hey guys so i have a problem.
last week i was driving and my car started running like a p.o.s. and the pgm-fi light came on so i read the code and it said it was the egr. so i took the egr off cleaned it out made sure the connections were good and put it back on. it ran great up until today. i started it this morning and it didnt want ot start at all. i started driving down the street and every time i stopped it would die immediately. i then took the egr back off re-cleaned it and the took off the pipe goin to the exhaust and cleaned that out too. it still runs horribly. i cant think of anything else to do. any advice would be helpful.

Replace the EGR gasket if you did not already. And take out the EGR port plugs in the intake manifold runners, clean them out and reinstall new caps.

where can i buy the port plugs?

When you say you "cleaned" the EGR, you just pulled the sensor and cleaned that?

You need to pull all the plugs and really clean everything out. Carb cleaner etc w/ a wire cloths hanger will do the trick. Plugs can be purchased at your local Honda dealership, they're not expensive at all - but you do need a slide hammer and a small drill bit or preferably the actual kit with the tap so you don't get metal shavings in the ports.


Is that the only code you were able to pull? I was unaware your car could just "shut down" from an EGR issue.

Yes I cleaned out the actual egr and the exhaust tube running to the manifold.. I also replaced the gasket..and ya the only code was for the egr... But I highly doubt the port plugs have ever been changed. As soon as I get some time I'll change them..

Not too sure what you mean by "exhaust tube" to the manifold.

The ports have to be cleaned well after removing the plugs, not just replaced.

If your plugs are brass* than it's never been done before. If they're silver and have a dip in them - it's been cleaned previously. How many miles are on your car?

my car has just about 180,000 miles on it and by exhaust tube i mean the metal pip running from just under the egr to the front exhaust manifold. but can someone please tell me where the heck the ports are located?

oh and by the way its a second gen with the 2.0

Ah, yeah my bad for not asking that first - I assumed you had a 5th gen. In that case i belive you have hoses going to the EGR? someone from the 2nd gen section should be of more help.

the new black box removal efi only - Honda Prelude Forum : Honda Prelude Forums EGR black box removal is all I can come up with - but I post it because it's got alot of pics to trace your hoses and check for any that are clogged. You may have to replace the EGR itself

ya i have one vacuum line running to the egr but its not clogged seeing as that was the first thing that i checked. thanx for the help ill re check the vacuum lines tomorrow.
