SOURCE: 1987 F 150 Problem: engine idle stalling and then surges

I had the same symptoms on my 1993 F-150. A friend of mine commented that he could smell gas in the exhaust. Eventually, it got to where it would start, then die after a few minutes and wouldn't restart after that (at least for several hours). It turned out to be a bad fuel pressure regulator that was causing it to flood. It was about a $25 part and an hour labor to replace (not difficult, just awkward getting to the hex head bolts).

SOURCE: low rpm's in idle when heating/cooling system is on & surges.

Check your EGR or your Idle control Valve. This can cause a problem with your irratic idling

SOURCE: My 1993 Escort with 1.9L engine surges at idle

Change EGR valve and EFPV(or evp) sensor. Both control idle.

SOURCE: engine idle speed

Sounds like you idle air control valve is starting to mess up. You can actually take this off and clean it with throttle body cleaner and it should help get your idle back to normal. As is sounds the idle air control valve controls how fast/slow your car idles. It is located on the throttle body normally held on with a couple of screws. The throttle body is where the air duct hose coming from the air filter box ends at the engine block. Here is a picture of what you are looking for: a483326.jpg
Make sure that you clean the valve portion and not the electrical plug with the throttle body cleaner. Let it air dry or blow lightly with compressed air before putting it back on. Let me know if you have any more questions. Thanks for using FixYa!

SOURCE: The engine boggs down at high rpm. For instance,

if the fuel filter hasn't been changed do so, if the fuel filter is ok and has been changed out due to this problem you will need to monitor the fuel pressure under a load and make sure it doesn't drop below 45 PSI, it it does you will need to replace the fuel pump and the fuel filter. U also do say if you have a check engine light or have had the system tested for trouble codes that may be triggered by this loss of power problem.

2008 ford ranger 2.5, what could be the problem if engine starts normal but after second the engine fluctuate?


Bleeding the fuel system is typically only needed on high pressure systems like GDI and Diesel vehicles, and only to get them to start if they run dry once.
If your engine keeps running but the idle speed moves up and down there are many things that can cause that. More information is always helpful. Does it always do it whenever the car is running? Or does it only do it conditionally (IE Only when 1st started in the morning, only after warmed up or getting off the dreeway, only with AC on or at night...describe as much as you can.)
Most newer cars have computer controlled idle strategy that wants to idle the car cold around 1000-1500 rpm (After an initial higher rev called a FLARE) and then bring it down in 3 or 4 minutes to 700ish rpm. If it CANNOT bring it down by normal means, then many resort to something called FUEL CUT IDLE where it actually turns off the fuel momentarily and the RPM will drop because the car is stalling and running out of gas...then back on and it starts to rev back up and when it gets too hiugh it turns back off. Cars that do this can have annoying surges from 500-2000 back and forth at idle forever.

a vacuum leak or MAF meter problem can cause rough idle. ALmost any engine code that turns on CHECK ENGINE lamp may be suspect, does it have any current fault codes?

As well, consider Sticking manifold runners, EGR systems, and temperature sensors all can cause surging, so can a defective Oxygen sensor, slightly jumped timing, and dirty throttle plates the ECM wants to close more but they wont due to dirt. If its not something fairly obvious, it may require deeper checking.

I have 2002 audit quattro TT with 180k miles. When I do a normal acceleration the car surges and rpm drop but pick back up. If I accel hard it runs fine. Also at idle at times it varies 200 rpm like a


this sounds similar to a problem i had. as the rpm went over 2000 the engine would stop for a split second and then kick back in.
after a few days looking my garage finally found the problem was a faulty air mass meter.
this cost me £200 in total to be repaired.

Eng. rpm not dropping when clutching & at idle, rpms go up & down


Here are a couple things to try. The idle surge is a common problem. Ford makes an adjustable plate like the one below. It allows come control over your idle. I made one and it eliminated most of the surging. I think the Ford part is about $30. Can't seem to find the ford part number though. Search online.

http://k-mansparts.com/items/performance/ford-mustang-iac-adjustable-idle-spacer-kit-50-46-f2pz9f939a-detail.htm

Try www.fordfuelinjection.com or other ford sites. Lots of great information.
My 89 seems to roar loud when cold when coming back down to idle and I am sure its the fan clutch. I have also heard the water temp sensor can cause idle problems because the EEC does not know what state the engine is in. (hot/cold, etc)
Hope this helps. I do recommend the adjustable plate though.

1989 EscortTac shows surges in RPM, but engine does not race up.


How many miles, has the timing belt ever been changed? (60,000-70,000 miles) when the belt gets near or over it's recommended change mileage it will get loose and cause the engine to run like it has a miss, mostly when cold, also u may need to do the following procedure, Escorts need this more than most other Ford cars
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
