Suddenly, my car is stalling, not always, but now and then. If it stalls, it is when maneuvering around a parking lot, or backing out in the morning. It always starts right back up, and shows no sign of a stall when driving, and it will not stall when stopping at a light.
Here are the facts:
Over the last few months, my car was having trouble starting so I replaced all the little things up front. New Ford throttle body with new IAC and TPS which come with the unit. Remanufactured: Mass Air Sensor and Distributor with Stator. New K&N (actually a million mile warranty free replacement)...and when I put the new K&N filter on, I found that I had a crack in the plastic housing of the MAF, so I was running my engine pretty dirty because the intake was by-passing the K&N and sucking air direct from the engine bay with no filter. I am sure that is what blew up my IAC.
I also put new wires, plugs, coil, and new O2's...ummmm....I guess that is about it. When I found the air leak in the MAF, I sprayed a can of throttle body cleaner into the intake (while the engine was running) and it would drain back out pretty black, so it was pretty dirty.
After replacing the MAS and the stator, my car would fire up very nicely in the morning. The rpm's would start at about 1100, but then quickly bounce down, as in 900, back to 1100, down to 800, back to 1000, etc, until it would finally settle at about 700 or so. When it idle's at 700, and crawling around in a parking lot or leaving my driveway, that is where the engine will putter down to 400, maybe bounce back up, and sometimes stall.
I ran codes, weeks ago, that is where I found the bad MAS and stator. But I have not run any codes today.
So, what give?......are my injector's clogged up?....is there a vacuum leak?....if I run the codes, will it tell me about a vacuum leak or clogged injectors. As best I can tell, I have plenty of fuel pump, but who know's?
Any thoughts would be appreciated.
