I have an 84 camaro 305 v8... and my egr valve is sticking open. I went to autozone and it costs 62 bucks. Is a replacement necessary or is it possible for me to spray the thing up with carb cleaner and hope it "unsticks". Also in my stupidity I bought the wrong egr valve because i didnt look at the numbers and because it was 30 bucks cheaper. What will happen if I use this egr valve.. it seems to look like it would fit right on there but what would i be doing to my engine???
