So I have been trying to figure out WHY I have this hesitation problem on my H22. Well I was researching and might have come up with a solution.

I went outside and just unplugged my EGR...knowing I would throw a code. When I took it for a test drive I did infact throw a CEL BUT the hesitation was not there!!!

So basically what I am asking is to everyone that has had or has hesitation, try to take your car for a drive with the EGR unplugged. This is assuming that all timing and vaccums have been checked.

Let me know how it goes...

I have the hessitation problem. After we first cleaned out the EGR it was running good and then the light came back so we came to conclusion that it was my intake ports being clogged, but never got around to fixing them. Then a couple weeks later it started hesitating so I imagine it is from the EGR getting clogged back up as well as the intake ports. But then again I'm no mechanic, LoL.

 

with a 5th gen you cant block off the EGR because its OBD2...but with the 4th gens you should be able to block it off and just leave it plugged up so the ECU thinks its functioning normally.

 

ima go try and unplug mine and see if i feel the hesitation

So say I were to unplug it and it goes away. then what should I do since I can't block it off? Sorry if I am missing somethin here. Just trying to figure this out! Thanks.

you are 100% correct...with the 5th gen its going to throw a code no matter what you do...or at least that is what I am getting from my research.

 

well i unplugged it went drove around didnt feel ne hesitation, so i plugged it back in and didnt notice it either so...i dunno

 

whats hessitation? sorry im still a noob, is it when it jerks sometimes, if it is then i get that time to time somewhere around 2700-3000 rpms and its kind of jerky like not enough spark or fuel, i hope were talking of same thing and its on my 93 prelude

so whats the problem i never had it on my 98 prelude but i started having on my 93 prelude, and ill read through ur post later WhiteBB2 im at work right now well i saw something about EGR, and whever ever that located it? picture would be nice

 

Ok whitbb2 I just went out in the cold and disconnected the clip/sensor on my EGR drove around for about 5mins and it's still there. LoL. Looks like I may want to check out the knock sensor or maybe my manifold ports.

 

if you are looking a the motor...its right behind the Valve cover on the left.

 

what color is the plug? or its a tube?

 

there is only one s in hesitation.

get rid of those egrs.

I agree but I already disconnected it and still had the problem. So obviously I will continue to have it because that probably isn't the problem. But I do agree why they put EGR's on is beyond me.

 

Oh its not beyond me at all, they serve a perfectly good purpose for people who want a car with good gas mileage, they don't really do a whole lot for emissions which they claim to do.

 

i have an egr for sale if anyone is looking for one. its in mint/working condition. i have mine blocked off with a plate

just a basic tune up? i have replaces spark plugs, wires, cap, rotor, checked timing 2 times...none helped.

i unplugged the EGR and its running fine...the real test is tomorrow during the trip to work...usually theres hesitation and a rough start...we shall see...

 

what all sensors did you replace?

 

yup basic tune up with some extra odds n ends like i said. if ur makin ur car throw a code wouldnt it be goin into limp mode? i drove around for a year+ in limpmode bc of a code(vss n o2). the car runs like **** in limp mode, lower redline, no vtec, runs rich...y would u wanna do that??????????

there are some cels that have nothing to do with limp mode...Code 12 doesnt put the car into limp mode.
