88 f150 351w forever to start and when it does it runs real rough until I hold gas down for a minute then idle rough but will start right back up unless it sits awhile doesnt want to start back up


There are several possibilities for this problem. A "cold start" sequence is suppose to activate based on water temperature and the signal from the water temperature sensor. This makes the fuel rich and adjusts timing to make the engine run better when cold. It works like a choke only it is electronic.

There may be 2 sensors with one making the dash gauges work and the other doing the engine controls. If not 2, then 1 sensor would do the whole job.

Another possibility is an air leak in the fuel system which makes the system bleed dry overnight. It is far less common on gas engines but happens a lot on diesels.

Some earlier Ford engines from 1984 to I don't know when they stopped on trucks, would use a step-up solenoid on the accelerator bracket that worked off water temperature. Sometimes a bad water thermostat would make the temperature controls malfunction the other way (High idle, clicking, low idle) that would stall and engine as the temperature vary.

High low idle, rough idle stalling


If it's surging, make sure your radiator is full. Do a tune up, plugs, wires, etc. Put some fuel injector cleaner in your fuel tank. On a cold start the vehicle compensates for being cold by adding fuel. Once it warms up the computer tells it to quit adding extra fuel. If it is a bad sensor of sorts, check engine light should come on.

My 1999 Ford Explorer XLT has started stalling while driving down the road. Sometimes it will start right back up and run fine, other times it will run for a minute or two and then stall again. Sometimes...


couple of things,if you a autozone ,pepboys or another automotive store around they can diagnose it for free,or you may want to check your idle air control valve aslo known as iacv its on your intake manifold close to your carb it could be clogged up with carbon from burned fuel build up.good luck

I am guessing here w/o much info, 1 of maybe 4 things, idle speed contoller motor, low fuel pressure, dirty air filter, or lastly, carbon buildup on the throttle body throat. When cold idle the carbon blocks off the little needed air and the engines will run rough or just die.

2002ford truck explorer when i frist start my truck it will stall out a few times then wiil run good for awhile then for some reason stall out 3 or 4 times some times i can drive for 150 miles with no...


it sounds to me that you idle controll valve isnt responding (could be dirty) get a can of carb cleaner and clean the thottle body inside and with the engine running. squirt just a little and the engine will start to stall and the idle air controll will start to open ( you will hear it start sucking) then spray more in sperts try to keep the engine running at idle . this will make the engine RPM's change and open and close the idle controll valve thus cleaning it. when done save some carb spray. put the air cleaner hose back on. and start the engine and with the engine idling spray around the intake and base of throttle body if the rpms change you have a vaccume leak than will need to be repaired.
good luck
