My 2002 Buick park Ave. stalled sometime ago,, i have had the idle control, idle air, and maf, all replaced,, the car runs, now and then it feels like it stumbles,, it has stalled and restarted and ra


when your engine speeds up or slows down the voltage will increase and decrease,, probably has nothing to do with your problem.. Its a 2002 car so first check all the hoses and pipes on the engine that provide vacuum to the different parts of your engine.. check the hose that goes to the brake booster. plug the hose and try running the engine.. If you DRIVE THE CAR YOU WILL HAVE MUCH REDUCED BRAKING EFFIGNCY.. BE CARFULL. to see if you have an internal vac. leak in the booster. Read out the codes to see if there are any set. Your problen sounds like a vac leak to me.. Post here and let us know what you find..

1991 toyota 4runner 3.0 v6 starts runs 5seconds then dies will start back up for 5 seconds ata time


Hi Elmer, I'm glad to help! Elmer there are a lot of things that can cause a dieing problem. FIRST, see if it will stay running if you push the gas pedal a little bit then crank it. If it runs and stays running but dies when you release the pedal then here are a few things you can check. (1) You may have an "IDLE AIR CONTROL MOTOR" sticking and is stuck in the closed position. SOMETIMES this works, take sometime and tap on the motor and if it starts idling properly replace the motor. (2) You could possibly have a "THROTTLE POSITION SENSOR" that bad and does not signal the engine controller that the engine is at idle so it dies. If you can get it to idle then tap on the TPS when its bad it will idle the engine way up while tapping on it. If it does then replace the TPS. (3) You could also have a FAULTY or DIRTY "MASS AIR FLOW SENSOR" If the vehicle has one, some do some don't. If your vehicle is equipped with one, you can take it off and try cleaning the air flow sensor inside it. If it idles properly your good to go. If it doesn't idle properly I wouldn't rule out the sensor being bad. (4) You could possibly have a vacuum leak, vacuum leaks cause all kinds of crazy problems because it confuses the engine controller. If you can get it to idle, then you can take parts cleaner and spray around the intake manifold and if it dies right away then you have a vacuum leak that needs to be repaired. (5) You could have fuel issues, BUT, if the engine runs good while driving it down the road then you can rule this one out. These are the most common problems that occur and cause dieing problems. Hope this helps and have an awesome day Elmer.
