happy new year.

so i got the dorman piece, (im surprised it comes with everything). in the instructions it says the egr tube must be replace is this mandatory or if the egr tube is good can i keep it?

the new egr is a redesigned one to help keep exhaust heat away from the plastic intake, and you should use it

Ok, the piece with two egr tubes right? 3/4 and 5/8

not sure what you are asking you have to take the old ones out and put the new ones in. they are like little metal cylinders with fluted end

Ah for some reason there's a missing word in my last post, but thanks that was what I was asking.

check engine lite
 

It threw a MAF sensor code. still don't know why, the injector was the prob. but sometimes you don't know about that obd 1 system. didn't have a reader, and was counting flashes. Sounds like the other guys have you on the right track.

well i will post the results after the installation of the upper intake and gaskets.

best thing i got to test the car at highspeed (on a safe track offcourse).

so im back from vacation and i can finally work on the impala.

i drove it today some miles to test it, and it worked fine, but when i parked it started to leak a lot of coolant from the upper intake (the old one, not the new dorman) so im going to tow it to the mechanic to put the new upper intake,

after that i checked the coolant levels ,including the radiator levels, and they are ok, the car crank and run normally.

here are some pics of the impala right now (with the old upper intake and the leak) (most of the coolant evaporated).

will upload new pics during and after the work is done.

just for precaution can i move the car to the mechanic "is far from my home some miles like 10 minutes at 40 mph" or should i tow it?

With it leaking that bad, I wouldn't even idle it if its leaking coolant that bad.
