EGR System in Rav4
Perhaps, some of you could help with my EGR problem in a 1996 Rav4 with 175,000 miles.
The EGR valve has been having both codes for stuck open and stuck closed.
An EGR modulator was installed Dec. 2010 when my front converter was replaced. The converter "blew" is how they described it and pressure had built up in the modulator causing it to "blow" too.
The check engine light first came on in the summer while I was traveling.
A shop checked the codes, I told them about the work in Dec. they checked the system, reset, drove, light came back on and reset again. They explained the system a little and said it is safe to drive.
It seemed to run fine so I didn't worry about it the last few months.
I needed a battery a few weeks ago. That shop checked everything over, cleared the codes, drove it etc. When the light came back on they told me the same thing. It's safe to drive.
I decided to return to the shop that did the work in Dec. 2010 as I had noticed in the recent cold that it sometimes seems to lose power as I am driving and stutters a little bit. When it does that, it feels like the gas pedal is harder to push in or resisting.
They have had it in the shop twice.
The first time they replaced the VSV. I spent $ 330 for parts and labor for them to replace the VSV.
The next day, the light was back on.
2nd time they cleaned, checked connections and hoses and put air through the system. They started and drove it several times.
Tonight, after picking it up I made 3 stops. On the way home after that, the light came back on.
I will be taking it back to them on Monday.
I printed your post and diagrams to take with me.
Any other information any of you could share would be greatly appreciated.
