Car sat for 2 years, does not run at idle in park unless you hit the accelerator the whole time.... occasionally backfires. Once the engine warms up, you can idle it in park, but not Drive/Reverse. Vehicle stalls at every redlight, or when driving less than 10 mph. I basically have to be holding my foot on the gas when i shift from neutral to drive, or it will stall. P0300, p0301, p0302 are the codes it runs. never 0303 or 04.
Hi Cody:
I'd be checking all of the vacuum hoses and the PVC valve.
Also it wouldn't hurt to put some fuel conditioner like SEAFOAM through it.
My approach tends to be to make sure the basics are looked after before starting to second guess for major problems.
Cheers.
I've used injector cleaner, and replaced the spark plugs... no apparent vacuum leaks.
Hi Cody:
2 more suggestions then,
1) Take it out for a good long drive, and don't be overly gentle on the throttle. Sometimes it takes a while tfor the engine to get used to running again.
2) History - Review how it had been running prior to the 2 year vacation.
Might be an idea to pull the PVC valve and clean it. Make sure it rattles and is not gummed up.
Pvc is stuck closed...sprayed brake cleaner through it... no fluid came out the other side
"AHA" he said.
Could be the clue you're looking for.
Stuck open would result in a vacuum leak which would cause lean mixture at idle, resulting in engine stop.
There should be a high vacuum at idle, which would draw crankcase vapour in through the PVC. Stuck closed at idle may be resulting in too rich a mixture.
When you changed the plugs, were they sooty fouled (too rich) or dry & "burnt" (too lean)?
What happens to your idle when you disconnect the PCV valve?
Time to play detective!
