I may have posted this under a different section but it was in relationship to the brakes.
My 68 Fairlane 302/C4 has four manual wheel drum brakes. The problem was at red lights I'd have to put the car into park or neutral or stand on the brakes really hard to keep it from lurching forward.
I wondered if the idle speed had anything to do with it. Maybe it was engaging the torque converter when it shouldn't.
I had been using this Sunpro tune-up tach to set the idle speed but found it very inaccurate.
So I acquired this Sears engine diagnostic meter through a trade that most people said was a piece of junk. But the tachometer is spot on. I compared it to my Subaru's tach and it was right on the money.
When hooked to my Fairlane it said the idle speed was 1200 rpms in park!
With the engine was hot and fast idle circuit disengaged, I bumped the idle speed down to 550 rpms in drive / 700 rpms in park and now my lurching problem has gone away!
Anyone know what the idle speed should be set at on a 302 when the engine is cold/first started? I still think it idles too fast when the fast idle circuit is engaged. Even with my foot on the brake, it want's to bark the tires when I pull it into drive or reverse. Thanks.
