This is the first tour/Zetec I've owned - it seems to fall flat at about 3800 RPM - no power, and won't even get past 4500. Oh - manual trans, if that matters.
No codes, runs fine (no stumble etc.), new plugs, air filter, gas milage normal.
One thing I noticed is I can't run regular gas. It makes a horrible sound around 3800 - like it's a diesel engine. Alot better on 93 octane, but still no power.....
Can anyone help on this?
