Default And the lean cylinder is ?

I read that #3 cylinder runs most lean. Which is #3 cylinder ? I'm plumbing an EGT gauge. Thanks

Yep. If you have a TBE or better yet, a TBE + headers the lean issue really goes away. And it's not so much that that cylinder runs lean as much as it has a higher EGT. Higher EGT does not mean it runs leaner necessarily.

If you want to know what cylinder is #3... Look at your engine (from infront of your car)... You will notice that one bank (side) is slightly closer to the front of the car... That side is the "Odd" # side... So then #3 must be the back one on that side... Does that help??

"Passenger side front" would be a much better description and take up a lot less space....

Hey.... Wanted to break it down n00b style... Plus, I wasn't sure of which side it was... Since I don't have a 4-cylinder

Hey greenmarine thanks for the info. Seems you being a non WRX owner had more accurate help than a previous try at help from a WRX owner. By your info its the rear passenger side. thanks again

Go to the wiring section, yesterday someone posted a split engine pic there with the cylinders marked for you. #3 though is the passenger side rear. PITA to get at, but it is the recommended one to put the EGt in.
That pic is a must have if you cant find it pm me your email and I will send it to you.

I thought the 'new school' of thought was to put the egt off of #4...

That is also what I had heard. THat's where I have mine at. Actually mine goes on the branch between #1 and #4, about 3 inches away from each.

I thought this was due to something with the fuel rails? Way back, old school Sport Compact Car, they showed some fuel rails for WRX's that fixed that problem.

I have seen a HELL of a lot of #4 failures. In fact, more #4s than #3s...

I think they are both lean. Actually I dont know that its lean, I think it may be a cooling issue
