I just changed my 4.6L. Now my tranny is starting to serge and buck it won't go in rev. But when I put it in D it started to clunk and buck. RPM would go up speed went down.
View 1 RepliesSo my buddy was driving my truck and boat through Amarillo and suddeny had a buck/surge accompanied with black smoke. I left my torque app with him. Its throwing codes: P2287,2285, and P????(fault log got erased and I'm going from memory) concerning #8 cyl. I got there today and we noticed coolant leak on left side. Its small and I cant tell the source, but it is wetting the exhaust manifold on left side. Also now its blowing white, black, grey smoke. At idle its more white/ grey. Under load it mixes a little blck in. I only had time to check the ICP on torque and at idle its bouncing from 0.9 to 1.1. Unplugged ICP ran about the same. Still started and idled fine with white smoke. No oil in ICP or connector.
So I'm no expert but I think ive got a bad icp and something else going on. I didn't pull the egr valve and look so no idea on the cooler ,yup syill have the cooler. Degas has a small amount of white residue directly under the cap but no puking. Degas is just below the max line (on the sticker).
One other note only code originally was the 2287 last night. Now this am there was the other codes ref'd above.
New here. I have a 2001 F150 which i love but lately has been an issue. I started it up a few weeks ago after it set over night. i threw it in to reverse and notice it hesitating while reversing and it has small trouble accelerating but does buck and jerk while trying to maintain speed. So I took it to my well trusted mechanic and he ran compression test and ran the highly prolific OTC scanner on it and nothing. I have changed my mass flow sensor and I dont show any misfires or any codes pending. I did replace a busted catalytic convertor a couple months back. Im running out of places to turn.
View 6 RepliesThis 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?
View 8 RepliesI 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 RepliesI 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).
View 14 RepliesI have a 2002 F150 5.4 2 valve. only when the engine is cold, everyone once in a while the engine will surge up and down about 2-300 RPMs for about 10 seconds. also right when I put it in drive it will surge. I was thinking about pulling off the trottle body and cleaning it.
View 3 RepliesI 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.
is it possible to put a 351 or a 302 in a 97 f150 with the 5.4 e40d trans is so what all would have to be done in order for everything to work rite??
View 9 RepliesOk so when I come to a full stop my truck doesn't want to shift right when I take off where do I need to start looking
View 7 RepliesI have a 1998 f 150 v8 4.6 ltr xlt. A mechanic told me that if my tranny gets hot the OVERDRIVE LIGHT will start to blink. It sounds strange to me, should I have a guage installed? I will be towing a trailer this summer.
View 8 RepliesI have a 1997 F150 4 x 4 with the 5.4 overdrive transmission. When I accelerate from a stop I can feel the slip of the transmission until I reach exactly 35 miles an hour. Above 35 seems to be normal and have plenty of torque.
The funny thing about this is I have had a 2001 Windstar same 35 miles an hour. I have also owned a 1997 Ford Explorer with this exact same issue. Three different motor and trans combination that will not lock up until you reach 35 miles an hour.
The truck has 213,000 I have replaced all coils fuel filters catalytic converter and torque converter. Have exterior tranny cooler. engine runs good and strong. And no code I have a reader.
I have 97 f150 x-cab 4.6 auto 4x4. I'm gettin ready to pull motor & trans to rebuild both. I was wondering if I can pull both while still bolted together without having to remove the cab??? And what else will needed to be removed.
View 6 RepliesI have a 2001 f150 5.4 4x4 with the 4R70W trans. its leaking fluid from somewhere. its not the pan gasket or the seal. it seems to be coming from the top somewhere. the dipstick tube has new o-rings. and the cooler lines have been replaced and are not leaking either. Where else it could be coming from. the passenger side of the bell housing is wet with fluid.
View 11 RepliesI've got a 1997 f150, 4.6. It sat for year and a half, trans went out and it wasn't my primary vehicle so wasn't to worried about fixing it. Until now, well got a new trans put in it, fired it up. And had a misfire, #3 and #8. Changed plugs and wires, same thing. Getting spark at the plug. So I changed both injectors, still nothing! I'm kind of stumped now.
View 4 RepliesI 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.
I have a 2003 screw 4x2 with the 4.6, 148,000 miles, and I'm not sure what kind of transmission. Recently when the truck would shift into second it would hesitate and I would feel a slight grind, but it only did it when it would shift at 2000 rpm, if it shifted at 2500 rpm it would shift fine. I checked the fluid level, it was full, it smelled okay, looked *fine.
After pulling a boat (19 foot bass boat...nothing too heavy) it started to shake violently when I'd take off from a red light. So I dropped the pan and changed the filter, The fluid was dark red and smelled a little burnt. I put 4qts of fluid in it along with some Lucas transmission fix. The shake during take off is gone, and the grinding while shifting into second got a lot better but didn't go away completely.
However, now the grinding into second has has gotten worse again, and if I make a right turn from a red light it grinds and feels like its slipping until it shifts. I am not sure why making a right turn would affect it but its definitely worse when i turn right, left turns are fine. I'm guessing my transmission is going out and I just need to get it rebuilt...
The truck:
2000 4X2 F150
4.2l V6
280k miles/ some towing
The problem : The trans has a hard time getting into 1st gear. When you put it into gear you have to rev it to about 3k (when it's warm, 4k when cold) RPMs at which time you feel a definite engagement and it goes through the rest of the gears just fine. Once it's warm it will do stop and go traffic as long as you start it with the OD off.
The background : Orobably the stock motorcraft filter on there, and I don't think the oil has been changed in the life of the trans, but I do know that it's never been ran low on fluid. I took a gander at it and found a plug where a gear type speedo went on older models to be loose and leaking. tightened it up about two full turns. also noticed what looks to be a leak where the main case meets the output shaft housing. now I know neither of these are the cause of my headache but I do wonder if the second leak might be a sign.
The research : I've been looking for almost a week now for a solution. I've been all over TCCoA, Explorer Forum,10 pages of search here on FTE and various other Ford based websites and have come across a single thread with the same symptoms but the OP never came back with a solution.
The plan : A fluid/filter change (and flush) is definitely in the plans as well as inline filter for my own satisfaction. from what I've read the stock 1-2 accumulator is known to go bad on some of these and if I have the pan off might as well check anyways.
I bought a 1997 f150 with 160l miles on it. It is a 4x4 with the 5.4 v automatic. While I'm drive and in 4th and 5th gear, the tranny shakes the whole truck and then shifts hard! I check the fluid and it's still good and red but looks like there is to much. I'm planning on removing some and adding some lucus additive in it. What could cause this???
View 8 RepliesI have a minor leak at the base of the trans dipstick tube. I assume that the tube is press in ? has an o-ring ? I put some silicone around the area and that worked about a week, the fluid is probably eating through that type sealant. The trans is a 4r70. Seems to me that the actual tube should be ok and having never dealt with replacing one I want a little advice before yanking it out.
View 11 RepliesI recently purchased a f150 with a reg cab short bed 4.6 4x4, and when you put it in drive the it shifts up to second fine, but when goes to third just revs up doesnt pull at all. Have to shut o.d. off and goes steady but run 2500 rpms to go 40 mph. I was told to check the solenoids but i dont know, if i do need a new trans how do i identify my trans. I know it has the code "U" on the door sticker, but its an 4r70 w code-w. But the junk yard has a YL3P-FA and a YL3P-JA?
