Question for the brain trust; 2004 1500 4.7 with a 5 speed, start is normal, normal idle speed. Start moving and push in the clutch, it will idle around 1500 until I come to a stop and then Idles down to normal. Seems like the faster I go, 4-5 gear and push in the clutch it will idle around 2500-3000, as I slow, in natural, rpm follows MPH, until I come to a complete stop then it idles normally. I did notice a couple of times, around 30-50 mph, with the clutch pushed in, RPM would drop to about 1500 and then come back up. Any help would be greatly appreciated.
No, I can step on it in neutral and it idles back to normal in a few seconds. So far I’ve changed the idle air control valve, throttle position sensor, cleaned the Mass airflow sensor and cleaned the throttle body.
new problem, not a daily driver, a couple of times this summer had erratic idle with the A/C running, threw a P0507 code "high idle" then it started this about a week ago.
Ok, MANY things can cause idle issues..... PCV valve, EGR valve, vacuum leak, failing IAC, etc...... That is gonna be a fun one to find..... Probably need a high-zoot scanner than can manually activate some of those systems.....
