This regulator sits atop the motor and uses engine heat to adjust the fuel plunger inside the fuel distributor and changes the fuel mixture. A faulty regulator will disrupt the correct fuel mixture to the engine. The unit can be tested by measuring fuel pressure as the engine warms up. Figure 7. Warm up regulator. Step 6 – Inspect the idle Turn off the fan motor and AC Compressor during idle adjustment. Start the vehicle and allow it to idle to warm up the engine. The factory manual specifies performing the idle adjustment with the engine oil temperature between 70 - 90 °C (158 - 194 °F). The factory measuring device uses a probe which inserts into the oil dipstick tube. To set the timing you have to set the idle at 750, but to set the idle at 750 timing has to be correct, which it is, but it's set at a higher idle. So I'm hoping i'm not pissing in the wind trying to tune the carb with the timing set at the 1100 rpm. If so I'll have to order a diagnostic tach and start over. Buy Now!New Idle Air Control Valve from 1AAuto.com http://1aau.to/ic/1AISC00031The idle air control valve keeps your engine idling properly, If the valve get A/C Idle adjustment Solenoid. Just installed a Vintage Air A/C unit in my 66 Nova Wagon and when the compressor is on, it will idle down and die.My 1978 Camaro had a Solenoid that would bump the idle up a little to compensate for this.Any recommendations on this subject would be appreciated. Mark. Do you want to know how to adjust the idle speed of your Honda CRV to make it higher or lower according to your preference or driving condition? Watch this video to learn the simple steps and Members Ride. VY EXECUTIVE S2. Feb 26, 2012. #2. I don't think you can adjust it. Is it idling too high/low? Because if it is, AFAIK the idle is controlled by ECU, so something else must be causing it. I shall stand corrected if I'm wrong, though. "Ah well, I suppose it had to come to this." 5. This will set the blades close enough to start and warm up for final adjustment. We just want the engine to idle, if it is high that is ok until it warms up if it is low and wont idle go in a small amount on both screws until it will idle. 6. IDLE RPM: 880 TARGET IDLE AFR: 13.6:1 ANY ADJUSTED PARAMETERS & WHY:-Added 15 to LOOP rate up and LOOP rate down IAC settings (IDLE CONTROL), which (when revved, or warm started) allows and helps get a quicker return down to my commanded idle rpm. ~Default settings gave me a "hanging idle". May 15, 2017. #5. Going back through my old pics, someone removed your ac idle-up solenoid for some reason, but this is what it should look like installed on your carb. AC Idle-up diaphragm is top-left in this picture: It is above and to the right of the float bowl sight glass, with linkage: Johnny C - KK4HAN - TLCA# 17825. That is actually the idle-up system for the AC. That's separate from the other idle-up on the side of the intake manifold. And, yes, the part circled in red can be adjusted to control the amount of idle-up when the AC is on. If you have an ERG system it would be to the right of your picture. Details are as follows: 1999 Honda CR-V. Model: RD-1. Engine: B20B (distributor ignition) Vehicle came in for idle & engine stutter issue (idle rpm would drop & then recover). Especially when AC turned on. No check engine light on, scanned & no fault codes. Mechanic found engine oil had leaked past spark plug seals & into spark plug holes. The geocity link describes a wire running to the ECM that tells it that you have the brake pressed which causes it to cut the flow to the fuel injectors when the idle is too high and you're trying to stop. That's what causes the up-down-up-down of the idle. How to repair Bad idle speed problem in car. RPM go up and down. How to repair Bad idle speed problem in car. RPM go up and down. When I turn on the AC, the idle speed drop's about 150-175 RPM and I have it set to idle at about 700-800 with the AC on and the car warm. Those numbers are with the kicker in place and functioning. The bigger "issue" I have with the replacement is the RPM's take a long time to stabilize as it kinda hangs. KeD4.
