Help? 5.3L Start-up speed I put a 2001 cable-throttled 5.3L in my '69 Chev. 4WD a couple of months ago. It has a 700R4 trans. The engine speed at start-up is way too high - just for 3-4 seconds and then down to normal idle speed. It's bad enough during this time of year but when it turns cold, I sure don't want it revving this high first thing after it's sat all night in the cold. Can the PCM be programmed to lower the start-up speed or how do I adjust it? Thanks in advance.
