Brand new Ranger- rough engine?
Hey everyone- I've got 700 miles on my 2004 Ranger XLT 4x2 Supercab manual transmission with the 3.0 V6 and I'm already wishing I had the 4.0. The engine doesn't feel 'smooth' at all- definitely not like a brand new car should feel like. Does it get better after the break-in? Also, I've heard that I should get the oil changed a few times during the first 1500 miles or so is this true?

Deffinatly change the break-in oil.The best way to set the DRIVE CYCLES in the PCM is to use the STEADY FOOT method.excellorate steadly and dont floor it,while driving,hold it at a constant speed,dont speep up and slow down alot.It takes like 40 cycles to set it to your driving paterns,(start,drive,let cool )Also try excellorating from 20 to 50 at 3/4 throttle then coasting down to 20 and do this 3 times in a ROW.There are about 10 other things like this to do but I cant find the post for them.It will eventually learn on its own it will just take some time.

Rainan, I bought a new 2002 Ranger with the 3.0 and automatic. The idle was rough, but the roughness either went away or was not noticeable at road speed. I took it back to the dealer who told me "they all run like that". I didn't believe them, but had contacts at Ford dyno lab. They checked it out and gave me an answer: Ford eliminated the EGR valve on this engine by changing the cam profile. The result was a rougher idle, but no EGR valve. I guess I believe them. If a different cam grind can eliminate the EGR valve, I guess it could be considered an improvement. Knowing this makes me feel better about the rough idle. However, I think the roughness is permanent and annoying. At least it is not a symptom of something going bad. (Mine is still idling rough after 3 years and 22,000 miles.
