the exhaust gas recirculation (egr) valve sends some of the engine's exhaust gases back through the intake system to lower the vehicle's emissions. over time, the egr valve can fail in the open or closed position. an egr valve that is stuck open can result in an air-fuel mixture that is too lean. this can cause a rough idle.

Check and set idle to your driving preference. Put the car in gear and apply slight load, (AC on) and set the Idle as you like it. Don’t set it too high, as this will cause causes excessive clutch and brake wear. The Idle only needs to be 7 to 900 RPM with light load or AC on.

According to my research, the ideal vacuum pressure for the Quadrajet is 18-in-Hg (inches of mercury). I adjusted the idle mixture screws and the best reading I got was about 17½-in-Hg. The gauge needle, however, was somewhat erratic so I concluded that this was due to a discrepancy in the mixture screws. Yes, I should have adjusted the idle.

If there is no leak in the booster, not much air is sucked out. If you have a leak, depending on the size of the leak, air continues to enter the manifold as long as you apply the brakes. There is a one way valve in the hose between.

Check your charging output at idle and if its low put a charger on while its running to see if it clears up and starts firing right.Id check the connections for the ignition system and make sure the msd is run directly to the battery.Also if your alt has a bad diode it can cause an ac ripple through the system causing your msd to malfunction. 7.

Either this and/or a vacuum leak (hoses, intake gasket, throttle shaft, etc.) If the throttle plates are closed and the engine is still idling high, then it's got to be getting the necessary air from somewhere else.

If your powertrain control computer is misreading idle speeds, this can cause a high idling malfunction. When your car’s throttle is malfunctioning, this can cause your car to stall or idle high. Often this is a result of dirt buildup in the air intake. Other times it can be a problem with a cracked intake tube.

Use a vacuum gauge to tune your idle mixture for the leanest setting that will pull the highest vacuum at idle. while idling with the vac gauge connected, turn each idle mixture screw out 1/4 to 1/2 turn at a time and let the idle stabilize again. Continue to richen the idle mixture slowly until you find max vacuum reading.

What causes low oil pressure at idle? Damaged oil gauge switch, wrong engine oil, faulty sending unit, leak in oil line, deposit in oil filter and pump or even worn out engine parts can be responsible. A common cause is the oil pressure sending unit. The sending unit is a small gauge that sends oil pressure information to the dash gauge.

Why the engine ran rough at idle. So here's what I figured out was happening to cause the engine to not idle properly. There is a switch in the throttle position sensor that is supposed to be triggered when the throttle lever goes to idle to tell the computer to idle. But since the linkage didn't go to the stop, the idle switch wasn't.

Performance Level 1. Level 1 indicates a good stock replacement camshaft. These profiles are designed to enhance throttle response and low end torque in vans, trucks, passenger cars and mild marine applications while delivering fuel efficient motoring. High vacuum, smooth idle and maximum efficiency are characteristics of these cams. Sep 21, 2022 · Activated VA at idle means you ignite this slowly burning mixture sooner giving it time to burn fully in cylinder. In case of no VA at idle that mixture would burn also in exhaust, manufacturers used this effect to reduce emmisions, but it hurts performance. It is normal to see about 35-40 degrees of advnce at idle speed. Last edited: Sep 23, 2022.

My SBC 350 (GMPP 350/290 HP) is running slightly rough at idle, and under moderate load acceleration (about 2k RPM) it feels like there is a definite miss/vibration. I checked idle vacuum and it is 15", with a fast needle fluctuation of about 1" of vacuum. This engine has always had relatively low vacuum, which is probably due to its 222/222 duration cam.

Open Syslog Viewer and make a test call to see if the call is reaching the SBC. If you do not see any evidence of the call coming in, there is probably an issue on the provider side. If you can see the call reaching the SBC, check for the response codes sent by the device to determine why the call is failing. Calls Failing at SBC:. Consider using ATI P/N 917782 as it measures 1.200" in width (for internal engine balance only).

This means that LS1 compatible ECUs can now be used on 24x equipped SBC engines!. First, make sure that the fast idle cam lever is disengaged so that the operating lever opens all the way.

I just rebuit my edelbrock 1406 carb with electric choke and I cannot get it to idle. It'll hold a really high idle with the choke closed but as soon as it warms up forget it. Adjusting idle screws seem to have no effect. I can get it to stay running if I feather the accelerator. What's wrong with my carb?. The biggest cause and easiest to fix is an engine misfire. This is probably the main reason as to why most engines will have a rough idle. Every car contains at least 4 cylinders some up to 8 cylinders. Each of these cylinders provide the help of combustion of gas and air.

As coolant burns in your combustion chamber, it will leave tiny white deposits on your spark plug usually around the ground strap and electrode. Other problems can cause these white deposits so this isn’t a conclusive blown head gasket symptom but if others are present it could give you more proof. Low Cooling System Integrity.

If you experience pinging just off idle you should lower your initial advance. If your motor pings around the point you reach total advance you have two options; lower the total advance or put in a heavier big spring to delay the total. If its pinging well above this point you will need to pull back the total.

The car is surging at idle, from 1k to 2k RPM. I cleaned the throttle body and the IACV valve and did not help. Replaced the IACV and did the idle relearn procedure and still doing the same. Replace the FICV that right below the IAC and improved a little. It now starts at high RPMS, then starts to surge for s few minutes, then stays between.

Your engine should idle high (1000 - 1200 rpm) until either the choke warms and shuts off the high idle cam on the carb or like stated you hit the pedal to reset the high idle cam. I am assuming your carb has an electric choke.
