My car is starting but once you press on the gas it bogs out. Now I had someone look at it and they mentioned three things the throttle posiition sensor, map sensor, and the egr valve. The guy said that I would only need to change the throttle position sensor which I did have change but it is still doing the same thing. What else would be the cause of my car starting but when the the gas is pressed it bogs out

its a pain in the *** but it located on the right rear (pass. side) of the motor. it bolts to the cylinder head and runs up to the intake manifold

You have a plugged exhaust, replace the catylictic converter and find out what make it fail and plug, rich fuel mixture is most common cause of overheated burnt cat. The EGR is just a symtom of the plugged exhaust.

Unfortunately, both of these items are equally important and repairs can't normally be avoided by taking care of your car.

Your MAP (Mass Air Pressure) Sensor measures intake manifold vacuum pressure to help control the air and fuel mixture and timing. It contains a pressure-sensitive element that connects to an electronic circuit, generating a signal that changes with pressure changes in the manifold.

Your EGR (Exhaust Gas Recirculation) valve recirculates exhaust gases through the intake manifold to be burned again, cooling peak combustion temperature. Dilutes the air and fuel mixture to keep the nitrogen oxide emissions within breathable limits. And yes, it could very well be that the EGR solenoid that is causing the issue.

Both units effect your vehicle's fuel/air mixture. This is important because your vehicle running lean/rich can cause "snowball" problems. For example, a faulty EGR can cause the vehicle to run rich/lean. If not repaired, in time, the exhaust caused by the wrong rich/lean fuel mixture can damage the O2 sensors and/or catalytic converter.

If I had to pick, I'd start with your MAP Sensor. One guess I would have is that your MAP Sensor failed and made your vehicle start burning the wrong fuel/air mixture. Assuming I'm right, this could have damaged the EGR Valve. So, I see no reason to replace the EGR Valve alone, just so it too can be damaged by the poor fuel/air mixture caused by the still-faulty MAP Sensor. If your lucky, you may see the faulty EGR code disappear once your MAP Sensor is replaced.

Hope this helps and good luck!

I repair mine last summer,
It is on the exast port, left.
You have a tube attach to it, going in the Head Cover.
Easy to change. it cost me $105.00CND at the dealer

Good Luck
