IS F (2008-2014) :: Acceleration Pretty Hard - Bog Down And Hesitate
My 2012 ISF has this weird hesitation going on. On manual mode with Sport, I would try to accelerate pretty hard and around 5k RPM, it would bog down and hesitate. Almost feeling like it's choking.

97 F150 4x4 around 200k miles on it, Drove the truck to town today and it started making a screeching noise when I turn the wheel and moving at slow speed's It is not the typical Ball joint squeak, and they were replaced about 6 months ago. I also get a clicking squeak going down the road, everyone in a while from take of ill get a slide grinding or crunching noise. Also noticed that when taking a curve to the right i feel and hear a slight Bump but I don't when turning to the left/
Also it doesn't have the typical grinding noise of a bad unit bearing, there is a slight roar but Pretty sure that it is just the aggressive tire's... I am about to go out and Jack it up and have a look at it to see what it was. Also if I loosen the Cv nut on at the Hub that would show me if there was any play in the bearing correct? since the cv should keep the bearing's fairly tight even if they are worn?
Ford 7.3L Power Stroke (1999-2003) :: Intermittent Engine Light / Momentary Surge At Highway Speeds
I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?
Ford F-150 - 1997-2003 :: 2000 - Miss / Hesitate And Bog When Shift Into Drive
My father's 2000 F150 5.4L has developed an issue. But the issue only surfaces in it's last gear. As it shifts into overdrive it begins to miss and hesitate and bog. If you disable overdrive you never feel it.
I'm thinking an exhaust restriction. There are no trouble codes, no check engine light. I notice that the note of his exhaust changes as the vehicle warms up, sounds like it's being smothered. And the flow out of the pipe lessens.
My only issue is whether the EGR is causing it or the converters. Haven't seen them go bright red yet, but this has been going on for a good while.
I wanted to get a few opinions before I tear into it today. I'll do a vacuum test on the EGR valve and rescan the codes but don't wanna drive it and heat up the exhaust when i gotta disassemble it.
Ford F-150 - 1997-2003 :: Surge At Any Speed - MAF?
This started about a month ago. The truck surges at any speed as long as the gas pedal is at a static position. There are no codes. I have replaced the fuel filter air cleaner cleaned the maf and did a ton of reading on this issue. Is it the tps? The tps voltage does not fluctuate any when it surges. Maf,? Should be throwing a code right? Same as the egr valve. What am I missing?

I have a 97 F150 with a 4.2. It has started to surge or stall out when I slow down sometimes. It doesn't do this all the time. I replaced the fuel filter about 2 mths ago and replaced the fuel pressure regulator then also. Would the tps have anything to do with it? I haven't had a scan done yet. Thought I would try here first because at one time someone has removed the two cats and the check engine is on all the time.
View 4 RepliesFord F-150 - 1997-2003 :: Shuttering Pretty Alerting Under Light Load At 35 - 45mph - Codes P0302 And P0171
I have a 1998 F150 5.4L 4WD with 192k mi on it. Recently ( suddenly ) the vehicle began shuttering pretty alerting under light load at 35 - 45mph. The engine idle was intermittently smooth then rough. I quickly drove the truck home and ran a Trouble Code check with my Autoxray EZ-scan 4000 and found the two trouble codes P0302 and P0171. I have checked for vacuum hose cracks and found none.
Replaced the fuel filter, PCV valve, and cleaned the MAF sensor ( dirty ).
Right after cleaning the MAF sensor the idle remained smooth - but stumbling immediately when put in drive. Driving at 35-45mph still exhibits intermittent shuttering and occasional very short bursts of what feel like complete engine shut-down. This all is evident under light to moderate load .
At this point what would you recommend ? Replacing the O2 sensor bank #1 ? Or is there a possibility maybe the EGR valve is faulty - or another vacuum valve somewhere ? Intake manifold leak ?
The severe stumbling and very short complete engine shut downs would indicate that maybe the computer is failing or it's a fuel delivery issue? What rational steps to take next ?

View 3 RepliesFord F-150 - 1997-2003 :: Idles Fine With Occasional Surge / Sputters In All Gears Like A Misfire
I have a 01 f-150, 4.6L, with 160k miles on it. Symptoms: It idles fine with an occasional surge. It sputters in all gears like a misfire (all plugs and COPS replaced 2 months ago). Sometimes it stalls out going down highway or as I turn in my driveway. It also seems like its slipping a little without the "hard jerking into gear". Occasionally the rpm meter will peg low and then return to normal.
The only code that I received was P1451. I changed the canister vent solenoid but the symptoms remain. I've checked voltage on the TPS (the variable voltage checked out but I didn't get the 5V ref. voltage). I've cleaned the MAF sensor. I've also changed the fuel filter. I've resistance checked the connector to the PCM and found several pins that are at ground. I'm not sure what to do next.
Ford Excursion :: Truck Shaking Pretty Bad / Also Pulls Hard To The Right
So my 01 has been parked in the garage for about 2 months. Normally on battery tender but it accidentally got unplugged and I didn't realize til yesterday when I went to start it. So I got the battery charged up and put air in my rear drivers tire since every time it sits it goes flat. Well I did all this I so I could take it to get tires today.
Driving to work and its shaking pretty bad at highway speed. Don't recall it doing this yesterday. Never really did this before either. The truck also pulls hard to the right. Its done this for a while so I'm not sure if it's just the tires or needs alignment or something else. Or all of the above.
I'm mainly concerned with why it was shaking. The front tires don't look low however I will check the pressure on my lunch hour today.
Ford F-150 (2004-2008) :: Truck Missing Pretty Bad Going Uphill Or Under Load
I have a 2008 XL 4.2 auto trans with 60,000 miles on it. We purchased a new travel trailer with a total weight just under 5000 lbs that we pulled for about 2000 miles this summer. On the last trip we noticed the truck was missing pretty bad going up hills or under load. After we got home I started to notice the miss at times even not towing. Did a tune up with Motocraft plus and wires and seems to still have a miss at an idle and very low RPM. What would be best to check next?? Would Coil be logical?
View 10 RepliesFord Excursion :: EGR Marbles - Truck Loses Pretty Much All Power Below 2000 RPM / Smokes And Stinks Bad
EGR marbles -- the chunks of carbon that come loose from the EGR cooler / intake manifold and stick the EGR valve open?
I've been getting these on 3 recent occasions, maybe 100 miles or so apart. The truck loses pretty much all power below 2000 rpm, smokes and stinks bad until I pull the EGR valve and dump these out. I'm trying to decide if I need to dig in and do a new EGR cooler and oil cooler. I've read the FordDoctorsDTS article suggesting these are caused by and coming from a leaking EGR cooler (possibly only when very hot) over time.
I'm not currently losing any coolant that I can tell, but was losing some a few months ago (during warmer weather), but also had a leaky heater valve that I replaced at the time. Not sure if the leaky valve would account for the total coolant loss (I lost over a gallon in a few weeks).
Here's the additional details:
- 2004 Excursion with just over 109K miles
- Replaced faulty EGR valve (was sticking open) about 300 miles ago
- Replaced stock turbo with new powermax turbo 300 miles ago. Old was rusty and pitted with sticking unison ring.
- I just did a total coolant flush, oil cooler back-flush, Restore and Restore+ and added new coolant filter
- Replaced thermostat during coolant flush. ECT stays pretty close to 190 degress when warmed up.
- ECT/EOT delta is mostly between 15 to 18 degrees, sometimes slightly lower or higher. Not much change after the coolant flush, but may be slightly improved.
- I've been doing pretty regular wide open throttle tests during recent test drives with the new parts above (I'm thinking this may have broken some of this stuff loose).
Here's today's marbles. They're all dry and will crumble if crushed. They are dull gray on the inside - not metallic as they kind of look here............
Toyota - Camry :: 2001 - Hesitate And Jerk When Try To Accelerate From Slow Speeds
I drive a 2001 Toyota Camry LE, 2.2 4 cylinder. It has about 206k miles on it… About 2 months ago I started to feel slight hesitation when I was driving…. It was so slight I wasn’t sure if it was happening or not. Recently the hesitation has become much worse… typically it will hesitate and jerk when I try to accelerate from slow speeds… this primarily happens when the car is cold. It will also jerk and hesitate when I am cruising at a fixed speed. If I step on the gas, the jerking stops.
Here are known issues and recent work I have had done… in November I replaced my complete exhaust system myself, including the downstream oxygen sensor. The cat is now bad and it will rattle. I had a mechanic replace my water pump, timing belt and all pulleys and tensioners associated with it about 2 weeks ago. The hesitation predated this problem.
About 5 years ago I replaced my own plugs and wires… when I did this; I noticed oil on one plug. This was for the cylinder closest to the driver’s side. I never noticed any issues with the performance of my car related to the oil, and I do not burn through much… perhaps a quart every 2 months. About a week ago I replaced my plugs and noticed the oil again. I do not know if this relates to my hesitation problem or not. I also filled my tank and used a container of injector cleaner, thinking perhaps a clogged injector was causing the problem.
The problem still exists.
Now I am thinking it might be one of two problems… either a defective ignition coil or a bad throttle position sensor. Yesterday I borrowed a code reader… it told me I had “long fuel trim in bank 1”.
Ford 6.0L Power Stroke Diesel :: Truck Is Starting To Surge A Bit Like ICP Sensor Going Bad
I started having an issue with a rough idle soon after startup about a month ago. I thought it might have been stiction so I added some Archoil stuff the other day to my oil interval change and although I have not put too many miles on it, the rough idle is still there.
At startup the engine runs great. I did notice a few times a little longer than normal crank (~3 seconds) where other times it fires up in less than 1 second. This has happened twice in the last month. Once the engine runs for about a minute I get an uneven idle......I wouldnt necessarily call it a miss per say. I took some readings for the ICP and IPR and can provide them if someone needs them. Once the truck warms up it seems to idle better but still not 100%. I have no power loss, no hesitations jut a weird idle with intermittent surging while in gear.
The truck is starting to surge a bit like an ICP sensor going bad but not as pronounced as the last time this happened to me 4 years ago. Basically trying to get opinions as to what it might be or what to check next. I am leaning toward one of three things.....stiction, ICP or IPR valve (original). FICM voltage is good but my fuel pressure gauge broke, but the blue spring upgrade I did.
Ford F-150 - 1997-2003 :: Overheating At Highway Speeds
1999 F150, 6 cyl. 4.2L, 233,000 miles. My temp gauge went way high on the interstate so I assumed I had a bad thermostat. replaced it with a genuine Ford themostat, added coolant and here's where I'm at.
1. Let it idle up to operating temp. When it was warm, the heater was blowing cold air.
2. Thermostat opened up, top radiator hose was hot and full of coolant, still no heat in cab.
3. Took it for a ride on the hwy. Heat started to work in cab, temp gauge went way up. I slowed down and went home down a side road. Temp gauge went back to normal and stayed there. Only driving about 30 mph.
I don't get why I'm overheating at 60mph. My best guess is I have some sort of obstruction in the cooling system.
Ford F-150 - 1997-2003 :: Shake / Vibration At High Speeds
I purchased a 2003 F-150 Screw a few months back. Within a week I noticed a noise that sounded like a bad ujoint. To it to a shop and they confirmed it. They told me they replaced both. I only drive about 4 miles to work around 40 mph. Friday I had to go out of town and this was the trucks 1st road trip. I noticed that around 55 the truck feels fine. At 65 there is a shake / vibration. At 75 it is very noticeable. At 1st I though front end, but after a few hour I noticed the feeling can be felt in the seat of my pants type of thing. Or my foot on the kicker panel. Truck has 27K on it.
View 4 RepliesFord F-150 - 1997-2003 :: 1998 - Shudder / Hesitation At Certain Speeds
Just bought a 1998 5.4l F-150 Lariat. 136,000 miles.
Question about the overdrive button on trans handle. When I push the button, I don't see any light turn on (or off) and I don't feel any change in the gear ratio or increase/decrease in rpm's. I assume since the button in there marked "overdrive" that the vehicle in fact was equipped with it. Could it be a bad button, fuse, or ?
Also, it just started the shudder/hesitation at certain speeds that I see a lot on these threads. Seems like that is a coil issue as the description in many threads is exactly what I am experiencing to incl the rotten egg/fuel odor. However, it started the same day (not same time, later same day) I decided to push the overdrive button while checking out all the things on the truck.
