ok heres the scoop, recently replaced my heads with 84 high outputs, they were free, and my old head gaskets were goin bad, anyways, i wound up having to put and 83 350 4 barrel intake on there too. It has a place for egr, but wont clear my iac valve on the tbi, so i used a block off plate and plugged the line. The question is can i drive like thise, how will the car run after its warmed up and realizes the egr isnt there? I have to drive the car this week and weekend before i can do anything about it, and have to go 200 miles to michigan, and want to know if the car will be ok to do that. thanx guys.

I think I would run a 180* t'stat and premo gas along with making sure the base timing is set at 0*. Now when you get a chance to play with the chip (or have someone else do it) to take the egr out of the system you can start putting more timing back into it and go back to using whaever grde gas you had been before.

Without the EGR, you will be running hotter combustion temps with the stock chip and mixture. I woudl defintealy retard the timing, and run better gas to reduce the detonation.

Pings are licke fingernails on the chalboard for me
heheh

 

I WOULD ALSO INVEST IN A COLDER SET OF PLUGS!!!

 

well i just need it to get through a couple days though before i can put in a spacer and buy an egr for that intake, the reason i wanted to know how it will do is because i have no money at all til the weekend, but am goin outa town, as long as it will do ok for 200 miles, i'll be happy. but thanx for the replies guys

 

Do not get colder plugs. The egr is not in operation very much anyways and if you remove it in the chip you will have no problems what so ever. If you do not, the computer will advance the timing thinking the egr is working and that is when you will have problems. A colder plug is not the solution.

 

a colder plug will help it to not detonate so yes it will help!!! also if you run nos you need colder plugs and for blowers... also did you know that if you use platinum tipped plugs with nos the tips can melt off!!! i have seen it several times and its ugly

 

Yes, a colder plug will help it from detonating. This is true, but like I said, the egr only functions during certain times. Most of the time you drive the car it is not even in operation. Thus, getting a colder plug will only allow the plug to not run hot enough and foul easily. This is why a colder plug is not the correct fix for the egr. The only real way to do it is to remove it in the chip. Plain and simple. Why bring up nitrous? We are talking about the egr, not NOSSSSSSSSSSSSSSS yo.

 

because it is interesting...

 

It'll throw a code every once in a while and you'll lose some power. Pull down your timing and you'll be ok.

 

Don't bother touching your timing. EGR is never in efect during power enrichment, just light cruising . I ran 6* advanced with out EGR and never had a bit off trouble using 89 octane. The only thing you might be abile to notice is your SES light coming on from time to time.

 

I DID notice pinging, and detonation. Even at a light cruise detonation is bad for the motor.

 

There is no way that could have happened if your knock senser is functioning, because your timing would be backed off before you could hear any detonation. And if it wasn't functioning the forced Knock test would fail and the ecm would back your timing off a whole bunch so that you couldn't detonate.

 

Heh, my knock sensor is working fine.

You may have had a different experience than me, but there is no reason for me to make this up.

My EGR was bad, I had a SES light and, I got pinging under light to moderate acceleration, and while cruising in O/D when I hit the gas before it shifted down.

I replaced the EGR, the pinging went away, and so did the SES light. Go figger.

When it comes down to it, it's your car stormr do what you feel comfortable with.

 

Why wait for the computer to change the timing when he could just do it himself and not have to worry about sensors failing?

 

Have a nice day!

 

completely off the subject but how did that B&M shift kit work out for you and can u explain what it did exactly for power and speed

 

i have a 1970 chevy pick up with a 350 and am not running and egr vavle of any kind. i do not run anything higher than 87 and did not back off the timing. you would be hard pressed to hear any kind of pinging or anything coming from my motor. the egr theory is a theory, but if you are computer controlled then you will either have to run it or burn a chip to eliminate it.
