engine studder

[bkennya]

OK, so I'm getting a studder while accelerating generally in third gear but it is happening throughout the range except in idle. It just loses a bunch of power but doesn't ever stop. It does a lurching motion and if I let off the gas and then put it back down it seems to go for a bit. It always starts just fine.

This being said the following have all just been done in an attempt to fix it. Coil, Plugs, cap, rotar, valve adjust, fuel filter, clean throtle body.

I did get the engine light twice for two minutes last week but nothing lately.

What do I have here? Please help.

My girlfriends 96 accord started to do that, but the check engine light also came on. I found that it was just a misfire, You would start to accelerate, then it would kina sputter and loose power. i changer the cap, rotor, wire, plugs, egr. Nothing fixed it.Turns out it was the EGR rail itself. it just got cloged. 2 hours later and it ran like new.hope that helps..

Oh yeah, if your engine light flashes, its most likely a missfire

Is the "rail" the same as the valve or am I off?


how did you unclog it? Or did you just go for a new one?

i THINK THERE WAS A DIY on how to unclog the egr ports. not sure though. anyways, at light throttle if you feel a slight bog, then it may be you ports and your egr valve. get another opinion though. good luck.

the "Rail" is what the egr bolts on to.I just use screwdriver and kind of gentile touch to scrape off the carbon build-up. then a small wire brush to get as much as i could. Yeah dayaaj has a good point, get a second opinion befor you dig into it. I had to get it diagnosed befor i had a clue to look at the rail

....The EGR bolts onto the intake manifold... Anyway a CEL doesnt always mean misfire...OBD2 cars have that code because they are more sensitive. OBD1 dont have a misfire code as I recall. Anyway you can feel the misfire so it doesnt matter. Clean out the ports has hondaay said. That will cause a low rpm bog or studder. Clean it out with carb cleaner and an unused brush/wire brush whatever and let us know how it goes. (i used a dremel for mine.

So did you clean out each of the ports on the rail or just at the valve itself?

You use a vacuum to extract the debris?

[NAiL05]

The ports are NOT on a rail. The only rail there is the fuel rail and a plastic clip deal behind it holding in the wiring. THE EGR AND PORTS ITSELF ARE ON THE INTAKE MANIFOLD. You use carb cleaner and a brush. The debris will burn off in the combustion chamber.

to tell you honostly, I believe you have to drill out the four openings and Honda sells a kit for the hole to be blocked off after you clean it. correct me if I am wrong guys.

[NAiL05]

Honda sells the kit but you dont have to drill it all the way out. Honda has the bit in the kit. You just need the slide hammer to pull it out. Its better to reuse the ones you got honestly. Just drill it in a bit take a slide hammer and pop them out.

It wierd how youll have a problem and you just come onto the site and get some answers. Maybe. Its like midnight, but im gonna go out there and try cleaning that rail. I replaced the valve, actually ive replaced tons of crap. Im sick of nickel and diming this thing to death. I havent broke down and taken it to a stealership....yet

[jhondayaaj]

why take it to a dealership when you have us?? there are many honda techs and people that work in parts dep. who goes on this forum like me for example. also, there are many members out there that are not honda techs and knows a lot about our cars. good luck though.

never resort going to a dealership. you are just admitting defeat. dont let the cb7 hate. love it love it and it will eventually comeback. always come to everyone here. a lot of people are very knowledgeable and some are not. but by your car trouble the experienced ones can help and the less experienced ones can learn.

i learn way too much.
