How to I set idle speed?

I have a 2000 Olds Alero Quad 4. It runs great and has about 50,000 mixed miles. It has been serviced by the book.
My problem is that it has been getting poorer gas mileage that it shuld be. Maybe 25% worse than when it was newer. Even new air filters do not help.

My thoughts are that it is the idle speed setting is too fast,about 1,000 rpm.I want to try itat about 700 RPM. I can find the throttle cable that controls the air and fues but I cannot see a idle speed setting screw or other adjustment.

Can anyone help me to adjust the idle speed?

Thanks

Jim

Before performing any on-vehicle adjustments to fuel or ignition systems, ensure engine mechanical condition is okay. CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Drive ability problems may exist until computer systems have completed a relearn cycle.
IDLE SPEED & MIXTURE
NOTE: Idle mixture is controlled by Powertrain Control Module (PCM). Adjustment is not possible. After replacement of Idle Air Control (IAC) valve, system must be cycled as identified for PCM to properly control idle speed. If idle speed is not okay after cycling system, problem is usually caused by a dirty throttle plate or vacuum leaks. Ensure all vacuum components are functioning properly.

IDLE SPEED (4-CYLINDER)
Turn ignition on with engine off for 10 seconds. Turn ignition off for 10 seconds. Start engine and idle for 30 seconds. Slowly vary engine speed between idle and 3500 RPM 5 times. Return engine to idle. PCM will now properly control idle speed. 2.2L (Cavalier & Sunfire) & 2.4L (Alero, Cavalier, Grand Am & Sunfire)  Good luck and hope this helps. If it still has the high idle problem, your going to have to buy a can  if not two cans ot THROTTLE BODY CLEANER NOT CARBURATOR CLEANER. Just follow the instruction on the can and try to get the Idle Air Control Valve cleaned also which is on the sdie of the throttle body so go to town when cleaning the throttle body and then do the Idle speed relearn again. The other thing to is since your doing house cleaning, buy a MAF sensor cleaner and spray down your MAF sensor and IAT sensor also, this will help with your fuell consumption. 

Good luck and keep me posted, be glad to help.

2000 olds alero chimes once twice three times and four times when the car is running and in park. the chime stops when in gear then starts again when back in park


Has your Alero been parked for an extended time, or is the weather really dirty where you are? May need to clean all 4 door acentuators...(spray with PB Blaster) and wipe off excess...may be sticking...any interior lights on? Best test would be to dis-connect the battery posts for 15 minutes and then re-connect. (this reset the memory) Any check engine lights on? Hope this helps.

Camshaft gasket replacement on my 2.4L alero


On the quad 4 the first cover is the ingition ciols in the middle of the two cams this cover is expensive so dont drop it the coils are insidit and are in it and the cover on these this old are suspect for missfire and dead cylinders the rubber boots should look like new and if they dont should be replaced the boots should all stay on the cil tower covers if they dont consider replaceing the cover and the boots as 100 thou tune up calls for these and the coils to be inspected and changed if any arcing appears to have happened. Never saw one with over 100 thou that was good unless it was already changed. Weak point on the old quad 4 In was powerful but injector anf head problems and water pump problems killed most of them. I have seen a running one for a few years now I worked on alot of them in the early 90's but they all but vanished by 98 or so After this completed and unplugged and out of the way the top of the engine needs to be carefully cleaned with the plgs still in and then blown off completly and recleaned and blown off till nothing is down in the spark plug holes or any where that dirt can fall into the engine. I was following a person that said they had a 3.4 version of this car and I checked and the 3.1 and the quad four were the only motors so most of the story that applie to the 6 applies to the four also but if the four is a leakers its an expensive motor to work on and most of them died an early death. Most home doers need not go any farther as I'm a master I even I am challenged to work on thie motor. The guys that I knew that worked on these and could hit the book times to fix them are all out of the repair end and at least all the cars are too. theirs a few but not many. They were too powerful for the parts they were made of and self distructed very easy. The 4.1 cadillac and the 2.3 vega all aluminum were worse the quad 4 hit the trash heap even faster as the cars were fsat and driven fast and died fast
