Question about 2007 Pontiac G5 Gt Coupe

Open Question

RPM's hanging problem

I have a Pontiac G5 Coupe GT 2007, it has 23,000 km (14,291 miles). I live in México (dealer told me even same cars would be diff here than in the US, don't know if that's even true)
While driving home from work, the RPMs would drop extremely slowly when trying to shift. I would push the clutch in, shift, and then I would have to wait about 10-15 seconds before the tach would drop enough to match rpms for the shift, the check engine light turned on, I took it to the dealear but they said they couldnt find the problem, that everything was fine with the car (rpms werent hanging anymore). They told me the code of the light was because of using the clutch hard or too much. I was like ?¿ because i knew I didnt.
The same day they gave me back the car, it was ok for 1 hr then it started doing it again and the check engine light turned on again.
Also my cruise control is not working anymore, I dont know if its related.

They already cleaned the throttle body, checked the TPS and the IACV and it doesn't look like a vacuum leak.

Any help would be really appreciated!
Thanks!!

SOURCE: no acceleration

I had the same problem with one exception. It would rev higher than 3500 but the higher it revved the more it bogged. I had the catalytic converter replaced. I thought I bought a new car. Acceleration is just like new. It was easy enough to test. My mechanic cut a hole in the exhaust pipe in front of the catalytic converter. It sounded like a truck but the acceleration difference was immediate. Easy diagnosis.

The car is hard to shift because the more you press on the accelerator the more the computer for the transmission won't let it shift. Which in turn causes the car to bog more sending more unburned fuel into the catalytic converter. Which in turn causes more carbon build up and more back pressure. Vicious cycle. It will only get worse.

My thermostat caused the entire problem. Thermostat was stuck open, engine never got to operating temp most days. Car burned rich. Bad gas mileage. A lot of unspent fuel being dumped into the converter. Probably have some underlying cause that needs to be addressed. Bad plugs, wires, coil, fuel filter.

Brassy noise coimg from exhaust when accelerating and power response delayed after shifting and is worse when the a/c is on. Might have to have catalytic converter replaced and was wondering if this is...


yes the cat is covered, but u have to prove the cat is bad, that means u must pay diagnostic time in the dealer to verify the cat has failed, if it is the cat they won't charge u if it proves the problem is not the cat they will charge u at least one hour labor, about $125 on average.

Have a 2007 Pontiac G5 and need to add power steering fluid.


its tricky. its behind the engine. If you pop the hood and you go to the left side, look behind the block and it chould be about half way down or so. You should see the cap for it. I think that was a horrible idea on pontiacs part. Happy motoring!
