okay my car runs fine but when i come to a stop it just dies i have changed the (tfi) and the (iac) and looking to change the (tps) but i really dont know what is causing this so any info would be helpful
NEED HELP BAD!!!!! mustang keeps dying when i come to a stop
- Thread starter tugboat93
- Start date
Could be the VSS. When I first did my MAF conversion I didn't wire the VSS in it would die coming to a stop. I suppose a bad sensor could cause the same issue. Not sure though

vss ???
I guess this is a 93 gt :shrug:
I would start with cleaning the MAF sensor use the CRC MAF CLEANER

it is a 93 coupe
Vehicle Speed Sensor.
I had a similar problem with mine. i put a new IAC on bec it needed it but it was my TPS. i had a new FoMoCo sensor and it was bad so i got another one. I got the voltage right at .9 and after i did the relearning steps for the new sensor i have never had the problem again.
mine would just die sitting at a light. no matter how much throtle i gave it and it was ramdom. hope this helps

any update OP? does it have Idle roll then cut off or does it just cut off?
It could also be a vacuum leak. I've had this problem twice in the past and both times is was on a Ford. It was a different problem each time. The first time, it was on my '93 Ford Escort and it turned out to be a bad intake gasket. The 2nd time it was on my '06 Ford Freestar and it turned out to be a huge hole in a rubber vacuum line. Both repairs cost me under $10.00 (new gasket for the Escort = $5.00 and the a new hose for the Freestar ($3.00).
With the engine running (try to keep it running by working the throttle linkage underneath the hood), spray light amounts of carburetor cleaner around the intake gasket or rubber hoses to see if you can find a vacuum leak. If you feel the idle pick up and smooth out, you've found your problem. Do not spray it directly onto the exhuast system because it's flammmable.
I found both problems with this method. Also, check to see if you can hear "hissing" noises, the sure signs of a vacuum leak.
Good luck!
