Lt1 idle problems/ need help
I recently swapped a 95lt1 into an 85 s-10. I'm havin an issue with starting and idle control. If I slightly hold on the gas and keep it at 1000 rpm's or higher it runs great. As far as not touching the gas, it won't start or idle. New to the whole computer controlled thing and any help would be great

Check the O-rings on the injectors. Spray some starting fluid around the injectors and see if the idle changes. Make sure the spark plugs are good and wires are setup right and not burned.
Check the Maf too, unplug it and see if that makes a difference.

The section on shoebox says to let off of the throttle and let run for 5 second then turn off... If I let of the gas the motor will die

Re: Lt1 idle problems/ need help
Once the motor is running, I unplug the IAC and there are no changes. Does this mean it needs to be cleaned or replaced or is that suppose to happen... Please forgive my ignorance. This is my first go round with all this computer crap... Should've thrown a carb on it and forgot it... Lol

Re: Lt1 idle problems/ need help
the idle is supposed to be controlled by the IAC
some of us who don't have time at the moment have turned the allen screw and manually bumped up the idle untl we could go back later and fix properly
my issue was O2 sensors when I bumped mine for a week until i replaced them

I would look into checking the IAC and the TPS sensors.

never is a long time
please note that i said i turned mine for 1 week before i could repair properly.
It's not that it causes issues with the computer because that is just running an image. If you datalog you can see that the IAC isn't all the way closed when you turn that screw.
