enigine wont idle
Help,
Yesterday I had to move the car(88 vert) first time this year,needless to say battery was flat. Had to boost from an optima from my shop. After a quick move I replaced the dead bat with the optima till I get a new one from the general. Since the change the car is hard to start and will nt idle without feeding it throttle. I guess my question to all is after I leave the bat un hooked all night will it return to norm with a fresh bat or do we have other issues. FYI the car has 14,300 miles on it. Any and all assitance would be a great help
thanks
Murray

Leaving the battery disconnected all night won't make any difference to how the engine starts and runs.
When the battery went dead, the ECM lost it's memory, but that shouldn't have caused the problems you're experiencing. The engine should still be able to start and idle without much trouble.
I believe the cause of you starting problem lies elsewhere though.
One of design parameters of our engines is that they be brought up to operating temperature and, preferably, driven frequently. At the very least once a month. When this isn't done, all sorts of running problems can result.
If the engine has sat for a long period of time, I'd change the fuel filter and pump in fresh gasoline. I'd also pour in bottle of injector cleaner - Red Line is good - to HELP remove any gun deposits that may have formed.
If those two things don't cure the problem, we'll need to start looking at the electrical and mechanical ends.

A quick update. It seems baby prefers a battery from the general. I charged two other batterys and installed each. With each the engine would not idle. There were no codes so just for shi*s and giggles got a new delco from the general.Installed started idles great wtf. Its seems that each car has its own sets of rules..
Thanks for the help

Now THAT'S going to start problems. When the word gets out that Delco batteries, especially those bought at a GM dealership, make the engine idle better. Throw your scanners away, guys, just buy a Delco battery. Preferably from a dealer.

Or will any GM dealer do? What if the dealer handles more than one brand of car? What about a multi-car dealer with a foreign brand? I can see where this could get very technical. Gotta do this right!
