The demise of my 3.4L

[meissen]

Got a code, I don't know of anyone that's able to delete 3.4L codes, there's just no one that really can program 3.4s.

So I should take out the EGR completely? Where can I get a pipe plug? Where is the EGR valve? My car isn't running rough all the time, but it tends to jerk when I'm going less than like 25 mph, and it smooths out after that. My car sounds like yours did in the "before" video. Plus, I have the usual rattling heat shield problem on the catalytic convertor, maybe I should just have that welded when I take my car in to have the tailpipe bent back to it's original shape. My dad got electricity hooked up in the barn finally, so maybe I can get in there to use the welder and air compressor. Anything else I should check out?

Have you checked over on FTV6? There's got to be someone over there that knows where to have the 3.4 programmed. . . I'll ask about it later.

Well, while it's definitely not the best way to do it and I'm no mechanic, there's really no downside to taking out the EGR valve aside from the fact that your SES will be permanently on. Don't ask about parts or how to do it, Sean did it for me so I have no clue.

From what I've heard and looked around, it's a two fold problem. One, my 3.4L specifically is OBD-I, so that narrows down 90% of the programming software because it's not OBDII. Secondly, the fact that it's a 3.4L... there's no companies that I've ever heard of that will physically tune/program a 3.4L computer.

[93formulalt1]

I understand. . . Mine is also a 94 OBDI 3.4, as you know, so I'm in the same boat. My SES light is on all the time anyway, but no codes pop up when I run the scanner on it. I'll make sure to give the EGR delete a try, hopefully it works.

LOL, um, no, I don't see a lot of market for that, lol.

Yeah, some vehicles you can just get a block off plate, done it plenty of times. All the EGR does is take the positive pressure crankcase gas/air/atmosphere or whatever you wanna call it and put it through your intake. Hurts more than it helps, but that's how they get around emissions.

So you can probably just get a block off plate and take it out Nick. Probably, I dont' know for sure though.

yea there is nobody that can tune a 3.4l camaro that is why I wondered how he got rid of the code, but since he didn't nevermind then.

[meissen]

Yeah, if I remember correctly the EGR is just a pipe and then the EGR valve bolts to the block or something another, you could probably unbolt the EGR valve from the block, take a quarter or a penny or something that would cover that hole securely (make sure it's too big to get stuck in the EGR valve nor the block) and then bolt the EGR back on. If it runs well for 5 minutes or so, and you notice an improvement, then take the time to do it correctly and permanently.

Yep, other than the "something another" is the intake that's all you need to do, find something to test plug it with. It should be attached to the intake somwhere. And its more than likely vacuum activated so make sure to plug the vacuum hose after you remove it.

One time in a pinch I cut the side of a oil container in the shape of the base for a block off plate and siliconed it on. Worked great, held for a couple days till I could make a proper plate. I wouldn't recommend that unless there is no alternative however.

Just checked on FTV6, there IS a company that offers tuning for the 3.4 OBDI, problem being that it costs a little over $2,000 for the kit, and you have to have a laptop to do it. . .

you talking about the megasquirt system? If so it is cheaper than 2000 but kind of a pain to set up.

NM, seen that new post about that other system that is a stand alone system. What a crock being that high, you can get other stand alone systems for cheaper

All the EGR does is take the positive pressure crankcase gas/air/atmosphere or whatever you wanna call it and put it through your intake. Hurts more than it helps, but that's how they get around emissions.

EGR is Exhaust Gas Recirculation. It feeds exhaust from the exhaust port / manifold (depending on the design) and feeds it into the intake during low load times. This effectively reduces the displacement of the engine (the engine pulls in less fresh air) thereby increasing fuel mileage slightly, at the cost of carbon deposits in the intake.

The system youre thinking of which pulls crankcase pressure out is the PCV, Positive Crankcase Ventilation valve (thanks Jeff)

Isn't the PCV valve the Positive Crankcase Ventilation valve?

So youre flying over lake michigan in a canoe and one of the tires blows out, what do you do?

Yes it is! BTW you pwned me. Time to stop listening to dad's definitions.
