Hi everyone, newbie here.
Had timing chain job recently done..now im faced w car dying every now and then...looked under the hood and noticed the the harmonic balancer dancing a bit; is this the cause of the stalling or perhaps a different sensor?.
thanks much in advance

 

definitely not supposed to dance. could be the reason, any CEL?

 

Mechanic stated because of uneven bolt head is old gonna look wobbly.
Ran scan tool and i see p0451, p0446, p0455 and p0106..

 

Mechanic is full of it.
Could be any of the codes. Check fuse #64 under hood. Check the wires to the MAP sensor. Might have a bad EVAP vent valve.

 

Thank you donbrew. Will do just that and replace if needed👍👍

 

P0106 Manifold Absolute Pressure (MAP) Sensor Performance
P0446 Evaporative Emissions (EVAP) Vent System Performance
P0451 Fuel Tank Pressure (FTP) Sensor Performance
P0455 Evaporative Emission (EVAP) System Large Leak

 

He was to have installed a new bolt for the harmonic balancer, and torque it properly, the crankshaft pulley bolt should be initially torqued to 74 ft-lbsfollowed by an additional 125 degrees.

 

Uneven old bolt head ? Not even sure how that’s possible. But if the balancer wobbles, it’s really only 2 things it could be. A damaged balancer or a bent/damaged crank.

 

At 155k when I did my chains the harmonic balancer had separated.

HMMMM!

 

Your mechanic needs to go back to school or enroll for the first time.
