Ford F-150 - 1997-2003 :: 2002 - Running Rough - PO316 And PO306 Codes
Feb 20, 2007
These are the code that keep spitting out. I have a 2002 f150 5.4L supercrewand it is running rough. I had this problem about 3 months back but i didnot get any codes from the computer i washed my truck a 1/2 day earlier, 2days later it went away. this time it has spit out 4 codes a po306/po307/po300/po316. the po307 and the po300 are gone, but the other two remain and it is still running rough 2days later. i had just washed my truck 30min. before, it started happening, is there water somewhere? My dad (long time mechanic) says use wire dry on the cops and it will go away. I have read other post on misfiring and I am still not sure what to do?

My truck started to idle very rough. I pulled the codes and I got po308 and po316. First I changed plug #8, the electrode was nearly gone. I have never seen a plug in worse shape. Replaced that plug and fired it up, it still idled rough and threw the same codes. Next I moved the #8 coil pack to the #1 location and vice-versa, still the rough idle and same codes. Then I moved the #8 injector to the #1 location same results. Finally I tested compression in the #8 cylinder and it read 32psi ( not good) everything else read 150 to 160 psi. Squirted some oil into #8 and no difference in compression.The truck is a 2002 with 184,000 miles, it burns a quart of oil every couple weeks but still is in perfect shape. Should I bite the bullet and invest in a remanufactured engine for 2500.00? I put one in my 97 f 150 a few years ago with no problems.

2002 F150 5.4 v8,,, I had troubles just over a month ago with a po305 code. i got the truck fixed with 2 new coils n some gaskets. I am having these po353 & po171 codes pop up now. The truck is running rough and I am curious to if its just another coil problem or if their is something I am overlooking or just don't know about?

2001 F150 4.6. Just replaced all 4 oxygen sensors and spark plugs. Replaced rubber grommet on brake booster as it was leaking vacuum.
Truck is still running rough hesitating.
Pulled codes came up as PO141 oxygen sensor heater circuit. PO171 passenger side cylinders running lean. Fuel trim outside limits.

Just got a 98 f150 w/ 5.4 4x4 excab. It idles fine but under light accleration. It starts bucking and missing bad, if I step on it, it down shifts and accelerates fine. If I try to maintain one speed it misses bad. It is not throwing any codes right now. The check engine light did come on for like a minute but went back off before I could have it read. I hooked up a scanner just to see if any codes were stored and got p0300 and p0301. I am going to clean the MAF and check for vacuum leaks. I hear the rear plug and coils can get water in them causing similar problems.

This truck has been running fine then as my son was getting off the interstate it started acting like it was running out of gas then died. I went to tow him in and it cranked right up and never had another problem for a week. Yesterday he drove 80 miles away when the same thing happened shortly after he got off the interstate. He replaced the fuel filter which it probably needed but still won't start and stay running. It cranks right up the immediately dies.
First time this happened it was throwing codes PO171 and PO174. Now it is not showing any DTC's at all and none pending. We see no frayed or bad wires and all vacuum hoses seem fine. He cleaned the MAF with no change in behavior.... If it were an outboard motor or some kind of boat I'd say the problem is in the ignition switch except it does run a very short time before dying. If I immediately try to restart it won't stay running. If I let it sit for a while then it will run for about a half minute.

My girlfriend has a 2002 F-150 with the 4.6 V8 and I was going to change the spark plugs for her. She said it started running rough and it threw a code and check engine light. She took it for a scan and they told her the number 5 plug was mis-firing. I'm fairly handy and bought a set of the recommended Motorcraft plugs from Rock Auto, AGSF32PM. It also matched the number in the owners manual so I thought I was pretty safe.
Funny thing, when I took the old ones out, they were AGSF22WM's instead. My thinking is they are a colder plug than the supposedly original equipment, but I don't think they've been changed before. They looked well used but the color was good. The truck has about 135K on it.
Long story short, and to get to the question(s), Would there be any reason the factory would have put a different plug in the engine than what is listed? Am I asking for trouble going with a hotter plug than what's been in there (pinging or timing retardation/loss of power)? Am I just overthinking the whole thing and need to put it back together and drive it?

E99 Romps on start up and randomly dying. Bought this truck about 3 weeks ago. Previous owner mentioned he had issues with it getting hot and shutting off and not starting. Has new IPR, ICP and pigtail, I just put in a new fuel filter. Has 206k miles on it and is the 4R100.
The past two days after sitting all night I have been cycling the key twice and it hasn't done its romp. Typically when it does I can tap the pedal once and it goes away. This I could deal with but its started to die randomly while driving, never while cruising down the road. Its either just after starting it and rolling slowly or slowing down for a stop or to turn. When it dies, I can put it in neutral and it fires back up no problem. SES light usually comes on for about 10-15 seconds after but goes away.
Replaced the grey CPS that was in it with a dark grey one from RiffRaff Diesel. Got a Edge CTS2 to figure out the problem, the codes Im getting are P1280 and P1247.
The ICP pigtail they replaced they spliced on with butt connectors. I plan on pulling it to check for oil and make sure it does look new and redo the connections with solder then shrink wrap them.
I was told to check the IPR% under full throttle which I did and it never went higher than 36.7
The truck did start running rough around 45-50 mph and I did get a video of the ICP jumping around while cruising down the road.
Then I went through a drive through and the truck kind of hiccuped like it wanted to stall and the ICP went right to 725 PSI and idled up and stayed there until I started to leave.
Truck is pretty much stock, K&N air intake and muffler cut out and straight piped.
Here is a link to the videos I got :
e99 7.3 ICP fluctuation while driving - YouTube
e99 ICP steady at 725 PSI after acting like it wanted to stall. - YouTube

My 1997 f150 4.2L 2 wheel drive truck has been running rough only in the morning. In the last year I have changed the plugs, wires etc. As soon as I start the truck and attempt to drive, it is very hesitant, runs rough etc., but if I only give it a little gas and not push it - the truck will run fine. This will only last about 45 seconds and then it runs normal for the rest of the day. I do not have original FORD sparkplugs and someone told me that might be why. I spoke to a mechanic (did not work for Ford) and he told me it wouldn't make a difference.

so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:
P0453 (evap emission ctrl sys pressure sensor high input),
P0141,
P0153,
P0135(oxy sensors),
P0401exhaust gas recirculation flow insuff detected,
P0460fuel tank level indicator circuit error.
And I believe I've told everything i know ...

I am having a problem with my 1997 f150 4.2 v6. The engine is running rough at idle and while driving. It's running so rough that it vibrates the entire cab of the truck. I found water in the oil when I was trying to fix the problem. I have since had the heads redone and replaced all of the gaskets thinking this was the reason for the rough idling and rough driving. It wasn't; doing this fixed the water in the oil but still I have the rough running engine at idle and driving.
I have replaced the EGR valve, plugs and wires, pcv valve, replaced the coil pack, fuel filter and air filter (everything has been replaced with ford recommended parts because I have read that the engine I have doesn't like after market parts). While driving the engine vibrates and sound as if it's going in a cycle in a rhythmic sort of way (like a washing machine goes in a cycle), best way I can explain it. I have come to the end of what I think it is?

I have a 1998 F150 4.6 2wd regular cab with 255,000 miles on it. Lately it has had some problems. The first is that it will run really rough when under a load, meaning when I step on the gas. It runs smooth at idle and at cruise but when I step on the accelerator it bogs way down and almost shuts off. I have changed the spark plugs, spark plug wires, coil packs and fuel filter. Now I'm thinking maybe fuel pump?
The other issue is that when the truck is having to work a little harder (i.e. pulling a trailer or running in the summer with the AC on) it will start to run hot. I have changed the thermostat, flushed the coolant, cleaned out the radiator, etc. and it still does it. Could both of my issues be related to a fuel problem??

I purchased a 1999 F-150 Lariat 4x4 automatic transmission about a year ago. When I did, the previous owner told me about an idle issue that he has occasionally. He said that the issue was with the IAC. He claimed that he had replaced it several times but "it was hard to get a good aftermarket IAC that actually works". He said he tried several, but it never fixed the issue. That sounds like he wasn't replacing the defective part to me, but I don't know. This is my first truck to ever purchase.
Fast forward a bit (about a year), and I have had intermittent issues with idle and running rough since I bought the truck. I don't drive the truck that often, but they are becoming more common, so I want to get things fixed now.
Issues:
1. When running at idle, especially in park, the idle seems to fluctuate and never stay consistent. The idle drops as soon as I put it into drive, and the truck jerks a bit when going into drive because the idle was too high in park. It has never died while at idle, however.
2. When driving, especially up a slight or moderate hill, the power seems low and the truck starts to ping and jerk. The only way I can avoid the jerking is to stomp on the accelerator and go into a lower gear. And even when doing that, I still can notice an ever so slight jerk.
3. This past week, it was rough for an entire 40 mile journey on the interstate. Slight ping the entire ride home. When I pulled into the driveway, it was jerking until I turned it off. I haven't tried to drive it sense.
Potential issues:
1. IAC - maybe the previous owner was right. Maybe I should replace it again, or clean it with some carb cleaner.
2. Cam Phasers - I saw some posts about this on the forum.
3. EGR valve - Also saw some posts about this.
4. Maybe even the transmission? It doesn't seem to have an issue going into or out of gear, though.

I have a 2001 F150 4.6L auto. This truck suddenly started running rough. Cleared all codes and re-scanned after starting truck. The codes are as follows; P0135, P0155, P0443, P0740, P0743, P0758, P1451, P1460, P1747, and P1760.
My question is; is it normal to have this many DTCs come up at once? Could my PCM be faulty causing this problem? Can you swap a pcm from the same year truck with the same options without reprogramming?

2002 F150 - 5.4 ... So just bought this truck about a month an a half ago. No problems but the other day the SES came on. It is showing P0171 and P0174. And P0000 (almost forgot that one) was told that's generic though. Haven't really noticed a difference in the way it's running. Has been extremely cold here in WV but the only thing I can notice (or think I notice) is the gas mileage has gone down a little. After reading some on this forum I'm looking for a vacuum leak correct?

Ok on the way the my 1997 f150 4.6 L 180,000 check engine light started flashing and running rough and then the light went off, Also we took the Aftermarket Dynomax muffler off of it earlier today if that makes any difference, it still has the Cat Converter, New Plugs and Napa Wires.....

My daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?

I have been having some issues with my 97 ford f150 4.6 liter, started out running rough, then hydrolocked with no serious damage, blown intake manifold gasket, fixed that, alternator over charging do to bad voltage regulator, fixed that. and airbag code 52, still working on that, as well as failure to connect when trying to do diagnostic scan. now I am wondering if the engine diagnostic is still even working. still running good just a very slight vibration when warms up. I am not getting any code. or my check engine light is not showing any codes. What I want to do is force a code. What would be the safest way to force a code or force engine light to give a code?
