Ford Ranger / B-Series :: 2003 - Lean Codes / Jerking At Highway Speeds
Dec 10, 2016
I've got a 2003 Ranger 2.3L DOHC, 5 speed, 2WD. It has a check engine light with codes :
P0316-Engine Misfire Detected On Startup
P0704-Clutch Switch Input Circuit Fault
P2195-O2 Sensor Excess Lean Signal Bank 1-Sensor 1
P0171-System Too Lean (Bank 1)
The truck runs fine when coasting or accelerating but when holding a steady light throttle to maintain speed the truck starts bucking and jerking. It's doesn't feel like a misfire, more like a fuel cut out condition. When this happens and you come to a stop, you can smell that the exhaust is very rich coming out of the tailpipe. I've already replaced the upstream O2 sensor and I did a tune up about 15k ago. I'm thinking fuel pump or fuel pressure regulator. I doubt if this is related, but on start up (more so on a cold start up) the A/C compressor clutch kicks in and out 3-5 times and makes a terrible racket.

1998 ranger 4.0L. I ran my scanner on my truck to day and my 2 bank 1 sensors seem to be bouncing between .150 and .700 but my bank 1 sensor 2 seems to be stuck at 680-720 and not bouncing, is this normal?
I did pull a code po135 heater circuit malfunction BANK 1 SENSOR 1 ...
Also I am not sure where my fuel trims should be...
My
ST1 10.0
LT1 25.0
ST2 12.0
LT2 25.0
closed loop.
When I first got the truck I pulled codes for lean bank 1 and 2 also a cylinder #4 misfire and the bank 1 sensor 1 heater circuit. I reset the codes and the heater circuit bank 1 sensor 1 popped the mil light in 5 min. So I am starting with the o2 sensors. I've not found any vacuum leaks at this point.

A while ago I had a '99 Ranger. Long bed, regular cab, 2wd, 5-speed, 2.3. I had really poor acceleration. I was used to Toyota pickups with the 2.4 22RE, and the Ranger was considerably slower to come to highway speeds.
So, I took it to two different dealers, and they told me "that's just the way they are." I guess I believed them and sold the truck. Now, I am kind of thinking about another Ranger. Do people here think the '99 2.3 has an acceleration problem? Are there certain years to avoid the I4 in a Ranger?

165k miles 4x4 6 speed, bone stock unmolested
Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.

2003 Ranger (4.0 L-2wd)...
Codes - random misfire and cylinder banks 1, 2, 3, reads out lean fuel
Will be checking out injectors and rail pressure, however, trouble shooting in general for this issue.

This 2003 ranger 3.0 v6, run very hard at idle, yet it runs and you can drive it around town, ""at"" low rpm, and no hills but it gets from point a to point b
I have no pre ingintion, but a plug that was only 60 days only was burnt out completely on 3rd cyl. bank 1 or as ford call it #3, i am telling you this thing seem like it running on 4 cyl,s kicking back and forth, and replacing everything above made no difference.
On the highway, as long as it is flat or down hill 75-80 mph, as soon as a hill or power to pass is needed it bogs down and slows it self to about 45 mph, I have been though everything i can think of and my next move to to start pulling heads, but i wanted to ask here first.

My 2003 ford ranger 3.0 v6 is having a misfire on start up and it is located in the forth cylinder. Where to start to get rid of this problem. i have already changed all my plugs wires and even the coil pack cleaned out the maf and looked for possible leaks. the car shakes really bad at lights and the check engine light starts to flash. Need diagram of where all the cylinder numbers are at and maybe the firing order?

My '03 Ranger is having a high idle problem. It's a 3.0, manual, 2wd, 141,000 miles. When it's cold it will idle at about 1500 but once I drive it, even just to the end of the block, it will idle at about 3000 and shoot up towards that between shifts. At a traffic light it will idle at 3000 and maybe go down to about 2500. If I bog it down with the clutch it goes right back up once I put the clutch back in or put it in neutral.
I replaced the IAC, no luck. I cleaned the MAF and checked the voltage on the TPS and it is good. I replaced the PVC valve, but the old one was fine anyway. I've sprayed around with carb cleaner and don't notice any difference. I've plugged it into my dad's AutoTap which lets me monitor everything on my laptop and the only thing I can see that looks suspicious is that even with the engine off, the Absolute Throttle Angle reads 18.8%. If I step on the gas with the engine off it goes up to 91.8% so I would imagine that just has to do with the function of the TPS and probably isn't out of the ordinary, but I don't really know what that number means or what the Absolute Throttle Angle is or is supposed to be.
Short of taking the intake plenum off and physically inspecting it for cracks, I'm stumped.

My 94 ranger, 3.0 v6 began to sputter and jerk about a month ago. It does this when ever give more then lite throttle up until about 3000 rpm. I have replaced plugs, wires, coil and cleaned the air flow sensor. I feel like this has worked a little but the problem is still definitely present. When I hit 3k rpm if feels lie the truck begins to run correctly and almost like it had a power ban much like a dirtbike, but again it's just the truck running correct.. And above 3k rpm it runs great... and every so often the problem will completely disappear for 5 minutes or so, then come right back.

I have a 2000 ranger 4x4 4.0l ... It starts jerking in the 3rd gear and up and it gets worse as the gears changes... If it in higher rpm it doesn't do it as much I don't know what could be the problem it's been a recurring problem...

]I recently bought a 1990 ford ranger with a 2.9 @187,000 miles. That being said I went through and changed a few vacuum lines, the oil, air filter, pcv/grommet, and fuel filter.
The problem is it hates to start. I could crank on it for 10 seconds and not a single thing. Sometimes if i turn the key to the off position, wait a second, and try again, Ill get the truck to fire. When it does fire up it just reeks of the lean exhaust. It also gives me some hesitation when I rev it. I did a fuel pressure test (KOEO) last night and it gave me 32 psi and within a minute the needle fell to about 25 psi. I hear the fuel pump run for only 2-3 seconds too.
I've already pulled the MAF off and cleaned it, replaced the TPS, and did a fuel pressure test. The fuel filter is brand new

My 2000 ranger with the 3.0 is only getting around 10 or 11 mpg. It's got a check engine light on but the scanner just says lean condition. The truck also has a rough idle. I've replaced the fuel pressure regulator and fuel filter.

I have a 99 ford ranger xlt 4.0 ohv basically it sputters so bad while driving it sounds like a dump truck but it all started when I changed my o2 sensors but in doing so I broke my heater control valve and when I was going down the road it started sputtering well it started sputtering so I checked the o2 sensors there good and I changed the heater control valve. But nothing so I changed my coil pack spark plugs and wires but still nothing. But on my reader it says cylinders 2,3, and 4 are misfiring and bank 1 and 2 are running lean plus it has a bad aroma of gas in the engine compartment but when it idles its somewhat smooth but when I'm driving it its horrible the sputtering is so bad it takes awhile to get up to speed plus I'm only getting 100 miles to a whole tank that's like 8 or 9 mpg I need to fix this soon. This is my only transportation...

I have a 2000 ranger 4.0l 4x4 automatic transmission 5r55e. When I put it in drive I don't have any problems except in do it starts jerking when I give gas. When I put it in reverse I can move but as soon as I give gas it stalls the engine tranny was sitting in another truck swapped it with mine I changed the filter and 5 1/2 quart of oil.
I when to a transmission shop plugged it inn no codes and he said he would changes all solenoid and valve body gasket but he's not sure what is the problem. So I started to take out valve body and notice the oil is darkish red and was wondering if it was normal or not and if I'm taking that valve body out for nothing or should still go ahead ...

Just put a cold air intake on my 99 f150 with a 4.6. its a CAI with a 4" tube and its not an oiled filter. there is NO vacuum leaks, the mass air flow sensor is clean. I am getting the codes 171 and 174 now and i know its from the intake because that's when it started running lean. Is there any way or anything i can adjust to fix this other than buying a 300 dollar programmer?? If I take it to a ford mechanic will he be able to fix this?

2003 Sport Trac. My car was not starting, told my fuel pump, replaced twice and nothing. Found out about inertia switch and changed it, now car runs.
Before this switch blew out my car was running perfectly, no check engine, nothing. Now i have changed my fuel pump twice and put a brand new fuel filter in and soon after i get lean codes P0171 and P0174. My fuel pressure is 60psi at idle and drops to 0 after about 30 seconds when the car is shut off.
A lot of my intake is new since i did have a vacuum leak before, so i do not suspect that is it, especially since this happened after the new fuel pump. I am completely stuck as to what i should do. And i get hesitation when trying to accelerate sometimes

2003 F150 v6 2wd 170k ... For a year I've only had codes P0171 and P0174 (lean bank 1 and 2). I was told it wouldn't hurt anything... I think now I should have taken care of it.
Anyway 3 weeks ago my truck started running a little rough. It was sputtering and had trouble getting up to speed, sometimes also the air switches from vent to defrost until switch gears and rpms go down. It gradually got a lot worse over 10 days while part was otw. A week ago i changed MAF and cleaned the black thing it's inside of. It started running better but still not good. I pulled my small trailer 2 days ago and it got worse after dropping the trailer.
Today checked codes at AZ and lean codes are gone and have p0304 (#4 misfire) and p0316 (crank sensor problem). Is this related.? Also Right before all the trouble I changed battery and alternator. Also i read online that MAF needed 2 weeks to relearn the way I drive to get correct gas/air ratio? Is that correct?
Also I read so many different things I needed to do during installation... Some say I need to turn key to the on position after unplugging old MAF then plug new one in... turn key to on position 10 times, Rev up engine, drive it rough for the first 2 minutes... etc. Is there a correct way to do it or is it vehicle specific?
Should I start by changing spark plugs and coils? The guy i bought it from and trust said he changed spark plugs right before I bought it. Will it ruin truck if I drive it? I've read so much but everyone says so much different things on the same topic. I'd what to start with or if this is related.

Here are the codes I'm getting:
P0455 - large evap leak
P1451 - main control (evap canister)
P0306 - cylinder 6 misfire
P0174 - bank 2 lean
are these all related? Or two separate issues. I have replaced all the evap lines with new lines. I have a new egr valve, and exhaust manifolds, and what should I look at 1st

I have a 99 f150 with the 4.2l v6 with a 5 speed 173000 miles. I picked it up not to long ago. When I first got it it had both the P0171 & P0174 lean on bank 1&2 it was also siting for a while. I replaced the fuel filter which was filled with black fuel, also changed the PCV valve, cleaned the MAF sensor, and changed the oil. I cleared the code, drove it for a little bit and the light came back on after 20 miles.
I then proceeded to replace the upper and lower intake manifold gaskets. Upon doing that i noticed that i was missing one of the linkages for the IMRC. I went to the junkyard and pulled off another linkage rod off the same motor. ordered new plastic clips, put the IMRC on cleaned everything up and began putting it back together. I also cleaned the Injectors while i had them out as well and put in new spark plugs and wires.
Put everything back together. code was cleared since the battery was disconnected. drove it and then the engine light came back on again. this time it was only the p0174. so i then both the upstream and downstream O2 sensors on bank 2, reset the code and it came back on again. I'm lost.

My o/d has started shifting in and out at speeds over 50mph. It looks like it happens for the tiniest changes in engine loading. A windy day plays havoc and mild inclines. Sometimes the o/d light starts blinking until I switch off then operates normally. Extended warm-up driving seems to work. I've been told the rear axle speed sensor may be going bad but I have no confidence in the advice. I am driving an '02 ranger, 3L flex fuel, 2wd and just went over 100k. The atf is at the correct level but the fluid needs changing in my opinion. There are no engine codes.
