What causes large idle RPM drop from unloaded to in gear?
Idle drop would then be in the 100 RPM range with ‘in-gear’ idle setting coming out @600. A large drop from Unloaded to In-gear idle setting can otherwise usually be attributed to either a vacuum leak or a convertor that’s to ‘tight’ for the engine set-up …
What does it mean when a car starts and idles?
It starts and idles like it is brand new. You can start to rev it up and o ce it hits a certain RPM it hangs there and backfires/sputters/pops/bangs/throws fire out the pipe. I pulled the plug and it was BLACK.
How does idle speed work on a Camaro?
Idle speed screw is 1-2 turns in from when it touches the stop. Air fuel mixture screws are 1-1/4 turn out from seated. Transfer slot has the proper ~0.020 little square exposed. So timing looks pretty good (as good as I can get it), but I still have a huge rpm drop from 1,000rpm in park to 600rpm in gear.
What’s the RPM drop from Park to in gear?
I am experiencing a large rpm drop of approximately 400rpm from in park (1,000rpm) to in-gear (600rpm). Medium/light dizzy spring combo (light/light spring combo gave advance at idle) which saw 32 total timing @ 4,000rpm and 34 total timing @ 4,500rpm.
Why does idle RPM drop from Park to in gear?
A large drop from Unloaded to In-gear idle setting can otherwise usually be attributed to either a vacuum leak or a convertor that’s to ‘tight’ for the engine set-up I agree with John. I also believe the initial 22° timing is too much, more like 12°. Tune carb with a vacuum gauge at a lower curb idle.

What kind of engine does a Yamaha Raptor 660 have?
This is what a Yamaha Raptor 660 owner wants to know and he turned to the ATV AnswerMan for help. Here is exactly what the reader asked the ATV AnswerMan, followed by his response: I have a 2002 Yamaha Raptor 660. I cleaned the carb and all the passages with cleaner and forced air, replaced jets, fuel needles, seats, o rings, and fuel screws.
Why does my car shake when I put it into gear?
Car shakes when put into gear, fine when i give it gas, I… I had issues with my car shaking in idle and when putting it into gear, so i replaced my mounts, now when I put it into neutral my car doesn’t shake anymore but when i put it into gear, and especially reverse, It shakes badly.
Why does my car shake when in idle?
After having my car serviced for oil change, tire rotation and air filter replacement, as I was leaving the service center my car had a new engine vibration/shake while in park or neutral in idle. If I rev the motor to 1000 rpm the problem seems to go away. I am not getting any engine codes.
Is it normal for a car to run rough when idle?
I can say your car isn’t likely to suffer a catastrophic failure because of this. With a condition such as this, it is normal for it to run rougher when electrical components are tuned on and it is normal for a car to run rough when the idle is to low.
What should the idle RPM be on a Camaro?
Tune carb with a vacuum gauge at a lower curb idle. Stock cam should give about 18 inches at unloaded idle and a drop of about 150-200 rpm loaded. I agree with John. I also believe the initial 22° timing is too much, more like 12°. Tune carb with a vacuum gauge at a lower curb idle.
