Hi,

I've recently had the entire timing chain, tensioners etc replaced under warranty after the car would rattle when idle, drop on revs, and had some starting hesitation.

Today when I started the car in the morning, I get out of the garage, accelerate and the car started behaving as if it had air in the fuel lines. It would cough extremely violently.

It stopped and I decided to drive it to church a mile away from my house. Then, when reversing into a spot, I get this loud wooing sound from front right corner of the car... No idea what that was...

Also, whenever I depress the clutch and the car is warm, it will squeak big time. Although, the noise is not coming from the clutch pedal, but the transmission housing. Dealer heard it but they said it was normal... I feel like it's the throw out bearing.

Any suggestions?

Thanks!

 

If hesitation happens during acceleration including jerky acceleration! My guess is the timing chain is being installed a little misplaced and what that does is when the valves need to be closed completely for the combustion to happen they stay slightly open and the combustion depends on which valve has the problem can spread to intake or exhaust manifold, that's when you hear coughing sound. Your ECU should already have recorded a misfire code, take it back to dealer and make them to fix it.

This actually happend to one of my cars when they changed the timing belt.
