I have 1994 ford rager that is having a problem it starts fine and
every time it has 195000 miles on but if i do not keep my foot lightly
on the gas it will run really ruff and die. If i drive it is fine but
when coming to a stop if i do not run it through the gears and rev it
to a stop it will start to die uppon giving it gas to keep it runing
it will some times kinda of back fire but not a back fire more like it
is trying to clean out an old 2 stroke motorcycle then runs fine. Some
time if i dont not stop it from stalling it will take some time to
start and have the rev it up and clean it out problem then run fine. I
have Changed the ing. coils, spark plugs and cleaned the Idle air
control. Need some help have to smog the truck and know it will not
pass Please help!

Have you put it on a code reader?

You might want to check the Mass Airflow sensor.

My truck starts fine but if I don't keep my foot lightly on the gas
it will run rough and die. It drives fine but when coming to a stop
it will start to die unless I rev it up to keep it running. Sometimes
it kind of backfires, not a normal backfire: more like it is trying to
clean out an old 2 stroke motorcycle, then it runs fine. Sometimes
if I let it stall out it will take some time to restart. I have changed
coils and plugs and cleaned the Idle Air Control. Please help!

It sounds like a bad IAC. My 92 Buick had the same symptoms.
The IAC looked good, and I cleaned it and cleaned its seat in the
throttle body. No help. So I bought a new IAC and installed it.
It has run perfectly for a year so far.

Good luck.

Rodan.
