Problem stalling


New Member
I have a problem with the car stalling. It only does it after cruising on the highway for awhile. Ill be driving fine in the highway, Ill come off the exit ramp to a stop and it will idle fine. I go to take off, and the car will stall. Has happened 4 times already. Pretty scary actually. Ill bring the car to a stop, put it park, start it, and it will run fine the rest of the time. Like I said it only happens after driving on the highway for awhile. I have done a full tune up, fixed some vacuum issues, changed fuel filter, hot wired fuel pump. Had the coil pack checked, that passed. Im at a loss. This stinks. Any help would be great. Thanks in advance.

Does it stall if you put it in neutral just before you stop? If that fixes it, it might be the TCC solenoid/TCC pedal switch.

Take a look at the TPS setting, and maybe the EGR valve is stuck slightly open.
If it isn't the TCC being messed up then I would look at the O2's on the scanmaster when it happens/while it is happening.

Or a wideband sensor display if you have one. :cool:

If the display is 000 or something like 030 etc. for a few frames of data you would be lean when it's happening if its in the 800's you would be rich.

Checking your just off idle response ie. light throttle off a stop sign while driving the car, not in the driveway, might also show a lean or rich condition even if it's not stalling on the scanmaster.

Worth a look, and if you don't have one or direct scan or turbolink diagnostic tools it's time to get one of the three. :)
One more thing I forgot. If I drop the car down to dive instead of overdrive, the car will not stall out. Thanks in advance.
