It is a possibility, but usually a warped driveshaft will start vibrate and only get worse as speed increases. We once had a Cobra owner complain of a vibration at 80 MPH, after finding a suitable patch of interstate that was relatively traffic free and completely cop free, we verified the vibration from 80 MPH on up.

Posted this in Drivetrain Tech, but maybe it's an issue with the 3.0 itself? As I accelerate, when my auto tranny shifts into what I believe is the bottom of the fourth gear, RIGHT on 70km/ph, I get a slight vibration, if I'm coasting at 70km/ph with the accelerator depressed to keep me at 70km/ph. The vibration is not evident at any other speeds, has nothing to do with my tires (rotated and inspected 2 days ago) My reading on here...

Thank you for your good info!! Btw, it does not appear to consume or lose any oil between changes, so I don't at this time think the valve is bad, but can a cracked hose cause a stumble between 1300 and 2300 rpm when at cruising speed, then stop and pick back up smoothly when more throttle is applied?

Those numbers are fine. Even a brand new engine can have some variance from cylinder to cylinder. Having a cylinder that is 8% off the mean on a used engine is perfectly normal.

Well, I've cleaned it. Have a spare so I can swap it out to see.

Here are the results of the mechanical diag done today. 2003 Ranger 3.0l flex. 54000 miles. Idle vacuum 18in. Compression cyl1 161 cyl2 156 cyl3 160 cyl4 160 cyl5 146 cyl6 165 Should I be concerned with Cylinder 5? It is in spec per my mechanic and he does not seem to be the least bit worried. Of course I am. I am having a complete mechanical and computer diagnostic done as a result of a catastrophic overheat resulting in head gaskets and...

Quote: Posted by Adam Baker Dimensionally it shouldn't be much different than a 3.0. I think you'd be fine w/ a 4.0. If I remember right, all the accessories fit between the frame rails, or very close, similar to the 3.0, so I think you'll be fine. sweet thanks man.... now the search begins!

Really? Another fuel Milage Thread?? Jeez, do a search. But I get 20 MPG With a SC.

Bought a 2004 White Lightning with 34,000 showing, almost factory stock. Borla exhaust, ARE bed cover with full Bedrug including under the cover. http://www.midwestcityford.com/vehic...RF07304CA65953 Ranger is now history. Thanks for any help you may have given me, but I give up on this POS ranger. I am now a renewed member of the National Lightning Owners Association (NLOC).

So i just picked up my 2nd ranger which is a splash 94 3.0 2wd 5spd, and i can get a COMPLETE 5speed tranny setup out of a 98 3.0 2wd truck for CHEAP, can anyone tell me if the 98 tranny will work with the 94 motor, and chassis?????? If not im gonna take my auto setup out of my 93 3.0 2wd truck and make the splash an auto i guess?
