Ford Excursion :: 2000 - Hesitation / Surge And Stumble Over 1500 RPM
I recently picked up a 2000 Excursion with the 5.4 V8. Engine has 150,000. I got it cheap because it has a surging problem over 1500 RPM. This problem is intermittent.
I have 1 DTC. P1000 which is OBDII checks not complete. I cannot clear this even using the factory procedures. FYI..I have a snap on solus scanner. I think this is a voltage problem, If you try to start the engine with the scanner plugged in, the scanner shuts off, so I'm thinking the PCM loses battery power supply when the starter engages, resetting the PCM.
This problem is NOT a miss.... something isn't opening or shutting off above 1500 RPM. This truck doesn't have an EGR system, it has the EVAP system. This may be the problem, thats why I'm here. OK. heres a list of what I've replaced since I started working on it.
Engine oil and filter
air filter
fuel filter
8 COP's
8 plugs gapped properly
cam position sensor
IAC sensor
MAF sensor
Removed throttle body and cleaned.
Vacuum checks. 22" at purge valve,fuel dia, and vacuum canister
Checking with the scanner at 1500 RPM with problem
SFtrim1% bounces between5-15
SFtrim2% bounces between2-0
LFtrim1% bounces between11-13
LFtrim2% bounces between 5-6
O2S11(mv) bounces between 200-781
O2S21(mv) bounces between 200-800
Ssystem is in closed loop holding throttle at 1500 RPM... Note engine surges when at the RPM or above. I'm thinking the engine is lean, not sure how to read the trim numbers...
Idle is fine ... Problem is intermittent ... Also noticed that engine will only advance spark to 30 degrees @2000 RPM during this problem. I have seen it advance to 38-40 degrees when I do not have this problem, so I kind of understand the power loss,knock etc due to the timing, my question is whats causing it to do this?
EVAP question.... The purge valve should open according to PCM command a certain value, correct? I can monitor the duty cycle % but cannot activate and check proper duty cycle through scanner . When I try to I get an error message of module error -unspecified.
Disconnected hoses at purge valve,Full manifold vacumn on one, nothing on other, no flow through purge valve, but scanner shows 30% duty cycle. I would think the should be a little flow at 30% Maybe my problem? Troubleshoot procedure for the EVAP would be good.
Ford Excursion :: 2000 Will Not Roll Backwards - Some Hesitation To Engage Each Gear?
I have a 2000 Excursion 7.3 4x4 with 237k miles on the original 4R100. Yesterday afternoon I went to back out of a parking space and the truck wouldn't move. When I put it in R, the transmission will engage and upon pressing the gas pedal it acts like it wants to move but will not budge. It rolls forward with no issue or noise. It will not roll backwards at all - not in neutral and not in reverse. The transmission shifts fine but with some hesitation to engage each gear. I have noticed some slippage but nothing crazy.
I 1st thought something might be wrong with the rear end but after some research I think it might be the transmission.
Ford Excursion :: 2000 XLT - Runs Rich Or Lean - Hesitation When Warm
I noticed difference in smoothness of gas pedal recently, I have an sct x4 tuner and it shows the short term fuel is 1.25% on idle. Does it mean rich or lean?! And what is the solution for this symptoms!
2000 5.4l xlt
Note : cold start runs fine, goes hesitant when warm, furthermore I have changed the temp. Sensor....without any difference.
Accent LC (2000-05) :: Will Not Start After Engine Warms Up
Timing belt broke, replaced belt and head camshaft position sensor. After engine is ran awhile 5-10 miles it will not start until it cools down for at least 45 minutes. Even with jumper cables attached.

My hyundai accent 2005, have problem of jerks /die speed after engine get warm, also increase if AC on, when I starts car in morning it works great and no problem but after 3 or 5 km as engine get hotter speed kills,but it happens more or worst in evening at 4 when returning from office and temp is 45+ in riyadh, saudiarabia.
I change air filter, fuel filter, spark plugs, spark cables, also use fuel injector cleaner but still problem remains, I want to tell you its start when I changed engine valve cover gasket due to oil leak, as I changed this problem suddenly appeared, I went to other mechanic but he told me the problem not in valve cover gasket,it is somewhere else he clean my throttle body ,and its works for 2 day only that i felt the problem solved but after two days problem appeared again,there is no engine light power on for any electronic malfunctioning.
Escort :: Engine Starts To Lope And Often Die When Warmed Up
My 1999 escort 2.0L sohc is having idle issues. It idles perfectly after a cold start. When the engine warms up, the engine starts to lope, and often dies. I've searched for leaks and replaced parts that are the most obvious possible reasons. Also replaced some parts that were questionable. The head was cracked and the gasket blown. It was obviously like that for quite some time. There was only a leak between the coolant and cylinder.
So far I've replaced: fuel pump, fuel filter, timing belt, timing belt tensioner, water pump(trashed), thermostat, cts, radiator fan switch, head w/gasket, radiator cap, iac valve, ccrm, pcm/ecu, tps, cleaned maf sensor, cleaned intake, cleaned injectors, new injector o-rings, spark plugs, coil, checked and cleaned pcv valve. Knock sensor is ordered, and O2 sensor will be installed soon.
The loping goes away with the headlight and/or A/C on. The car previously would overheat without the cooling fan switching on, hence the cooling parts being replaced.
Golf VI R :: Lope In Idle When Engine Is Warm
Here's what's done to the car so far:
Evoms CAI
Autotech HPFP Insert
UM Fully Loaded Stage 2
Magnaflow Catback
R8 Coilpacks
Now my problem lies in the fact that the car has an unusual "loping" idle once it's warmed up. I noticed it very slightly when I first installed the catback simply because that exhaust is louder than stock. Now with the tune it seems to be even more noticible and ocasionally the engine will stumble upon a warm startup. I've pulled up VCDS and looked at the timing measuring blocks during idle and it varies between 0 and 13.5 BTDC/ATDC, the lowest the revs go is about 700 and the the car idles most of the time at about 800. A few hundred miles ago there was a code for Fuel pressure too high (P0088) and an o2 sensor reading too rich (P2271), I saved said codes and cleared them and they have not returned.
Ford - Explorer :: 2000 XLS - Engine Hesitation - Constant Hiccup
I purchased my first Ford back in 2006 it was a 1999 Explorer Sport. Gave me a long line of problems from suspension to head gasket repair to rear main seal repair to ANOTHER head gasket repair. But sure enough, like I'm sure many of you have, I fell in love with her. She could do no wrong. Even now that I got her off the road she is still my baby. Now my recently purchased 2000 Explorer XLS which I've only had for about 5 months just yesterday started doing a strange hesitation. Perhaps a misfire. My initial instinct was dirty fuel injectors that hopefully if I'm lucky will be the easiest fix in Ford history. Another hypothesis is a bad plug. Either way, in my mind, that's best case scenario. I have yet to take it in and plan on buying some injector cleaner later on today. When I'm idling there's no problem. It's as soon I step on the gas that I feel the hesitation. Almost like a constant hiccup.
View 6 RepliesCamry :: 1995 V6 - Rough Idle / Engine Lope When Started Cold
We have owned a 95 Camry V6 for 20 years and it has always been reliable. However, several days ago, the car started to have its first engine performance issue. When we start the engine cold, there was rough idle/engine lope. If it was warmed up for about 5-10 minutes, the car was fine for the entire day. but during this rough idle, the car jerked slightly as well if i press on the gas.
Since the symptom began, I took it to local shop A and they replaced all the spark plugs, pcv valve and air filter which did not solve the rough idle/looping problem. The rough idle continued, and few days later, I was unable to start the engine though it cranks. (at least that's what I think it does). Had it towed to shop B and they've replaced oil pump, which they thought to be the problem. I took it home, and the next morning I found myself unable to start the car.
Ford Excursion :: Overheating When Warms Up / Gauge Start To Go Up
Last fall I flushed and changed out my water pump, Thermostat, Coolant Temperature sensor, and coolant reservoir. My 2001 Excursion ran find all fall and winter long. This year I changed out the Fan clutch.
Problem: when it warms up and drive well for a while than the gauge start to go up and start staying its overheating. The weird thing is when I turn on the A/C it brings the temperature back down. When its in gear and running without the A/C it creeps up to almost the red. I cleaned the Radiator and made sure it was clean but it still does the same thing. On top of that, the upper hose (when the car is turned off) seem to colapse slightly.
Other than getting it professional Flushed I don't know. The coolant has nothing to do with the Radiator? I'm pretty much stump with it.
Ford Excursion :: 2000 V10 Won't Start / Engine Does Not Turn Over
My trusty 2000 v10 has begun to give us starting troubles. The symptoms are:
1) Most times it does start normally and runs great.
2) When it won't start - Engine does not turn over
3) Interior lights and other electrics work, battery reads 13v
4) There is a click from the relay when the key is turned
5) Wires look good, no corrosion found in fuse/relay boxes
6) No indication of funny stuff via dash board lights
7) I do not have a code reader
My resolution the past two times has been to verify volts and connections, then wiggle all fuses and relays, wiggle the shifter in the car, then it started.
I have checked the basics and have become suspicious of sensors after running the Pinpoint Test A listed in another post by ~Christina. My forum research indicated that other people had problems with:
- transmission range sensor
- crankshaft sensor.
- cam sensor
So how does one go about finding the location of and testing these? Are there other sensors to investigate?
Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Idles Fine But Runs Rough After Warms Up A Little
2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.
I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.
I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.
Saturn - Sl :: 2000 Will Not Go In Reverse After Car Warms Up
I have a Saturn SL2, 2000, 110k miles, automatic. When the engine is cold, reverse works. After the engine warms up, reverse stops working. It doesn't start moving from being in that gear, nor does it work when I push on the gas. Shifting from First to Second is a little rough at times.
View 2 RepliesFord Excursion :: 2000 V10 - Knock At The Rear Of The Engine / Exhaust Leak?
This is a 2000 EX with 146k miles on it bone stock. I have not done any of the regular maintenance on it yet or even gotten to really check this problem out. I am not driving it at this time mainly due to this problem.
The noise is heard the best at the rear of the engine and underneath the truck as the video shows. It seems to slightly change in sound (maybe a tad bit quieter) once I put it in gear (drive and reverse), I have not really heard a change in it after the truck has warmed up either. It does not sound at all really metallic to me..

Ford Excursion :: 2000 V10 - Check Engine Light Came On - Code P0500
I've got a 2000 ex limited with the v10.4x4. The engine light came on. So I had it scanned. Also the a.b.s light is on.and the overdrive off light was flashing but now isn't. The parts store that scanned it said code was po500. Told me it's a speed sensor but that there's 3 of them on the truck. Which sensor it is.

I also tried jump starting - get same same result. Engine cranks, turns, and then sounds like it is just about to start up normally but it just dies completely. It seems to want to start but just can accelerate the engine high enough to keep it running. Almost like it's flooded on a carb motor.. 2000 V10..
