Engine runs really hot, and engine light comes on while in D4
Engine runs really hot sometimes, and when i put it in park the idles back and forth but this only happened once and when i drive in D4 check engine light comes on 1/2 of the time but in D3 it gets really hot
Re: Engine runs really hot, and engine light comes on...
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

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..
The symptom of which you are describing is known as "hunting"
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.
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.
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.
