Well I diagnosed my Check Engine Light and a number of things came up. So for those of you who knows a lot about our VQ engine, please help me with advice or any suggestions that can help.

First thing that came up was 1008: EVAP Canister Purge Volume Control Valve.
Second, 0303: Front Left Heated O2 Sensor.
3rd, 0304: Knock Sensor.
Lastly, 0606: Cylinder 3 Misfire.

How much is all of this going to cost to fix? Are any of these easy for DIY Mechanic? What's the best way to remedy these problems (Mods, Conversion, New Engine?) If costs are extremely high, I might consider salvaging the car. It's not like I want to because of so much work I've put into it. And I'm pretty sure that my car has other problems too. My 95 currently has 155k miles. Any suggestions please. Thank You.

I think the first one has to do something with gas tank cover (I got a brain fart so I forgot what it's called), check for codes, then if the O2 sensor is still there change it (sometimes O2 sensor make the knock sensor to go off), and the missfire is proabably a coil.

If you do it your self, and I was right about the first one, then it's going to be like $200 without the knock sensor, with knock sensor $300.

why shouldn't I replace the KS?
Thanks for the help guys but after reading upon the thread Jatan gave, I think I'm gonna take it to a mechanic. Depending on if some friends of mine can help me fix them. Thanks again.

knock sensors are a pain in the a$$ to replace ...

The knock sensor is usually triggered by other things. Just fix the other stuff and reset the CEL. Then a few days later, check for the hidden KS code.

well i took it in on friday and i didn't get it back yet because the mech said some parts were coming on on tue so i'm expecting it to be done by today or tomorrow. But anyway, how much should I be looking at to be charged? I fixed the cylinder, 02 sensor and the EVAP. Thanks

well i got my car back today and the car feels so much smoother. It was such a surprise driving it again. But too bad it's raining, I really wanted to punch it and see how well it goes. Well the price was I'm thinking overpriced but let me know wat u guys think. A little or a lot over? It came out to be $600 and he found another problem which is the A/C compressor but I was told by a friend that i didn't need to fix it unless I wanted A/C which I can care less about. Depending on how much it costs to repair, I mite fix it.

Now onto the knock sensor, should I go ahead and replace it myself or wait for the CEL to come on again and then replace it myself?

for the knock sensor, there will not be a CEl light, but pull your codes in a few weeks and then see if you get 0304.... if you do, prepare for the knock sensor install which is cheap(free with right tools)
and i found my knock sensor on ebay for 65 shipped brand new...


I just replaced mine and omg, its sooo awesome
