Do you have any mods, or is it truly stock as your profile says?

Truely stock, I think it may be tyhe timing is off.........anyone know how much it would cost to have a mech do the timing and a new belt??????

It could be something as simple as a bad O2 sensor.

How many miles on car?
Last time the O2 sensor was replaced?

 

[zachab242]

It has 142000 mile on it. Im not sure when the O2 was replaced. it make a whiney noise down in by the pulleys with the timing belt........im just concerned im gonna lose some valves, and i really dont wanna get ripped off by a mech i wanna know what i need done when i go to the mech... and I trust the opinion of ppl on here with good ratings.
