Ok i start the car and it either does one thing or the other. It starts fine and then as i drive the rpms drop while driving or when i first come to a stop, and it acts as if the car is goin to die. But then it gets back to normal and car usually drives fine after that. What could it be that makes the rpms just drop and seem if the cars is just goin to putt out...thanks

 

I would say alternator

 

My alt is pretty new and none of the power dies just the rpms drop..

 

If it runs fine then I would say tach is bad.

 

Clean your throttle body, go to --> www.motorvate.ca for a write up.

 

Are you saying that when you are coming to a stop or slowing down that when you apply your brakes, the RPMs drop almost to zero then come back up? I had this problem a while back. All I did was clean the throttle body and it cleared right up. Hope this helps.

 

yeah i would start with the throttle body

 

hey thanks for the responces, yea when i come to a stop the rpms will just drop and it sounds like the car is gonna die. Also if i just get into drive like it sometimes dies out like i get stuck in a gear...

 

yeah just make sure you gets some throtlle body cleaner, and cleaner it really good with a toothbrush

 

If that does'nt help try the EGR system.

 

And check the PCV valve.

 

Aux air idle control, TB, vacuum leak, maf, needs tune up, dirty fuel filter,egr stuck.................

 

try replacing fuel filter

 

Hi two more questions, i have pr cai now what problems could arise from a dirty filter and you know the little whole on the upper tube for the air sensor i belive. Well my sensor never fit well so i got it like taped on, if particles get in threw there what troublems might that cause. thanks

 

how much would a new filter cost also and how could i tell if new one is needed...thanks

 

most filters cost like 25$ but u can prob use hte k&n filter cleaner on it also most cone filters are supposed to be cleaned after 35k+ miles

 

try checking the fuel injectors, it sounds like your fuel air mixture is bad. could be fuel/air mixture or deposits in the injectors. maybe you have a loose vacuum line or a clog in the the lines, perhaps your mass air flow sensor??? try a fuel injection cleaning solution. whatever you do, try to eliminate the most expensive things by checking lines and such.....

 

does your car have a power brake booster ? that are usely the symptoms of a power booster going out . as soon as you apply the brakes it suck some vacuum from the manifold and the car starts dying.
