Q: No power acceleration after I hit 20 mph

asked by on

Okay so I had a couple bad hose worn out with cracks I replaced all my vacuum hoses piece by piece so I didn't cross hose anything still having issues like it's not getting enough gas. it throws a code of 1409 and I was driving it I blew a hole in the EGR valve loud boom and then it sounded like a air hose or whatever lots of exhaust coming out of the side so I have replace the PVC valve, EGR sensor, EGR valve, EGR solenoid ,coils, 2 -02 sensors and spark plugs and I still have no power acceleration what do I need to possibly replace next

My car has 184000 miles.
My car has an automatic transmission.

Hi there. It is not too common to see an EGR valve have an issue such as this. It may be due to a large amount of back-pressure coming from the exhaust. This occurs when the catalytic converter is failing. I would typically test the exhaust first to see if this is the case. If that is fine and if there is good flow from the exhaust I would then scan the computer for codes to see if there are any known faults in the computer. If that is also fine then I would check the sensor readings to see if there is anything that does not look right. This symptom can also be caused by a valve timing issue, if there is too much wear in the timing belt causing the engine to lose power.

Consider requesting a YourMechanic certified technician come to your home or place of business in order to perform a loss of power inspection on your vehicle.
