My new cd5 has the classic signs of a clogged egr..Hesitation between 1500-2800 rpm... Well, I cleaned that well today(it really wasnt that bad), also changed plugs, cap and rotor. Anything else that might be causing this hesitation? Wires maybe? they look fine.. It has 138,000 miles and its a 5 speed...thanks.

 

did you clean egr valve and intake egr passages?

 

this is what I did.. http://home.comcast.net/~em-engineering/T2T013.pdf
Is there more to it than this?

 

now that you mention it, i get the same thing in second gear of my automatic. I just changed the wires, rotor, cap, and plugs (iridium, which may have caused a drop in mileage???)

 

yeah that's it.

run some FI and intake cleaner through the engine as well

 

The kind you dump in the gas tank? Done a few bottles of that as well....

 

Try the lucas lube stuff for the fuel system.

It's a little different from most fuel cleaning products and people that know cars a little better seem to like it. You may not need it but listen to YeuEmMaiMai.

 

might want to use bottled stuff that they introduce through vaccum line on intake.......

 

Like seafoam? I was thinking about doing the seafoam in the intake and the gas tank.

 

any developments??

 

how do i remve the fuel rail? all the small hoses are hard to take off i dont want to damage them. whats the easiest way to remove them

i dont know

 

just twist them off and kinda push also on the ends. If its stuck bad its ok to insert something that isn't sharp and kinda pry it off... they are pretty flexible.

 

when cleaning your egr ports ect, did you have to change any gaskets?

im going to try to do it this weekend, anyone know?

 

there really isnt any gaskets to change. theres one but its like hard plastic and it should be fine

 

Change the o-rings on the end of the injectors before putting them back in the fuel rail. I got all 4 from the dealer for like 12 bucks.

I cleaned my ports and still have the same issues. Also seafoamed my engine, ran lucas lube through the gas tank, and cleaned the manifold.. Im thinking of blocking off the egr with a plate to see if that solves my problems so I can narrow it down to the egr system.

 

i think the problem with my car is that the egr is stuck open half ways. i disconected the lift solenoid but i still have the hesitation i might just buy a new egr valve

 

So would disconecting the lift solenoid give the same results as the port blocking plate?

 

im not sure what u mean. technically the egr valve should not open at all if the lift solenoid is disconected because it is electricly (spelling?) controlled. So if u disconect the lift soleoid and ur problem goes away then i would suppose u have a bad egr valve
