I am lost! I’m hoping someone here can see what I haven’t.
I did an engine swap for my 2004 Chrysler Pacifica 3.5L V6 engine a few weeks ago and everything went great. I drove it for about 2 days and it drove fantastic. The engine had real power to it etc.
The old engine had 160K Miles on it. The new one I bought from a great company on eBay had 81K miles on it. The engine looked great and it is in an amazing shape. Here is what’s going on.
I was driving in the city after 2 or 3 days with the new engine and it started shaking pretty badly and I immediately pulled over to the side and shut it down. I had it towed to my driveway.
I used my OBDII scanner and I saw the P0172 code and the engine smelled like gas. Took the dip stick out and it also smelled like gas as well. No notice of milky pattern of a blown head gasket (This is not the case because the car doesn’t display the symptoms).
When I took the intake manifold out, it was full of gas near the throttle body and it was a lot of it. I cleaned it out and put everything back together and the engine started immediately. It flooded with gas again. I know that the code suggests the following possible causes:
- The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of “oiled” air filters can cause the MAF to become dirty if the filter is over-oiled.
- There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
- There could be a vacuum leak.
- There could be a fuel pressure or delivery problem
The battery Keeps dying (It’s a new battery not even 2 weeks old) and whenever I charge it or get a jump from my other car it cranks but won’t start.
I did change the engine fuel injectors to my new ones since they are 5 months old only and a good brand. I tested them out and they all have the same resistance. Also, when the engine was running there is a RAPID clicking sound coming from the engine.
Could it be a stuck fuel injector? No mechanic would touch it and it’s been sitting in my driveway for a few weeks now. I will give a great tip to whoever help me figure this problem out. Thanks
