Engine Mechanical problem
1999 Toyota Rav4 4 cyl All Wheel Drive Automatic 128000 miles
I had a check engine light for the EGR valve. I cleaned it and still had a light so I changed it. Still had a light so I took everything apart and clean it thoroughly. I cleaned and wired out the EGR vacuum modulator and sprayed cleaner down all the lines. My car would not start after that. Toyota dealer said I ruiened the EGR vac modulator. So I bought another one and replaced it. I have spent $350 dollars and my car is in my garage and will not start. It was running good when I pulled it in there. WHAT HAVE I DONE?
