1978 Bronco Ranger XLT, new C6 rebuild, 351M with Xtreme Energy Comp Cam Kit, Holley Truck Avenger 670CFM.
I have a problem here folks.
This was a problem before all this work of the engine and tranny. I was hoping the rebuild on the tranny would fix it.
I can start my bronco......let it run for 3 or 4 minutes (idling at 1100 RPM)......put my foot on the brake, put it in Drive and that will kill it!
I have to put one foot on the brake and one foot on the gas pushing it up to about 1750RPM before I can put it in gear.
When I come to complete stops I need to feather the gas to keep it running on the street usually. Even when warm.
Idle is set at about 1000RPM.....I love the sound of the engine idling at 800RPM! Wish I could pull up to stops and have it thumping at 800RPM and not worry about it dying.
Here is a video of it warming up:
....you can see me step on the brake, and hear me put it in drive. The truck jumps a bit and then dies. 0:31 and at 2:30 I try it a few times....around 2:53 I get it into Neutral and it idles fine but then at 3:21 I put it back to Park get pissed and try waking up the neighbors.
With the feather method, Drive will jump and want to die for about 15 seconds and then I can let my foot off the gas usually and it will idle in drive at a stop. (1000RPM)
I guess my questions are, as follows:
What should a 351M idle speed be set at with the mods I have? (would it be odd to push the idle to 1350-1500 range?)
Are there any items to look at to help cure a warm blooded engine? Could it be vacuum? Could it be Jets in the carb? Could it be the torque converter? Not sure what the job of the torque converter is but I know with some cam kits they recommend changing the torque converter.
Thanks for any insight. For now I will have to let it warm for 10 minutes or so until I actually see the gauge move up to normal operating range. Feather it here and there when needed. (when putting it into gear and at stops)
I hate wasting gas on the 10 minute warm ups!!!!
