"My" 1995 F-150 Idles. Maybe "your" F150 has a vacuum leak, causing it to idel instead. This condition would cause it to suck for sure. Try looking for a hose off someplace, and maybe a cracked or otherwise broken fitting. If you can get someone else to help, try locating the leak by sound while the other person operates the throttle.
Probably valve stem seals.
Could be a Throttle Position Sensor.
The engine has a serious ignition or injection problem needing repair
because it is not warmed up enough to stay running or you have the idle speed down too low and it not running at the right rpm to get the transmission up to speed
I unplugged air censor under hood on top right side engine flat black box to see if that was the problem and it was
i hate to tell you this but the stock carbs are just junk. you are better off just to go after market. weber or sidedraft. It will fix all your problems. $300 fix.
check the catalytic converter.Sounds like it is possibly plugged.
Change the fuel filter before you go any further.
have you checked your spark plugs? Orrrr... vacuum leaks, computer connections, wiring, fault codes, CTS-coolant temp. sensor, valve timing, etc. Bring it to a garage.
Sounds like mass air sensor is out. is it burnung exsess fuel? if so sensor is bad. Also check knock sensor on side of block. for some reason the threads losen and will back out on it's own. This will cause rough and high idle and bad shift points. Hope this helps.
Spark plug wires? Coil pack? Dirty injector? Spark plug wires? Coil pack? Dirty injector? Spark plug wires? Coil pack? Dirty injector?
