High Idle Speed issue (Pacifica 2005 3.5L)
Hi to all! I urgently need your help. I replaced the spark plugs on my Chrysler Pacifica 2005 3.5 L. After that, I tried to start the car. It started up but with very high idle speed. After a couple of seconds, the car turned itself off. Every time I start the car, this problem repeats. All hoses checked and bolts spun. Any idea? Maybe I damaged the sensors?
Thanks a lot in advance Alex |
There is a Mass Airflow Sensor mounted on the black rubber air intake tube. It can be easily damaged (or left out) when doing the plugs on a 3.5. Can you verify MAF sensor is in place and functional?

but I figured out that U have a bad vacuum leak where egr tube goes into upper intake... missing gasket. https://cimg4.ibsrv.net/gimg/www.chr...905693d4f.jpeg |

Yes, the missing EGR gasket could do it. Either that or the MAF sensor leaking vacuum, causing the engine to rev up...

Not sure at this point. May try a good scan tool to see it it is throwing any codes...

OEM plugs or an alternative?
