Once it is up an running does the voltage bump up too?I am having a problem with my vette, it is having trouble starting and staying idle. I have to give it a little gas to start it and to keep it running? My voltage guage is also reading about 1 v low when this is happening?
Could just be the weather, if it smooths out after a few minutes of running.I have a 92 Corvette. 5.7 liter LT1 The voltage is normal while driving down the road. The only problem is when I first start it up. It will sometimes not idle well. It seems to happen more when it is cold out too. After driving it a bit though there is no problem. So is it just a weather issue?
One of the first things I got! lol with my efi C4! Good call!The 1st diagnostic tool a corvette (w/ efi) owner should have is a fuel pressure gauge. Check pressure while running, & make sure it holds pressure when engine is off. This tells you the condition of the f. pump, & if loosing pressure, what to check next, like the regulator or injector(s) that are leaking down.
