My 89 SC 5spd. Wont hold an Idle. I put new plugs N wires on. But it sat for 4 yrs. after I put new water pump on. She only runs when I keep hitting the gas pedal on N off. Stop doing that, she shuts off. I drained the gas tank. But maybe it`s the gas left in the Injectors. So, I put Injector cleaner in. Any Help here??. The plug N wires were put in after it sat.
 
DEFFINATLY ....check vacume lines .... mine did the same thing ...

just use some RTV silicone between the joints ,,
 
maybe IAC motor? Pull the plug on the throttle body and if it runs like normal the your IAC is bad if the car stalls then the IAC is fine
 
If it wasn't doing this before, it could be something simple like just not having a proper seal around the intercooler joints. It takes a few times before you get a feel for a good alignment at the intercooler.

sitting for 4 years isn't good for the fuel in the tank either.
 
Idle problems

I have an similar issue with mine sometimes after its warmed up when I go to restart the car it sounds like if its missing fire all I do is give it WOT and then it run normal, does anyone have an idea what that could be?
