The "loping" sound when really cold, again normal. It smooths out when it gets warm.

If someone out then can show me that this is not normal EFI Sammy behavior, then it would mean mine has been running crappy since the day I bought it new.

Re: Fuel Injection Adjustments?

My 1992 has a very fast idle on warm up from cold, almost to the point where your thinking about the possibility of an explosion.
LOL

Re: Fuel Injection Adjustments?

Same dog bit me. I just got a '93 EFI and I checked the diagnostic codes on the ECM and it said no problems. One flash, pause, then two quick flashes. Every Sammy I've ever driven idles really high on fast idle.

Re: Fuel Injection Adjustments?

My 91 does the same thing. The looping really isn't normal as it never did it when new. Only after the first 100,000 miles did it begin to act this way. It has been suggested to replace the water temp. sensor (not the sending unit for the temp gauge) and another sensor that I'm completely at a loss to remember, but I did replace whatever it was and still no change. Still have a code 12. It must be possessed by the warm up demons........

Creator, everything we do leaves a track. May our tracks be ones we would want you to see and others to follow......
