Started to misfire, surging and vibrate at 30 MPH. Little gas and off we go running good.
Average mile per gallon is between 18 and 19 city … have not really take a road trip yet.
I have put in full tank 89 Octane to see if that helped. It did a little but still misfired, surging at 30 MPH but not as bad.
Problem is worse if going up a small hill at 30 MPH, vibration last longer and can feel the engine surging, missing but once up to a speed over 35 MPH and giving it gas. Problem stops and run great.
32,000 mile maintains new spark plug, tune up, wheel balance and rotated tires, replace all fluids, oil and lube.
Problem is still there… …and no better…
have the same problem?
