My 79 ford truck has a rough idle in drive,is this

Fuel filter. Low fuel no power. Catalytic converter. no air out, no air in. loss of power.

Turn in the idle speed screw on the carburetor throttle-raise the idle some, it will open the throttle plate a bit when you turn the screw in. Idle speed should be about 800 rpm's, with truck in drive, foot on brake, and engine at normal operating temperature. If it still dies with the idle raised, it might need a tune-up-plugs, wires, dist. cap and rotor, and new filters. Good luck.

there is several problems with this model..call to discuss,985-248-2726

If your Escape is v-6 powered a common problem believe it or not is a solenoid in the transmission that allows the torque converter to "unlock" at idle. If the solenoid is bad then the torque converter stays locked and puts a load on the engine causing rough idle in gear at stop.

could be the map or the egr valve, or a vacuum leak, get it installed on a real time scanner not a code scanner,

You will need brakets from a F-100/150 73-79 2wd 302 engine then the windsor will bolt up.

idle air control valve needs replaced loaded up with carbon

I Have a 1999 ford f150 4.6 that back fires and is just running really ruff when idling alot of nack fire a sord of like a pulse going on what is my problem?

fuel filter and tune-up

listen for a vaccum leak.also try disconecting bat for 5 min the reconnect and start truck and hold idle at 1500-2000 for 5 min. this resets and teaches computer to self adjust
