NASTY VIBRATION

2001 Mitsubishi Eclipse

Engine Performance problem
2001 Mitsubishi Eclipse 4 cyl Front Wheel Drive Automatic 137000 miles

Engine has a nasty vibration around 4000 or so rpm's. I can really feel it in my feet on the gas pedal. I've installed new NGK Iridium plugs, Bosh wires, timing belt with tensioner kit, crank and cam seals, water pump, shaft balancer belt and a new mass air flow sensor. No check engine light is on and no codes are being thrown. No vibrations when car was purchased until now.

Hi shark030267,

Most probably the balancer belts have not been installed in sync.
