Hi guys
i have 03 3.0 flex fuel with 100k

Ok had a error code misfire #5 cylinder mechanic just did the injectors so
I replaced coil pack, plugs an wires ran fine for 2 days on way to work last night engine light blinked felt loss of power so when i got to work i plugged my reader in an now error code for cylinder#4
I checked for loose wires all tight i know plugs all gaped right
I have searched the forums and i am a bit lost any suggestions where to go from here??
I have looked at the wiring going to the coil pack cant find anything wrong with it so i am thinking sensor??
any help would be greatly appreciated

ok on way home from work i baby-ed it had no problem felt no power loss or shaking when i got home plugged reader in there was no codes or errors. i checked everything again. it all looked ok
So took it for a drive got on the freeway on ramp see if it would do it again and when the RPM get above 3000 engine light flashes and i get the error.
Hope that helped some
Thanx Steve o

My dose the same think it 2006 ford ranger 3.0 I do not no what to about it

I have a 2004 ranger Edge w/3.0 at 110,000 miles. Just bought it last year w/about 100,000miles. Shortly after purchase, I started getting the cylinder misfire codes, multi cylinder misfire code & misfire v1000 revs. I then noticed a plug wires had been changed & previous owner claimed No Knowledge of MIL codes. The codes will not reset/clear for more than 10 miles. Runs fine on open road but in city traffic or sitting idle it will begin to misfire & ck eng light flashes (wanting to stall from stops) Rev eng to 1500 rpm helps eliminate the misfiring. I've heard of the TSB for this problem & that it is a manuf head alignment problem from the build. I'm lookin for money for another engine!

If you find anything out, please share!!!
