Question about Ford F-150

1 Answer

Cold days 94 f-150 high rpm start

On cold days when I start my 94 f-150 up it revs up to about 2000 or higher rpms. It will calm down after about 5 minutes and run fine. Or if i give it a little gas it calms right down. When its real cold it will rev up high, check engine light will come on, idle down and sometimes stall or regain to norm. Ive heard many different problems and none really like this.

Any help is appreciated

Thanks,
Jay

    its winter again and i have yet to solve the problem. it is doing the same thing except now i start it and it will rev high w/ check engine light then stall once. then ill start it and it will rev w/ check engine light then fall then go normal. I know you said it is hard to say what it could be, but do you think it would show up on a computer engine check if i payed a shop to do it? and do you have any suggestions of how to find out what it is.?

Probably is a emissions sensor problem, lots of these parts are plastic. check out the throttle cables, lub em wd40. there is a type of valve somewhere on top of engine, it may be cracked, pcv valve stuck. lots of possibilities, almost too much for solution online. something emmissions with an electronic sensor is acting up.

92 chevy idles real fast on cold start up, then after run warming up runs fine


Not an uncommon issue for one to idle fast while cold but , 2000 rpms is a little higher than normal. May want to check the engine coolant temperature sensor for proper voltage and the coolant level. Also, check for small vacuum leaks around the throttle body gasket.

My 2004 mondeo 1.8 16 v is playin up firstly when you start it up revs are on 1500 revs but then calms down to just under 1000 revs and when youd accelarate car just wants to slow down and also steering...


starting on very cold mornings ,the engine will run at high rpms (just like you have a choke on) and then will after a minute or two return to idle rpms( most cars is around 850-900)
If you have a hydraulic clutch and you have never changed the fluid then I suggest that you have it done as the fluid is probably freezing the water content in it ( brake fluid is hygroscopic-- attracts moisture from the air)
Check the linkage adjustments for dirt and other foreign objects stopping full movement or if the lever is direct into the top of the box then check the gear lever pivot at the top of the box for loose or adjustment.
If you have a cable clutch ,consider replacing the cable.

My 96 ford taurus revs high when starting then works it way from 1500 or more down to 800 but fluctuates from 800 to a little over 1000. When putting car in rverse or drive from park engine revs up to...


You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?

I have a 97 s10 and starts and runs fine when cold but after it warms up i have to hold the gas peddle down to the mat before it will start again and when it does start it revs up to 1 1/2 to 3000 rpms and...


The repair for this is to scan the computer and see what codes are present if their are no codes indicating the TPS switch the problem will be your fuel pressure regulator.This is a fairly big job it requires removing the intake manifold if this is the 4.3L vortec engine.But Iam not sure which engine you have so this applies only to the Vortec Engine.

My toyota randomly will rev up the rpms to about


your idle position sensor could be bad. if it reads incorrectly, then it can randomly adjust to a higher idle like when you cold crank and let it warm up.

1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle


ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week
