SOURCE: starts and stalls

I had a similar problem on my 1999 Grand Prix, 3.8l engine. I replaced the IAC Motor (Idle Air Control) that attaches into the throttle body. After disconnecting the battery, the computer goes into a learning process. It stalled once, but now seems to be running correctly. The codes set were Engine Misfire, which could be anything. I also bought a crank sensor, which is suspect, but I didn't install it.

Car wont stay running unless foot is on the gas pedal


is the CEL check engine light out running? (it comes on stalled, and is normal that)
stalled. engine stall. no year, now that makes this 10x impossible
and even more impossible no engine stated, (displacement or VIN)
F22? 2.3. 2.7? 3.0L?
if in usa, (no loctation stated ) open hood, look up, see tag?
see vacuum EPA map, see engine type? bingo.

so I wall answer in the generic, (ALL CARS gasoline)
fails hot or cold engine, does hot engine reach 180F and hold?
wow, how low was the oil, off end of stick, none?
stalling is caused by over 50+ things. (we do tests to find it fast )
we use tools, do you have tools, or can buy them, or do you just want
endless guessing. here is the path.
#1 stall maker is a stuck open EGR main valve, ignored during the turn up, clean it. make sure it close
in the macro,
1: bad engine, the hot engine can lose compression and stall.
tool1 the $20buck compression guage.
2: bad spark, or timed wrong. gapped plugs wrong, wrong plugs used. bad wires sets, (old dizzy engines) bad COPS newer cars.
check for hot spark at all spark plugs, skip none.
3: bad fueling (too much or not enough
if engine runs perfect and only idle is too low 800 hot is normal
no DTC 300s misfires, then maybe the ISC is just dirty.
we clean the EGR and ISC every time.
if the EGR leaks, the fast right foot can save a stall but is hard.
if the ISC sticks closed, saving the stall is piece of cake, super easy
after all , you are adding the missing air.

does that help,. no, then take it top the man, the ASE man.
The Mechanic.with the ASE patch on his /her sleeve.
no year, ouch.

2005 Dodge grand caravan stick gas pedal


Inspect the cable to the throttle control mechanism under the hood? All all the cables in their proper tracks? Are any cables wrapped the wrong direction, or out of the in-line track?

these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.

ENGINE STALLS WHEN I STEP ON GAS PEDAL


Sounds like your fuel pump is going bad! The more you press on the pedal the more demand is on the pump and it cant keep up cuz its junk. Try to limp it to a shop to replace it, unless u wanna do that yourself.....
