CAR STARTS EASY, BUT WON'T HOLD AN IDLE & DIES OUT
CAR HAS BEEN SITTING FOR A FEW YEARS. THE IN TANK FUEL PUMP & FILTER HAS BEEN REPLACED. THE FUEL INJECTORS WERE TAKEN OUT & CLEANED. NOW THE CAR STARTS EASILY, BUT WON'T IDLE. CAR ACCELERATES SMOOTHLY. THANKS FOR ANY HELP ! 1986 OLDS. DELTA 88 ROYALE 3.8 V/8
Has the gas been replaced?
YES, TANK WAS EMPTIED & FRESH GAS PUT IN. WHEN THE NEW TANK PUMP WAS INSTALLED W/ NEW PUMP STRAINER & FILTER.
Check the idle air control. Looks similar to a C battery and its black on the throttle body. Pull it off clean it really really good with carburetor, or brake cleaner. It may be gummed up or stuck shut in its closed loop mode and that would choke the engine with gas.
THE IAC HAD HI-RESISTANCE. I REPLACED IAC & PUT A BOTTLE OF LUCAS INJECTOR CLEANER IN THE TANK. I STILL HAVE THE PROBLEM OF DIEING , NOT HOLDING AN IDLE ! WHAT ELSE CAN I CHECK ?
Have you checked for vacuum leaks? Get the gauge hooked up and get it to run at the lowest rpm you can. Come back with the rpm and vacuum it pulled
I FOUND A MAJOR VACUUM LEAK, SOLVED THAT & IT'S IDLE IS MUCH BETTER. NOW I'M DEALING WITH SUM MINOR ELECT. PROBLEMS ! THANKS
Nice where was it leaking and what are the electrical problems?
VACUUM LEAK WAS MAIN LINE GOIN BACK TO BRAKE BOOSTER. NO TAILLIGHTS, BUT HAVE BRAKE LIGHTS. NO FRONT TURN SIGNALS & NO DASH LIGHTS. COOLING FANS DON'T WORK .
