I went back to dealer two days ago, they told me there is a recall for 99 TL~

It's EQR Port, something for fuel tank~

does anyone know what is that or got recall?

 

EGR, not EQR.

There's a problem with the EGR port getting clogged. Send a PM to Kris for details -- fsttyms1.

 

It's not a recal, but a warranty extension.

If your Check Engine Light comes on and code P0401 in stored, Acura will clean the EGR ports and replace the EGR valve at no charge, up to 80,000 miles (if I recall correctly, ask your local dealer for the mileage specifics.)

 

I see it's EGR~

EGR (Exhaust Gas Recirculation)
The purpose of the EGR port is to feed exhaust gas from the exhaust system back into the intake air flow whenever the coolant temperature is high enough and the ported vacuum is also high (ie, not during startup and only during heavy loads or hard acceleration). This decreases the engine temperature, which in turn decreases the emission of harmful nitrous oxide (NOx) gases. Reduced temps will reduce pinging, which will in turn allow you to advance your timing farther for better power throughout most of the RPM range. By diluting your intake charge with exhaust gas, the EGR will reduce your peak horsepower at higher RPM's, but it will not adversely affect power under normal driving conditions. In fact, with the base ignition timing properly set, the EGR will allow for increased power at low- and mid-range RPM's. If you use the engine for drag racing, then disabling the EGR is probably a good idea. For any other use, you're better off making sure it works.

 

Wait, is there a way to disable the EGR in our cars?? Just curious. Never really thought about it.

 

you could if you wanted to i suppose

 

baisicl if you get the code p0401 you have to remove teh upper intake manifold and clean it out. it has very little to do with the egr valve it self. there are alot of little passages that get plugged with carbon in the intake and need to be cleaned out by hand. i havent had a issue with the egr valve itself, but i have had the ports clog twice (around 75k each thime)

 

How would I go about doing that??

Well, actually, first off, how much performance would suffer with EGR? In other words, how much do we have to gain by disabling EGR?
