Had a Ranger back in the day and had an opportunity to rescue one at a great price and I’m back in the fray!
I have an issue that I can’t seem to figure out.
Truck is a 2007 Ranger Sport with the 3.0/Automatic. 98,000 miles
Truck was sitting for 3-4 years and I bought at a great price.
All works as it should except for a shaky idle and a shudder in the 1500-1700 partial throttle area.
Maintenance items done:
New spark plugs- old plugs looked normal
New plug wires
New air filter
New fuel filter- It looked original and when I cut it open to inspect…it looked like a silt box in there!
NO check engine light NO codes
In running a scan on the fuel system, all looks normal EXCEPT for the LTFT on bank 2
Internet is telling me that it indicates a Lean condition and computer is compensating with more fuel.
LTFT on bank 2 was 18% and went higher with throttle- thought it might be O2 sensors so changed both upstream sensors on bank 1 and 2. LTFT dropped to 14% but problem persists. Original Affected bank 2 sensor had black soot on it while bank 1 looked normal..
I’ve done the carb spray/vacuum leak test and can’t seem to find a vacuum leak.
Only 2 areas I’m considering looking at are the upper/lower intake gaskets (leak?) or a faulty fuel injector.
Anyone had a similar problem and how was it solved???

Hey Gang...Larry etc. I apologize for not posting the solution here...I did follow up on another Ranger forum but dropped the ball here.
Turns out, my issue was not fuel related like I thought.
It was ignition
It was the COIL PACK. Changed that truck runs like a swiss watch now.
Hope that helps!
