2000 galant v6 3.0 egr/emission help.
Don't read this I'm an idiot. Read for entertainment purposes. Continue on further in the posts for my real problem...... :)
Hello.. I just got the above said galant for a very good price granted it needs some work but the only thing that I can't seem to figure out is the egr system. It seems like you need a rocket scientist to figure it out. I went to autozone to read the check engine light and he said it was the code for the egr and of course sold me an egr valve. After removing the old one it seemed to work okay but I put in the new one anyway figuring what the heck.
Three days later the check engine light is still on. They said if the computer detects that there is no problems over time the light would go out. Just like it takes time for the error to be there before the light comes on.
So after inspecting the vac hoses there seemed to be no vac at the egr valve at idol or revving the engine. The vac that goes to the egr comes from some round thingy and also branches down to something else. There was some vac at the round thingy, I removed it and attempted to blow and or suck through the inputs and it seems to work, didn't leak, though I don't quite know what it is for.
After searching around I found a site that said you could tweak the computer by adding a resistor inside so the computer will go to federal standards (which will ignore the egr) instead of CA standards but I think it was for a mirage. Well I can't find the site again but didn't know if it would work for the galant anyway. I'd have to pull the computer and compare it to the pics. AND I don't know if the state inspection place would pick up on it.
If anyone has some kind of diagram of the egr system with component descriptions would be helpfull. Diagnostic help would be better.
I also found another site with someone else that had what seemed to be the same problem but after reading all the posts at the end he gave up and sold the car.
I am good with mechanical and electrical stuff I have a meter and if needed I could dig out my 1964 tube type o-scope. But I need to know what to look for.
Thanks in advance.
Ignore this post I was an idiot when I wrote it last year. Now that I know that the egr ports were clogged. Please read on to MY next post..
egr problems, now new problems..
Time passes and my inspection sticker is almost due. The last information I had gathered from here suggested that the egr ports were clogged on my 2000 Galant 3.0. Of course I wait till the last minute, anyway.
Today I disassembled the intake, removing every bolt labeling it and where it came from, hoses etc. Brought the intake to a machine shop to be chemically cleaned, when done the fellow did say that there was a lot of 'mud' he removed from the egr ports. While I waited for the intake to be done I used carb cleaner to clean the intake ports on the engine, cleaned the pvc hose and the little pvc ports that go into the intake, replaced the pcv valve and because 3 of the spark plugs were under the intake I replaced them all (NGK BKR6E-11 (2756) numbers off of the package). Also found that I guess someone attempted to replace the plugs before, the 3 under the intake were a different model number (NGK PFR6G-11) than the 3 in the front that are easy to get to (NGK BKR6ES-11). Also the gap in the front ones was about .045-046 the ones under the manifold were .044. The ones I put in were .044. I also cleaned the faces and got a new gasket between the manifold I just got cleaned and the engine. After reassembly, everything went back together fine (disconnected the battery also). THE CAR WON'T START! Cranks over and when I let the key go I get a couple of puff, puffs 2 sometimes 3 (the sound, not smoke).
So, can anyone tell me what I messed up? Did the carb spray I sprayed into the intakes mess anything up? It was about 1-2 hrs before I got the intake back so I assumed the cleaner had evaporated by then. The oil is at the minimum level because I have been driving like a maniac lately but I never had oil problems before, will fill tomorrow, could the carb cleaner have gotten into the oil? The only other thing I can think of is the plug wires, they were a little tough to remove and I suppose I could have not seated them properly. Obviously I have to take everything apart again tomorrow to see what's wrong but I thought maybe after reading this someone might come up with a duh you did this wrong comment before I did that.
Thanks for reading and any help you can offer!
