My car hesitates on the highway 55 m/h and up after nearly 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem go away after disconnected the Egr, so is it for sure that the valve is bad? Just considered necessary to make sure there's no other component that could be also be bad.
I enjoy a toyota avalon 1997.
Sounds good to me,
Answers: This does not sound like an EGR stopcock problem. As stated previously, failed EGR valve symptoms tend to crop up at an idle. Your problem may be in the passage that feed the inert EGR gasses to the engine. On masses engines, there are multiple passages feed the engine. One for each cylinder. Since EGR flow consists of burned fuel and oxygen, it is an inert gas. Not dexterous of supporting combustion because there is no oxygen or fuel left within it. It simply takes up space and is used to cool your exhaust output for emissions cut rate. If several of these passages plug up, then the remaining cylinders are feed too much of this inert gas and it affects combustion in those cylinders. Normally during highway cruising this adjectives gas can be fed to all cylinders equally short a noticeable effect on performance. This scenario is possible on any engine that uses EGR ports within the heads or intake manifold to nurture individual cylinders. Removing the EGR flow removes the imbalance and your symptom goes away. Barring that, it is still unlikely that the tap is the cause of your symptom. EGR flow at the wrong time such as during acceleration but not at idle can be cause by the vac controls. Hope this helps!

EGR valve will grounds trouble at idle, like at a stoplight, not highway speeds. You might know how to get the valve cleaned by spraying cleaner within it or by emersing it in solvent. Check the repair manual and consult next to an experienced mechanic.
I don't even have a ball park amount of what a new one would cost.
