Ford F-150 - 1997-2003 :: Surge Or Stall Out When Slow Down Sometimes
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.

I have a 97 F150 4.2l auto 4x4. The truck seems to surge or hesitate at pretty much all speeds. I have had the truck on fords so-called super "sbds" computer and they found nothing. I am taking it tuesday to have the o'2 sensors and CAT. Convertors checked at a local parts/service store. Also found out today that my speedometer is 5 mph to slow (doing 65 but speedo only registers 60).

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 6.0L Power Stroke Diesel :: Surge Or Revving When Getting Up To Cruising Speed
I've been getting a surge or revs when getting up to cruising speed before it drops into overdrive or or a constant speed. Happens around 1800-2200 rpm before up shifting to the next gear. More noticeable if under a load or going up a grade when it will hold gear longer before shifting. Only thing I can think of that would be related is the truck does lack some power on a cold start for the first couple miles before getting up to temp. I've cleaned the ebp sensor and it appears to be working correctly, reading within .1-.2 of BAR/MAP key one engine off. VGT solenoid is clean but have no real way to tell if it's working correctly. Other values icp/ipr temps fluid levels appear to be correct. Just changed the oil and it continues, changed the transmission oil and filter about 3000 miles ago. I've had this going on for about 1000. Started about the same time I changed tunes to PHP. They haven't been able to find anything in the tuning yet that could be causing this or if it is just making it show up now.

My 2000 F150 started knocking, it does this after I get up to speed and let off the gas a bit, it will know as I push on the gas again but if I push heavy on the gas it dose not knock, What could if be? By the way it is a hard knock not a pinging sound.
View 3 RepliesFord F-150 - 1997-2003 :: 2001 - Shudders At Low Speed
2001 S-Crew, 4RW70, 5.4L, 189,000 miles. This started two years ago and first became apparent when I made a hard/panic stop. In fact, the first time it did it I was going to go through a traffic light and hit the brakes at the last second so I didn't actually run the red light. The truck shook like it missed for a second. That was unlikely as the coils and plugs were relatively new.
Here's what it does. When sitting still, in gear and you let off the brake but do not touch the accelerator, the truck will start to move as expected. It immediately shudders as it passes through 3-5 mph and then stops. It shifts through all the gears flawlessly, has no sign of the dreaded torque converter issue. It also does it as you come to a stop- as you come to a full stop and the trans shifts into 1st it shudders just as you come to a halt.
It started doing two years ago and never progressed. It's been the same until just recently when the weather got warm again. It's gotten a bunch worse in the last week and now the truck actually feels like it is idling rough sitting at a stop. (It's not- it's running fine.) But it feels like clutch chatter in a manual. Fluid changes have been routinely done every 30,000-40,000 miles, trans fluid is clear and not burnt, temps are normal.
As I said, it behaves perfectly the rest of the time and even tows my 20' 4,000 lb. boat just fine. Just that initial moment of take-off and at the stop. If I hit the gas when taking off I never feel it. Likewise, if you shift into neutral and coast to a stop it doesn't do it.

View 1 RepliesFord F-150 - 1997-2003 :: IAC Over Speed Error Code P1506
About 3 days ago I noticed my engine RPM was around 250 higher than usual. Usually my truck idles around 550-600 rpm (I know this is low). Anyway, yesterday it threw the P1506 "IAC over Speed Error" Code. It is idling very rough, shifting weird, but does crank up fine.
My truck is now at 93,000 miles and I just cleaned the IAC at 87,000 miles due to the common no start condition. I guess I am going to get a new IAC now since another code came up.
Well, my question is it came up with two other codes also:
P0171 - System too Lean, Bank No. 1
P0174 - System too Lean, Bank No. 2
Do you think the P1506 (IAC Code) made the O2 Sensor codes show up or is it really the O2 Sensors? I just changed my two upstream O2 Sensors around 90,000 miles. Should I get a new IAC or try to clean it again?
C/K :: 1998 - RPMs Will Surge By About 500 - 600 While Driving At Constant Speed
A few days ago my 98 C1500 started having what I can only imagine is some type of torque converter issue. While driving at a constant speed the RPM will surge by about 500-600. This surge does not coincide with any type of acceleration, it's more like the converter is letting go and the RPM's just rise and fall back down. The fluctuations also seem to stop after about 15 minutes of normal driving. I have had no real noticeable transmission issues. At first i assumed it was my tranny fluid just breaking down so to get me home I used a bottle of Lucas.
The bottle seemed to do the trick for only a couple of days and now the problem is back...no better, no worse. The only difference I have noticed is that before the addition of the Lucas my fluid looked perfect and now it seems there is a bit of varnish. No smell, nothing seems burnt, just a little dirty. I haven't changed the tranny fluid for about 70k and the truck now has roughly 160K on it. My concern is that if I do change it the transmission will crap completely and I'll be on the hook for a rebuild.
Ford F-150 - 1997-2003 :: Blower Fan Speed Doesn't Increase On Level 3
I recently got a 2002 f150 5.4. The fan speed works on 1 & 2, and 4. It does blow on level 3, but it seems to blow at the same cfm as level 2. I'm thinking this can't be right. But, if it was a simple resistor issue, it wouldn't run at all on level 3, right? So, where I should look first.

I have a 98 F150 4x4. I had some trans trouble so I pulled it out and had it rebuilt. Now when it shifts into drive the rpms speed up right before it shifts. What is causing the trans to do this? It doesn't do it all the time, only if I take off faster the usual which is most of the time.
View 1 RepliesFord F-150 - 1997-2003 :: 1999 - IAC Over Speed Error Code P1506
1999 F150 4.2L 125K miles.... My problems started about a month ago. I had a P1506 error. The engine was running fine but received the error code. I replaced the IAC and the air filter. Engine still running fine. A week later I received a code for the Intake Air Temp Sensor (don't remember the code). The engine still running great. I bought a new Air Temp Sensor and noticed the wires from the Air Temp Sensor were rubbing against the belt and had been severed. I made a mistake when replacing the air filter of not checking the wires (confession is good right).
The engine also constantly ran a fast idle 2000 to 2500 at this time. I repaired the wires. The engine light went off and idle now starts great and smooth but when heats up will will go to 2000-2500. I then decided to replace the Air Temp Sensor hoping to fix idle problem. Engine still idle fast when warm. However, when I come to a stop and put in neutral the engine will take a minute but go down to normal idle after sitting. Engine light stayed off for a week. Now engine light back on with original code P1506. Idle is still not working correctly.
I feel like I made it worse than it was originally and not sure what to try next.
Ford F-150 - 1997-2003 :: 2001 - Shakes Violently At Consistent Speed?
2001 F150 4x4 harsh shaking. When driving at consistent speeds the truck begins to shutter and shake, begins as a light shake and becomes extremely harsh fast. This is not like a vibration that can be felt, but a really harsh shaking of the entire truck.
The truck continues to shake after taking foot off gas and braking. It will shake harshly even when braking and slowed down to 5mph, but instantly goes away once at a complete stop. Accelerate immediately after coming to a complete stop and it completely goes away and drives normal for a day.
Check Engine light has not come on. Tachometer stays consistent RPM. Shift into neutral does not stop shaking. Only coming to a complete stop ether in drive or neutral does the shaking stop. It happens driving at consistent speeds going 35mph & 65mph, etc. Any thoughts on what the issue could be?
Lexus GX 2010+ :: GX460 - Low Speed Transmission Surge Or Hesitation
Experiencing a low speed transmission surge or hesitation when applying first applying the gas at parking lot speeds.? I especially notice it when traveling downhill or a slight decline. The motor revs as if in neutral then the transmission catches on. I mentioned it to the dealer at the 1000 mile check up and they said they could not find anything wrong. I'm getting ready to take it in for the 5000 mile service.
View 8 RepliesFord F-150 - 1997-2003 :: Engine Just Died While Pulling A Boat At Highway Speed
I have a '97 4.6L 4x4. I've had a few issues recently and am at wits end.
Symptoms: while pulling a boat at highway speed, the engine engine just died. After waiting about 20 minutes for a buddy to show up with a tow rope, it started up and ran fine...until I got home (10 miles). I parked and after approx 5 minutes of idling it died again. No CEL, and found no codes when scanned. 15 minutes pass, it fires up and works fine.
The next day, I hook the boat up again, dive to the lake, go fishing, drive home. Everything was fine. I unhook the boat and drive to work. Half way there my voltage gauge starts falling and 5 miles later all of my gauges end electric stuff dies. I drive two more miles to work and strange beep starts coming from under the dash on the passenger side (I think). After my 12 hour shift it starts and I start my 10 mile commute. Half way through I lose electrical power again but make it home. Now it doesn't have the juice to turn over.
Are these problems related, and what are the possible causes and cures? On an unrelated note, what's the easiest way to replace a rear leaf spring shackle?
