- Testing and adjusting of two idle speed air valves which where both bought on eBay. One good and in excellent condition and ideal for adjustment and the other ready for the trash bin.
This is a direct comparison of these two valves side by side where both brass inserts are pulled out to be flat with valve housing and the current they will draw to close the valve fully
On point. Great way to test and adjust the ICV. For those of you watching this having ICV issues, you also need to check the voltage sent to the ICV from the Idle Control Unit. Should read 12 volts when the engine is first turn on then around 5 volts once the engine reaches operating temperature. If this is not the case, then the ICU should be checked or replaced.
Thank you so much. Just what I needed for my 1990 sl500 r129 series 5.0 l V8. That's awesome I have a high idle on a brand new idle control valve it could not be adjusted right or it could be the overlimit voltage relay I ordered one of those two just to make sure but that's an awesome demonstration that you did I really appreciate it it's exactly and I mean exactly what I needed to see.
Hi on the 420SEL the bypass tube is closed on one end. I don't understand my MBZ would do this. Since you have a 560 it is open on both ends. I made the mistake of cutting mine . So I make a aluminum tube and and flattened one end to close it.
Looks to me like we need 4v at 1amp fully closed. P=IE = 1x4 = 4watts of power to energize the coil in order to close the flap. Or measure the resistance of the coil and ignore voltage and just deal with the current ... R=E/I = 4 ohms. P=I*I*R = 1*1*4 = 4watts
You ned to mayntent the voltage on konstant level to get this correkt. 12v ore maybe higer, 14 v.
What is the purpose of the plastic cap? Is there any problem using my valve without a cap? My cap basically fell apart when I took the valve out.
I have 1992 SL500 lately she has been idling in park mode at 2RPM’S fuel pressure
do you have part numbers for the those 3 rubber pieces I have a 92 500sl Thanks
I have a 1992 300sl, is there a way to ajust my icv?
How do you adjust the idle control valve on a 500 … why aren’t they the same ..??
What size us the screw used to pull on the idle control valve?
Really great video!! Need some help - low idle, around 500 rpm and have been trying to get it up to 700 in gear, with AC on.
