93 Lifgting running ruff
Hi all, I have a 93 Ford F-150 Lightning that I bought new.
It now has 170,000 miles on the clock and has never let me down...now for the problem.
When the engine is running @ idle in neutral or in gear the engine is shaking .
I replaced the plugs,cap and rotor with no change in the shaking.
The plugs that came out had 54,000 miles on them looked good.
With the engine running I pulled one plug wire at a time with no change in how the engine ran still shaking.
Its almost like the engine is out of balance.
What should I look at next??
Bad tank of gas?
Balancer sliped?
Thanks David
