I had the same problems with my Acura Legend. On the problem with the running hot and the idling up and down, your cooling system is low. Fill your cooling system start it up and look for leaks, steam, or etc. repair and refill and your problem should be cured if the cooling system is full. At this time i'm working on the other problem. Good Luck

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..

I have an 03 f150 with a 5.4 engine. Truck starts and runs great when cold. Once it is warmed up is when the idle problem shows up. If I stop to run into a store or get gas and then restart the warm engine...


The symptom of which you are describing is known as "hunting"
for idle.
You need an idle air bypass solenoid, otherwise known as an IAC. The part mounts right on the throttle body. Sometimes they can be cleaned, but for around fifty dollars, I would suggest a new one.

My 2004 Prius has a rattling metallic sound on acceleration. It is coming from the top of the engine on the passenger side. Does anyone know what this can be?


Does the car make this sound when the car has just been turned off and engine is still hot? Lightly push the car back and forth while it's in park. Does it still make that sound?

Honda 1995 Engine light and D4 flashing...


Hi there;I suggest scanned the computer car in order to know additional fault codes. Check other details HERE.


The Check Engine light may come on, indicating a system problem when, in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair connections if necessary.


The Check Engine light and D4 light may light simultaneously when the self-diagnosis indicator blinks.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My D4 light is blinking. I just put in a new transmission and engine, car seems to run fine. But why is my D4 light blinking?


The blinking D4 light indicates a transmission problem. If someone installed the trans and engine for you, bring it back to them to determine what the problem is, as it should be under some type of warranty hopefully. If you did the swap yourself, I would scan for codes (free service at parts stores) to see if any come up. Last, you could try disconnecting the neg. battery cable for about 10 minutes, reconnect, which should reset the computer and the light should go off. If it comes back on, there is some kind of problem still.
