Ford Ranger / B-Series :: 1998 - Random Misfire / Power Loss / Hesitation - Code P1131

Ok I've been plagued with this very random misfire/power loss/hesitation problem going on a couple of months. You could drive the truck anywhere from 50-300 miles without having an encounter of this problem. It seems to do it now mostly on contiguous long trips over like 30 miles. It one time threw up a P1131 code which quickly went away on it's own. This is a list of stuff that has been recently changed: plugs, wires, coil packs, air filter, pcv valve, fuel injectors, tps, idle air valve, MAF cleaned, fuel filter, and egr valve.

I sprayed with brake cleaner for vacuum leaks around the intake tonight after driving a continuous 50 mile round trip it messed a few times on the way back. When I sprayed the EGR valve mounting area it idled rough when it was hit with brake clean and idled up. So there's a leak there. Or is it stuck? It will be driving normal and usually when you come to a stop the engine will start missing really bad and then when you take off there's no power at all. You keep your foot on the gas and eventually it will feel like all the power is just turned on.

If it does it while you're driving highway speeds it will feel like you've lost a cylinder but it's not as dramatic as when you come to a stop and it starts missing. I can't be 100% but I don't think the EGR wasn't leaking before I replaced it and it was still doing the same thing. I'm wondering why the Check Engine Light won't pick up an obvious misfire when you can you actually feel it. And why if it was the vacuum leak would it only start doing it after many miles of driving?

Ford F-150 - 1997-2003 :: Multiple Exhaust Manifold Studs Broken On Both Side / Codes P1131 And P1151

I have a 2000 with a 5.4 and 166K miles. It had multiple exhaust manifold studs broken on both sides. Now that thay is fixed, I am getting the p1131 and p1151 codes. The EGR tube was also replaced at the time of the manifold fix. I checked over all the tubes and electrical connectors to rule out something simple but did not find anything out of place. The intake manifold was replaced with a new Napa one less than 5K miles ago as well.

Could the leaky exhaust manifolds over time set the fuel trim level high and now that they are fixed, the ECM is thinking it is running too rich? Can the ECM be reset to zero? There is also a ticking/rattling noise when you accelerate that seems to be coming from the fuel injectors. I listened with the stethescope and they are the only things that sound like the noise I hear. Could these all be related?

Ford F-150 - 1997-2003 :: 2000 - Code P1151 Lean On Driver Side - Truck Bog Down At About 50 - 60 Mph

I have a 2000 f150 with a 5.4 past few months it has been throwing a p1151 code meaning it is coming up lean on the driver side. I just changed the plugs and it didn't work, neither did changing the fuel and air filters. cant find any vacuum or exhaust leaks. Replaced a bad injector along with the spark plugs and its still coming up lean.

The truck also seems to bog down at about 50-60 mph if i let off the gas and coast it will drop about 300 rpms. It has me confused and annoyed, i have true duals with glass packs could that be causing it?

Ford Ranger / B-Series :: 1998 - Engine Stall Just For A Second Making Truck Buck As It Accelerates

I have a 98 Ranger 4x4 XLT 4.0 5sp. It has 182K miles.

Once in a while it will blow the fuel pump fuse. It'll go 2 years sometimes. And sometimes the engine will stall just for a second making the truck "buck" as it accelerates.

Could it be the pump is about to fail? How long do they normally last? Btw, I change my fuel filter every 2 years, no issue there.

I've owned the truck since new and maintenance is always taken care of. Also, What's the best way to change the pump?

Ford Ranger / B-Series :: 1998 - CEL On / Pending Code P0446

Today my Check Engine Light came on for the first time in years on my 1998 Ford Ranger. It has 363,000 miles on it. But the engine was changed about 150,000 miles ago. It's a 2.5 automatic. It runs good and has no problems until today. I was leaving a shop and when I started up the truck the Check Engine Light came on. It wasn't idling bad but when I went to take off it wouldn't hardly move. I wasn't even able to keep driving. So I stopped and turned it off and restarted it. Then the Check Engine Light was gone and it ran fine. I scanned it when I got home and it a Pending code of P0446.

I've never gotten this one before. It said something was wrong with the fuel vapor vent solenoid open or shorted. I've never replaced anything on the evaporative emission system except a hose under the hood 3 or 4 years ago. I've had to change the fuel pump a couple times. I've never had any wiring issues. I've never hacked into the wiring. I've owned it since it was new. Is it likely that solenoid is failing or the vapor canister is shot? I don't need this to happen again because even if it's in what was called limp mode. there's no way I could've driven it home like that. I couldn't even pull over. I was lucky I was still in a parking lot.

Ford Ranger / B-Series :: 1998 - Clunk Noise Only Happens In First Gear On Takeoff

I've been having this problem for about 2 weeks now, and I am trying to figure it out. I know the video is only 5 seconds but at least you can hear the sound, it only happens in first gear, on take off, about 2-5 seconds after the take off, and the sound is coming from the rear axle area. I cant figure out if its diff or brake related.

Ford Ranger / B-Series :: 1998 - Whining Sound In First Gear And Reverse That Varies According To Engine RPMs

I am looking over a 1998 Ford Ranger. Very low miles for its age (67,000) and kept in very good shape. When I took it for a drive, I noted an issue.

- there's a whining sound in first gear and reverse that varies according to the engine RPMs. I thought it might be the power steering pump, as that whined when I turned the wheel.

However, the noise went away when I shifted to the higher gears. Been a while since I drove a stick - my Bug back in 2003, IIRC.

What I might be getting into? I really like this machine, aside from that issue, and I would like to nail the problem down ASAP...

Ford Ranger / B-Series :: Code P0500 / Speedo Works / ECM Gets No Speed Signal

97 ranger 2.3l 5spd ... I keep getting p0500 code. the speedometer and odometer work fine. I understand they get they're reading from the OSS on the transmission. Now I also have the vss in the axle housing which I believe is what gives the ultimate speed reading to the pcm that way there is no need to ever adjust for axle ratio.

When using the torque app with my obd reader my OBD MPH guage does nothing until I get to about 55 then it bounces around randomly between 20 and 55 and once I hit 60 mph it reads correctly. I have tried 3 different vss sensors checked wire continuity from sensor to firewall examined the teeth/sprocket that gives the vss it's reading and it all checks out...

My questions are:
- What volts or ohms are supposed to come out of the plug end so I can test if the signal to the sensor is working
- Looking for wiring schematics for this sensor to pcm...my schematic only has the oss.
