Default Re: 2003 Ranger 3.0L Engine misses and hesitates at 4000 rpms when accelerating.

Honestly, I'm really not sure at the moment. I've been ignoring the misfire and hesitation for awhile now but for the past 2 weeks I started to notice when I start my truck up in the mornings and when the engine is cold, I can feel it missing. I've never had that before. I want to determine if its related to the Camshaft Synchronizer in anyway.

Well I changed my cam shaft sync and sensor, got them for 80 bucks I know a guy at maslack, but due to there being ice all the time I have to wait till spring to see if that resolved my issue or not. I suggest doing it you self. If it is your issue. YouTube ford ranger camshaft synchro replacement and watch Bob Planks videos on it. Honestly the best I found. If you have troubles lining the "tooth" up with the old one he has an additional video on it just have to look thru his videos. But when you try to line it up and it fits into place but is like an sixteenth of an inch off that's okay so longs as it's dam near close. Also It's in the way back of engine block so sitting on the front don't damage anything

Ok, sorry for the late update. My Camshaft Synchronizer(Motorcraft) was replaced and now the bucking effect or loss of power at high speed and rpm went away. Although I still have random misfires only upon starting the engine and taking off. It goes away very quick though. This occurs when the engine is cold or warm. I was advised by a mechanic that it could be my ignition coil. I plan on replacing it very soon.

And then there was that stupid bird chirping under my hood. I said "Oh great!" Now a belt problem too? Well the more I listened the more I noticed it coming from the rear of the engine. Now I bought this 2001 Ranger a couple of years ago and it ran great until now. Duh! Well now it does have 125,514 miles on it. Well I started researching the web with my friend Google, and low and behold this RangerForum group comes up. So I join!
Well don't you know I came across some thread about the chirping camshaft syncronizer. And later found a video with the same noise. So after reading up on all I could about it I ventured out and bought a (Motorcraft) sync and sensor from Ford.
I followed a video on Youtube to change it out. Now with no mechanical experience I marked its position, pulled the other one out and dropped in a magnetic pickup tool to see if there was metal particles in the drain pan. Wala! Yes... a lot. Not good huh!
Ok, not much play in the old one but sure squeaked hand turning it. Now the fun part was trying to put the new one back in the hole and match the markings. Well it wouldn't go in. Found to have a burr in the casting of the two halves when manufactured. Just filed it down, cleaned it and re-oiled it. This time it dropped down. Not where it should but after several attempts it went in and matched the marks transferred from old one. No I didn't use a positioning tool. So after putting all back together I hooked up the battery and started the engine. Let it warm up until gauge showed normal temps. Now comes the revving of the motor. Pushed pedal down slowly to 3000 rpm's. Good, now higher to 4000. Good. Purrrrrrrssssssss like a kitten. Now the road trip! Wow! Power again! Deliberately drove in lower gears to take up high rev's. And it is running perfect again.

Guy's! Guru's and Wana-be's,,, Thank You all!

I had the same issues with my 2003 Ford Ranger Edge, 2 dr, Standard cab, 3.0L, 5 speed manual (167500 miles). I would be driving down the road. Shift 2nd to 3rd at 3000 to 3500 RPMs the truck would hesitate/misfire/jerk and finally started making a loud winey/howling noise. Self test PCM-passed, Scope Check passed, MODE 6 indicated #1, 2, 3 Cylinders misfire NPF Road test. I replaced the fuel filter, air filter and TPS. Checked the plugs/wires, PCM Relay, Coil Pack, Cleaned CMP Sensor, Cleaned PCM Connector, Cleaned MAP Connector; nothing helped. I came across this blog and decided to give this a try. I had the senor and Camshaft synchronizer replaced. Took the truck for a test ride. Runs like new... Thanks for the post
