OK, to be fighting the P0174 code. As stated in an earlier short article I replaced the fell down hose with the latest/greatest piece from the dealer. Difficulty solved; however, ns still get an sometimes P0174 every few weeks and on top of that I have actually occassional difficult cold starting. I changed the IAC unit through a new one (Napa Echlin), the cold start worry seemed to be solved, yet sporadically it still takes lots of cranking at cold start, yesterday no issues, but Thursday 2 or 3 time at 7 - 10 seconds of cranking prior to it fired. When started, restarts during the day seem fine. In trying to find vac leaks with carb cleaner, I found none; however, ns realized the the PCV valve itself is loose on the earlier side that the engine. Is this normal, that seems choose it twists right into place, probably its broke and also giving me a vac leak and also occassional hard start? do I have to remove manifold come replace? Either means need some thoughts ~ above this together I dislike to take it it to a shop for something stupid, yet I need it to run as I require to move daughters to school.... Thanks for any help, Mike.

If PCV is stuck open it will influence cold start. If you eliminate PCV you deserve to test by blow low pressure air v it. Waiting should circulation easy in one direction and also should not flow in other.1989 MPV 3.0L V6 2WD

The PCV hose device tends to acquire stiff and loosened with age, and developing splits. Ns would indicate you use a mirrow and good flashlight and inspect the whole system ... Specifically on the firewall side. You deserve to use part RTV to assist seal increase some connections of water tap to metal.

When I had the intake off on my wife"s 2002, ns tried using long needle pliers come unscrew the PCV. It was "welded" with warmth so tight, i was fear to break it. After checking its operation, ns left the old one alone and also just replaced the hose.2002 Mazda MPV LX1967 Camaro RS1994 dodge 2500 5.9L Cummins
