EGR Code

Could be that the EGR is stuck open. Either way, I'd replace it.

 

get the car started and the whole car shaking like an earthquake?

thx for reply. how much gona run me for replace it? is that somethings can be cleans fix or need to replace it?

 

I'm not sure about the price.

Does the car feel like it's going to stall at idle? Does it return to normal when you start driving?

 

no it not normal. it did not stay idle and would shut off but then i gassed. i have kept my foot on the gas at all time. held it at 2-3k rpm so it would shut off while driving.

 

^wouldnt

any idea guy???

 

Probably the EGR stuck open. Could be the TCC stuck on, but I think a different MIL would come on.

The EGR should be off/closed during idle but the car should be fine at cruising with the engine warm.

 

Yeah, I'd go first with a "stuck open" EGR valve. Pop it off and check it. Could have some crap keeping it stuck open. May be as simple as blowing it out with compressed air. See this thread:

when check engine light on. i did drove about an hour back and force from acuradealer. unfortunately acuradealer close on sunday. an hour driving engine should warm up but the car stills shaking badly. i remembered check engine light came on when i hit a small pothole at speeds 60 mile per hour. both my front wheels slammed hard and that when im notic my steering wheel abit off center. at this point i dont know wht to do. any suggesting wht i should do? sorry my bad english.

thx

 

thx nfnsquared for reply. that imfo u post make me so happy hehe.

so any DIY on how to pop EGR valve off and check/clean it?

dose any1 done blowing it out with compressed air before? that sound like a good idea.

 

Here's the service manual scan.

 

Sorry to bring this thread back up.

The service manual scan link isn't working anymore. Can a moderator add a new link?

Thanks!

 

It's very easy to replace. No need for a manual. There's only 2 nuts holding it on

 

Where is the egr at exactly? Having difficulty finding it.
