How to i adjust the idol speed on my 1985 cutlass supreme? I do not have a gauge for rpms.. but it just sounds and feels to high.. i've cleaned the throttle body and everything.. what piece do i turn or...


On some models the TBI cannot be adjusted .Usually these functions are carried out by the Idle Air Control valve ,the Throttle Position Sensor and the power control module.Any kind of adjustment will cause false signals to the PCM.I would take it to a local mechanic and have him test your rpms at idle that will give you a rough idea where running at.That way you can find out what the recommended rpms are and see where you stand at that point.most of this can usually be tested at your local autoparts store depending what area your in.

It reves up real high when its cold after it warms up it has major power loss and backfires throught air tube


Sounds like a blown intake gasket. The expansion and contraction of metal from heat would cause the high idle cold and power loss when warm. Use Carb cleaner and spray along edges of intake to see if rpms change. Take your time. Sometimes, unplugging the idle air control will help you find the leak.

Cold Idol problem/ Bad gas milage


check the cylinder pressure. Mine does the same, and is suspected to be due to a worn cylinder or worn valves leaking. (do your valves click too?) Supposedly, the leak in pressure is causing less efficient combustion which leads to the fumes and slight loss of power / MPG. I haven't been able to open the engine to test mine yet. I am waiting until I can put in new valves, etc. before I go in.

The other thing that you may want to check is the thermostat. When my got stuck open a few years back, it had similar symptoms. Turns out when started, the engine wasn't allowed to warm up to normal operating temperature because the cooling system was triggered by the faulty temperature sensor to try to cool the engine down. Once it warmed up everything was back to normal. The most noticeable thing about this is prior to the problem, the engine would idle really high at start up for about 30-45 seconds, then settle into it's idle pur. One day it just started and immediately went to idle, and sometimes would require gas to keep it from stalling. The problem would not occur if the engine was warm. Putting in the new temperature sensor solved it.
