Car Stalls Randomly While Being Driven

Car stalling.

How many miles on the vehicle. Maybe check the IAC, cause it can get pretty dirty over time. Or your vss could be acting up.

IAC

pull the IAC and clean it out with brake clean and also set the TPS sensor to .98 and set timing to 14 degrees after all that do a tune up cap rotor wires, plugs also clean the MAF meter sensor wire with carb cleaner by sprying it about a foot away from the wire after all that it should run like a champ

Could be the IAC or it could be the TFI module. Run codes and see if any pop up then go from there.

Dump the codes and see what the computer says is wrong…

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great.

IF your car is an 86-88 stang, you'll have to use the test lamp or voltmeter method. There is no functional check engine light on the 86-88's except possibly the Cali Mass Air cars.

Codes have different answers if the engine is running from the answers that it has when the engine isn't running. It helps a lot to know if you had the engine running when you ran the test.

Trouble codes are either 2 digit or 3 digit, there are no cars that use both 2 digit codes and 3 digit codes.

For those who are intimidated by all the wires & connections, see http://www.actron.com/product_detail.php?pid=16153 for what a typical hand scanner looks like. Normal retail price is about $30 or so at AutoZone or Walmart.

Check out the EGR too. I had a similar problem recently, and I took out the vacuum, plugged it, and it runs perfect now.

Threfty how did u go about taking the vacum away.. i think i have the same prob..
