OK the other day my car was running fine and then when I got off of the freeway it had a like sputter to it when your sitting at a light with it in gear or even in park it has a weird like hesitation to it. It only happens when either sitting at a light in gear or when idling it pretty much goes away after I get going but even when you first take off it has the hesistation also. I changed my cap, rotor, and wires about 6 months ago and just changed my plugs today cause they were pretty bad so I thought they were bad and well it still happens. Any suggestions?Oh and its the DX motor in my 91 CRX. Any help would be greatly appreciated!!

 

oxygen sensor i say.

 

I just replaced that a few months back also, But I guess it could have went bad.

 

Maybe a fuel filter. BTW did you get the pic's I sent?

 

I just changed the filter about 10 minutes ago and thats not it either.

And yeah I got the pics. Kind of wierd though I checked my emails at my brother in-laws house and the pics showed up and now they dont??

 

man i have the same problem on my 89 Si...but mine is both in and out of gear... like it sputters and sounds like it spits back...does yours do that? BUMP up top cus i need to know what it could be...

 

Yeah mine happens when its in or out of gear just worse when in gear though cause of the higher load on the engine. Also when Im first taking off it has the hesitation also. Its almost like it kind of has a miss but it doesnt cause everything else is fine. Any and all info welcome!! I dont want to replace like everything on this motor since I am going be swapping it out soon but I need it to run good in the main time until I get another car to drive while Im swapping it.

 

what exactly is the ideal idle? mine USUALLY idles at 500...and dips down sometimes when it sputters and "shoots" back...

 

check your pcv valve. im in the process of replacing mine bc of that same problem. it's cheap and easy.

 

This would be my best guess too. Although I couldnt remember if it was the EGR or PCV that caused that?

 

pcv

 

My car doesnt have an EGR system on it. Well for only a couple of bucks to change it I might as well but I changed it about 6 months ago along with everything else (cap, rotor, wires, and O2 sensor). But I might have an extra laying around might as well throw it in and see what happens.

 

Its late give me a break, ehh?

 

Well as of this post the plugs, fuel filter, and pcv have been changed the problem got a little better but its still not fixed. Any other ideas??

 

yeah it's time for the SI swap

 

No check engine light? Maybe the ignitor in the distributor is on it's way out... it won't throw a code.

 

OK we will do it when you come down Saturday.

 

So would that cause it just to happen when im first taking off or idling?

 

ok I'll bring the LOL
At least it would run right get anywhere with that yet???

 

Could it be something with the timing?

 

I thought about timing also...but it was running fine and now its not. Correct me if im wrong, but wont it drive crappy all the time if it skipped a tooth somehow?

-Jake, who pretty much figures old engines are gonna run crappy

 

OK well first no I havent figured out anything with it yet I will putts with it some more today. As for timing I was thinking that but like Jake said wouldnt it run crappy all the time?? I dont know??!! I guess try and mess with it some more.....

 

Hey, I was talking to Aaron on the way back and we came to the conclusion that it's going to be something really simple. Check all the connections and clean them up. Maybe water in gas or dirty injectors. BTW he is considering the z-24. TTYL

 

Maybe do you have a bad ground somewhere? Your fuel pump is worked by a ground kinda. The relay turns it on and off using a ground, sorry I don't know which one. Ignitor also a possibility as mentioned.

 

Yeah I was going to clean them all up tomorrow and dump in a bottle of injector cleaner and see if any of that helps. As for the gas I thought about that too cause it started to happen after I filled up at a gas and it was towards the end of that tank of gas but since then I have put in a few bottles of heat and also gas from a different station. Oh and that would be mint if he bought the Z24
