Question about 2005 Chrysler Pacifica

1 Answer

Acceleration won't go past 3000 PRM at idle

I have a 2005 Pacifica (3.5L). The car has been idling rough at times and I noticed that with the car in park (at idle), if you try and rev/race the engine it will not go above 3000 RPM. The car runs great on the road, can redline the RPM accerlating from a stop. I thought it may be the Mass Airflow Sensor, but I was informed at Autozone that this car doesn't have one. Has anyone seen this problem before?

The car does have a maf, but it is rarely the cause of rough idle. Rough idle is usually caused by vacuum leak, pvc issues, or idle air control valve. What does it do, specifically, and is the engine light on?

SOURCE: 05 pacifica. 3.5 the engine

These are the crankshaft/camshaft sensors tyhat directly relate to the problem, using a cheaper version hand scanner will not detect which of these are defective you need to have the system's values read out by means of a quite expensive OBDII scanner generally found in a repair shop or Dealership, the p0016 code(Cam/Crankshaft Pos. Correlation SensorA-Bank 1) you have read from the hand scanner is a good start but not for a good finish... I have one too but can't afford to have the $5,000 monster and 5k is just about where they begin in price for anything decent.
Typically the crank sensor is the common sensor to fail but it can be either/or....I don't believe your compression is at fault as you stated the engine runs fine until over 3K.
Take it to a reputable shop and pay the diagnostic time it will save you a lot in the end.

SOURCE: Why doesn't my car stay started?

try giving it a little fuel to keep it going. if it still goes but will shakes and splutters and coughs before smoothing out it sounds like fuel is draining back from your engine to the tank. if you have an electric fuel primer pump that turns on when you turn the ignition to on you should be able to hear an electric whine unless your car either does not feature one or its not audiable/ possibly not working. leave your car at "on" for 10 seconds then try starting it as well. see if it improves

Had a question bout my mazda rx8 I was driving it one night it was running fine the next day went out and it won't turn over it takes awhile bit it finally starts and idles real rough and you give it...


Too many possibilities

Won't turn over is one problem -battery,cables,grounds,
starter,solenoid,etc

Idles rough-- vacuum leaks,spark plugs never replaced,
egr valve etc

Worn O2 Sensors
Dirty MAF Sensor
Old Fuel Filter

You have to go into a lot of technical detail & history
on your vehicle, for us to even guess.

What causes my ford escape to rough idle occasionally?


Could be a fault in the Evap system (a loose/defective gas-cap), water in the fuel, defective I.A.C. is possible.
When the rough idle issue occurs does the engine light come on?
