I've been having a problem with my car stalling when I brake. It only seems to happen when it's warm outside and I have been running errands and stop for brief periods of time. After about the third stop the car will stall and I have to keep restarting it and keep my foot on the gas. My mechanic seems to think it's the IAC valve. I'm not convinced based on what I've read.
View 7 RepliesI have a 2001 Ford Escape, and when I start it for the first time of the day, it idles really rough, and way below 500RPMs (to the point where it almost stalls). After about 10 minutes, when the car is all warmed up, it runs smoothly, as if there was nothing wrong with it. The only conclusion I can draw is that it is temperature related, but I can't figure out exactly what is causing the issue. This happens on the driest or wettest of days, so moisture doesn't seem to be an issue.
View 2 RepliesThe check engine light came on yesterday. 2004 with 115K. Auto Zone read the codes and they are as follows:
Definition:
Idle Air Control Valve control circuit.
Probable Cause:
Open or short circuit condition.
Poor Electrical Connection
Failed IAC motor
Posted earlier with my escape randomly stalling at idle. Getting a code po446 along with po511. Only stalls at idle after warming up and letting it set a while. When you go to recrank it that is when it won't idle or if it does its at 500 rpms or less. Also after driving it today it smells like rotten eggs. Replaced the idle control valve with no luck. What could cause this?

View 2 RepliesI'm removing my idle control valve to clean it. Everything went well until I'm at the last T40 bolt holding it. I go to insert my T40 bolt it doesn't seem to go in. So I'm like oh I guess it was switched to a smaller T so I put a T30 and it's to loose so I'm like aww cmon. Here are 2 pictures (not the best I know) of the bolt in question.
Is it actually stripped or it's some kind of other bolt? I tried a allen but it seems to slip to. If the bolt is stripped.
After its 2.3 liter engine is warmed up, our '87 Ranger has intermittent problems of idle dropping to nearly dying altogether and then overcompensating to recover. Normally, after throttling up to 1500rpm or so, it will idle steady for 15 or 20 seconds then start the process again.
After normal tuneup part replacements (i.e. plugs, wires, cap, rotor and fuel filters=there are 2), I spent over $100 on replacing O2, throttle position and EGR sensors but symptoms still occur. Was advised to consider replacing the Mass Air Flow sensor but that part doesn't exist for the '87 model. Was told the equivalent part is "Idle Air Control Valve" at approximately $80.
My dodge neon started to accelerate by its self and stays accelerated. My brakes can barely stop it. The check engine light is on. And it says it is a pinched solenoid sensor for the emissions. But to my knowledge that won't cause my car to accelerate like crazy and remain accelerated to 40mp and remains there.
I did some research and i keep coming up with IAC valve (Idle Air Control Valve). Not sure if this is the problem. There could be numerous problems. I am replacing IAC valve this week.
I have been getting a buzzing sound under my hood, usually in cold weather that lasts a few seconds, happens after I go about 1-2 miles from my house, did online research and it might be my IAC valve getting internally dirty.
Could replace it for $50.00, some You Tube videos show people cleaning theirs on other brands of cars, can the Ford IAC valve be cleaned up with a little carb cleaner and cotton swabs?
My wife has a stock 03 Passat 1.8t.
1. The car seems to shift too soon from 2nd to 3rd and i can hear the turbo drop pressure. It sounds like a quiet blow off 3 or 4 times when it shifts from 2nd to 3rd.
2. There is a vacuum control valve that sits on top of the air cleaner box and it ticks a lot. it has a electric plug going to it.
3. The car has a rough idle while in drive and sometimes shifts hard. I changed plugs, trans flush and filter change.
I would take the car to a VW dealer but the closest one is about a hour away and my wife needs the car.
For the past month or so, my 2002 Kia Sedona has been stalling/dying whenever I stop at lights or signs. We've gotten the alternator fixed, gotten a new battery, replaced the ignition coils, but still have the same problem. A friend of mine says that there is probably an issue with the idle air control valve and suggests I replace it. Looking online, it seems like I can possibly just clean it out, but I don't know where to begin. Where exactly is the IAC valve and is replacing/cleaning it a basic DIY job?
View 8 RepliesThis happened on the way to church Sunday morning. Got in cranked up and headed out. Car would not accelerate beyond 40mph and would not shift gears. Drove like this for a few miles and as some others have stated......there sounded like an explosion and then whistling and spewing of air. I pulled over think it was a a radiator or hose issue. Didn't know anything about an EGR valve.....NOT a mechanic. Drove the car back home. Like others have stated......after it blew.....then the car drove just fine. Daughters boyfriend identified the problem.
Bought a new valve and installed. Got out on the highway and had exactly the same problem .......would not accelerate beyond 40 or change gears. Then within 3 miles the EGR valve blew again and then the car drove fine. Needless to say I will NOT be putting on another valve....as that's not my core problem.I was wondering if any of the other Escape owners had determined the cause of the blown valves? At this point, I'm just hoping I can last long enough to buy another car. But I would like to know what type of issue I'm dealing with.
I will try to make this short but still involve all necessary information. I was driving on the highway last Wednesday when my cruise control went out and i couldnt drive over 25-30 mph, my check engine light did not come on when this happened. I managed to limp the car very slowly about 2 miles down the highway as that was the nearest exit. I took the exit and when i went to "accelerate" at the light i got a loud whooshing sound from under the hood. I pulled into an auto repair shop and found the EGR Valve had a hole blown in side.
Several hundred dollars and several hours later the shop put on a new EGR Valve and had cut the lower cat converter of the car and run a straight pipe where it had been. They said they believed the cat got clogged and built up enough pressure to blow the side out of the EGR. The car ran fine like this for a few days while i waited on my brother in law to gut the cat so we could replace the cat shell as to be within the law, as it is illegal where i live to remove the cat. We gutted the cat and cut out the section it was originally and put the shell back on. The car ran ok for a few hours but then i stopped at a gas station and the check engine light started to blink and the rpms would run way low. When i say low i mean around 1000 at 55mph and would idle around 250, if i put the car in neutral it would idle around 500 but that is still low. What i could look into as the cause of this issue?
My wife drives a 2008 V6, where is the PCV Valve? Pics ????

"CODE P0443 canister purge fault" diagnosed....
Found: EVAP PURGE FLOW VALVE STICKING
Recommending: "Diag, Replace sensor then retest" ....
They want to install a new 9C915 which they called in hand writing a Canister purge sensor but I've seen it called a canister purge valve on another thread by FIREME who puts 9C915 as "toward the driver's headlight assembly, near the radiator. You'll need an 8mm socket to remove it"...

From the "newly washed ashore" who's now double posting after being flogged for trying to keep this info in a single thread rather than spreading it all over the place...
I have a 2001 ford escape v6 the engine light is on and when advance pulled a code it came back egr valve is sticking and #2 is not firing.. I have a 2002 v6 parts car that I ran hot I took both parts off and put on my 01 buts its still running the same..
View 7 RepliesHave a 2012 gas powered Escape XLT, 2.5L 4 cylinder.
I need to replace the evap purge valve. Looking at youtube videos and from other posts it seems easy to replace. My problem is where is it located on this Escape?
Is it under the hood or underneath the driver's side? This is just the valve mind you, not the canister in the back.
2004 Ford Escape 2WD 3.0L with about 81,000 miles.
Problem: 2 possibly related
1) If warm up (get to about 190+ degrees) and then cut off engine. Does not start. If I wait about 30 secs and play the gas pedal, then I can get it to start with high revs and after about 15 secs runs normally. Or, I can disconnect the air intake and it'll start fine. But if you stop and try to start again, no joy unless playing with gas pedal.
2) After driving about 20-25 mins, it seems to randomly stall-out while going about 40 mph. When it stalls out, it will restart again after about 30 secs.
Note: Neither of the above throw any codes.
Here's my problem chart after mining the other posts:
Thing to replace/do //// No Code /// Stall while driving /// Won't restart when hot
Fuel Pump //// Yes /// Yes /// Doubt it
Fuel Filter //// Yes /// Yes /// Don't think so
CKP Sensor //// Yes /// Yes /// Yes
CMP Sensor //// Unlikely /// ? /// Possibly
ECT //// Maybe? /// Yes (if too hot) /// Yes
IAC Valve //// Unlikely /// Yes /// No
Thermostat //// Yes /// Yes (if too hot) /// Yes
MAF sensor //// Unlikely /// No /// Yes
What I've done:
- Well, I started looking at the vacuum lines and they were crumbling so I replaced all those (to EGR and all that).
- There is a mystery line that appears to come up from the canister and go to nothing--is this some kind of atmospheric vent?
- My cheap scan tool also shows engine temps getting up to 216 degrees if I make it work (idle high at 2000+ rpm), so I'm suspicious of the cooling system and thinking maybe the ECU is shutting down to avoid overheating.
I'm going to start with flushing the coolant and replacing the ECT and thermostat while doing so. This is relatively inexpensive and ECT can do weird things. The restart problem is consistent, so I'll know if I fixed that right away.
2002 3.0L escape 4WD, stalled twice on me when shifting into reverse after a complete stop. No CEL, truck started right up again....
View 4 RepliesMy wife has a 2004 escape v6 (3.0L). The valve cover seal was leaking so I decided, why not change the plugs since I'm already going to have the intake manifold off.
I got down there, replaced the seal (just the front side, didn't want to disassemble something that wasn't broke) and then replaced all 6 plugs and boots (with springs). Fired it up and everything seemed fine. She went to drive to work and the CEL started to flash. I read the code and there were 4 (Don't remember exactly what they were), but it was a combination of things resulting from a misfire in cylinder 4. Since it was one of the front ones. I just pulled the plugged and replaced it hoping I had gotten a dud from the factory. Nope, still doing it.
I didn't take off the fuel lines, just the air intake on the top. I did not change the coils, but everything was running fine before I changed plugs so logic would dictate it is something I did. Only seems to misfire at higher speeds. Also, her battery light randomly comes on, but the battery and alternator test good. This has been happening a while.
