Hello and thanks to the admins for hosting this site. This is my first posting!
My Ranger is a 2004 with the 3.0 of course and it is a Edge 4X4 with the 5 speed.
I bought this truck last year and it had 75K on the clock. Now ir has about 95K.
The truck has run pretty good up till about 2 weeks ago. I say pretty good because it has always had a little uneven idle warm or cold.
Anyways about two weeks ago during a long weekend trip it started bucking hard and missing through acceleration and at lower rpms. Then the CEL came on.
I nursed it home and if I was easy on the gas and was smooth with my shifts I could get it to be somewhat controllable. When I got to higher rpm's it was much smoother with only a occasional hiccup. At the lower speeds and rpm it was noticeably weak on power.
So I scoured the internet and through the other website and this one as well as a bunch of other sources I found out about the cam synchro issues. Though my truck seemed to be at odds with the symptoms described by all the other complaints I read about. (they all seem to be complaining about bucking & missing @ 3-4K rpm's vs. mine @ lower rpm's) I became very nervous about the possibility of the oil pump not getting driven by the synchro and the obvious disaster that would wreak.
I took the truck to O's and had them scan for codes and it showed to be missing on #1 cylinder but they could not tell me anything other than that. so I decided to change out the synchro and cam position sensor along with the plugs and wires. I installed the synchro using the marking method by marking the tang to synchro body position & synchro body to intake manifold position. I then transferred those marks to the new synchro and installed it making sure the marks line up perfectly as they were before. I then installed the new plugs & wires. I will ashamedly say I got confused about the plug/wire numbers on cylinders 4/5! I could not remember which was which. So I looked at a diagram posted on this site and went with that.
So now here are the results.
The truck runs way better than it did before. For the most part there is no bucking or missing at the level previously. The truck, once I get going and get to 2500 rpm's runs much stronger and smoothly. Much more power at cruising speed.
But here's the caveat: There still is a uneven idle. I don't mean it rises or falls @ idle though it may do that slightly, but by "uneven" I mean to say that it is "lightly"rough or "lightly" misses.
When I take off in 1st gear the engine feels like it wants to do the bucking,missing thing but doesn't. It definitely has more power than before at those lower rpm's. And after I am in 2nd or 3rd if I let the rpm's drop below 2200 and then try to accelerate it will miss and buck ever so lightly for a second then strongly pull through the rpm's.
This is driving me nut's! Can anyone her give some ideas as to what to look at? Fuel? Some sensor? Any help is appreciated!
