Took my car on a road trip today and things did not go as planned
. Well into the trip the car would hesitate and begin to stall at highway speeds if I gave it gas too quickly....and by quickly I mean normal....not like I was trying to go WOT. Every time this happened I would have to pull over to side of road and once I slowed down to around 10mph RPMs would drop to 500 and car would completely stall and shut off.
This happened at least 5 times and each time the car would start right up again, but after a bit it would repeat. If I was in a position to have car towed and find alternative I would have, but this was work trip and time was of the essence so I soldiered on with the car.
I'll preface all of this by stating that the car has had a freaking ton done to where it "should" run like new but it seems every time I turn around something else is wrong with this damn car.
Things done in last 2 years for maintenance:
- New IAC
- NEW MAF sensor and adapter
- New Purge Valve solendoid and adapter and connecting hoses
- New plugs and wires
- Fuel system cleaning
- New Oil pan adapter gasket
- New Head gaskets
- New vaccuum hoses
- New O2 sensors (all 4)
- All new fluids (coolant, power steering, etc.)
That's everything engine, intake, and fuel system related I can thing of that's been done.
The only code the car is throwing right now is P1445 which is the damn purge valve system that shop rebuilt once already this past summer. I don't believe they changed the actual canister and read "maybe" that could be cause???
Other potential culprits I've read are:
- bad fuel pressure regulator
- fuel pump on its way out
- bad MAF (but that "should" throw it's own code)
I am taking the car back to shop soon to have warranty work done on purge valve system they took care of to get code fixed. Hoping that fixes stalling issue as well I described above.
Anybody else had their car behave this way? Note, I've been driving locally and been up to around 50mph consistently with no problems. Was not until highway speeds it started flaking out on me.
