i have been recently feeling a lag from 1000 rpms to 3500rpms and its kinda anoying. You can just feel the car lagging and as soon as you reach 3500 rpms its this instant burst of power. You can really tell when you floor the car in the first 2 gears. It feels like it dosent really want to speed up and as soon as it reaches 3500 rpms it feels great. I was thinking the problem is in the fuel system somewhere but i just replaced the fuel pump and fuel filter. Could it be the injectors?

BTW: i have a 86 lxi 5 speed :cool:

does this only happen when your car is cold?

mine used to do that. i would call it my vtec...

i adjusted my idle and got a few mods, and then i dont seem to notice it anymore

hmm ill have to check that out tommrow im not sure if it does it when its cold and warm its been cold hear lately so it hasent been driven in the warmth in a while. Did yours only do it in the cold? Yea, lol it does kinda feel like vtec lol! :cool:

My hatch was a dog until about 3500-4k then it was like a kick in the ass, ended up being the cam gear was off by quite a few teeth

it should be off any i just had all the belts changed about 2 weeks ago.

how longs it been lagging? Did was it doing it before you had your timing belt changed?

adams86lxi
02-06-2004, 07:38 PM
yea, it has been doing it since before the timming belt was changed its been doing it for a while now not sure how long though.

mine would only do it when the engine was cold, by the time the needle started moving the car had smooth acceleration....

check the air filter, mine's did it and it was the filter.

alright, im bumping this back up because i am still having the problem. Its not the filter its clean. It does it whether it is hot or cold outside. My dad said something like that on one of his old cars it would do something like that and it turned out it was his cat it needed to be replaced bad and was restricting exhaust flow. I have the stock cat to a dynomax super turbo muffler could this be it. I also for some reason think its in the fuel system, like one of the injectors are fouling or something how would i know if a injector is fouling out, and could this be it?

how new is your clutch?

adams86lxi
02-20-2004, 04:44 PM
its farily new, had it changed about a year ago but its just now being drove alot. BUT my clutch cable is stretched out and im hoping to change it real soon because it has made my clutch feel like its older than it really is and i have the adjustment all the way out. on cold days it will feel like it dosent want to come up off the floor at all and has actually gotten stuck to the floor a few times! I have talked to the mechanic about it and he said it was just a streched out cable. Im going to change it soon.

BTW:MrGlicko are you saying this could cause my lagging problem some how?

When I had a pacesetter on I noticed it more than without the performance exhaust, sounds like your keeping up with your maintenance by sometimes we overlook the O2 sensors sounds like your building up some back pressure, so I would have to agree along the lines with your Dad.
Hope this Helps, LOL

so you think it could be the cat? The 02 sensor i replaced about 2 months ago. :cool:

Volitech
02-20-2004, 11:09 PM
I have that very same problem and all the same up grades you mentioned I repaced both o2 sensors and everything else i can think of except the cat..
Does anyone know if who makes a high flow cat for our cars?

bobafett
02-20-2004, 11:25 PM
u can get a weld in cat and it doesnt matter who makes it. but i would go with a 2.5" weld in cat. shit for that matter u could get a bolt on honda cat and cut off the flanges and weld it on, whatever u can find thats cheaper.

high flow cats help out a bit, it was a noticable gain.

pace setter makes some but i dont know for how much

MrGlicko

yea i had the same problem but when i changed my clutch it went away. It might have been a fluke. It couldnt have been the cat, I don't have one.

adams86lxi
02-21-2004, 04:32 PM
alright, we all agree its probbally in the cat that is giving us this massive lag in our accord. Now im looking for a direct bolt in wheir the old one is without having to cut or anything.

pacesetter= too much
ebay=no direct fits
random technologies=too much, BUT i was looking at them and have noticed that the 86-89 accord ones have the same model number as the 90-91 accord ones but the 92-93 have a different one, Integra 1.6L 86-87 has the same part number and Prelude 2.0L 85-91 all have the same model number

this must mean we can interchange them! what does everyone else think :cool:

02-21-2004, 05:38 PM
Ok I still think my cat needs to be replaced but today I was out driving and I noticed my clutch was starting to slip just alittle at low rpm!!!
So I think I'm gonna get ahold of Kmod and get a ACT/ClutchNet Six Puck
if he has one available

O, and here is the website i was comparing part numbers with http://www.lightningmotorsports.com/random_technology.htm :cool:

My car lagged because the vacumn advance was shot try to check it thismigth cause a lag.

So did you have to replace the whole distributer or what?

I have the same lag and I have a new distributer and timing belt. I also have kept up with all maintenence items except adjusting the valves. I think it is that or the cat (since mine is 160K mi. old).

I just had the valves done and it made no difference in the lag!
I'm gonna try the cat and see what happens!

i just picked up some exhaust pipe and im hopefully going to make a test pipe to go in place of the cat this weekend. While im down their im going to also weld in a piece of pipe wheir the resonator is, so if i get it done this weekend ill tell you guys if it helped at all! My car is also starting to sputter around corners when i get back on the gas so i hope all this will fix it! :cool:

adams86lxi
03-06-2004, 07:21 PM
alright, i removed the cat and the resonator, and replaced it with a strait threw pipe and i think the major lag i used to have all the way up to 3500 rpms is basically gone (i think) i havent driven it much so i will tell you more on monday or when i drive it again. I seems to run alot better though. I still dont think my car is running at its full potential but close. The only thing i did notice was with the strait threw exhaust, it now makes my dynomax super turbo muffler sound like a fart cannon IMO! :cool:

adams86lxi
03-08-2004, 10:59 PM
alright ive driven it alot now and it seems as if the lag is still their. But as soon as i pass 3500 rpms its way more powerful without the cat and resonator! :cool:

BTW:johnny o, i was kinda thinking the vacuum advance could be it to. Is it easy to swap with another vacuum advance or do you have to replace the whole distributer too because i was thinking of getting one out of the junk yard this weekend and swaping to it to see if that helps. It looks as if you would just take the 2 screws that hold it into place and pull it out and put the other one in is it that easy? THANKS! :cool:

launch at 4k and slip the clutch to keep from smoking the tires then. if you shift at 6200 you should pop back into gear above the lag.

same happend to me... but it was cuz the clutch pedal was to high so i adjusted the clutch cable and now it grabs and goes.

Volitech

Iv'e just put on a new high flow cat and I still have the lag! I think it's caused from the rings being wore!

I have fixed my lag problem completely!!! And all it needed was new o2 sensors! I went all out and got the bosch wideband sensor and it ran perfect after that!

adams86lxi
05-03-2004, 02:26 PM
hmm, this is old! lol i now have gotten rid of the lag completly. Partly becuase i now have a b20a in my accord LOL, I have figured out though that it wasnt the vaccum advance i changed that on my old motor and it didnt help. Volitech, thats cool that you found the problem. I had a brand new o2 sensor in my car, makes me wonder if it was faulty. hmm.

Had the same Problem Last year (lag below 3500....then takes off)
it was bad connection on 02 sensor

05-20-2004, 08:14 PM
hmm..i had this problem in my white 3gee and i just bought a new silver one and it just started doing this. in the old car it was the O2 sensors, hopefully its the same problem with the new one.

Could you possibly give me the part numbers on the bosch wideband o2 sensors, i tried to get some o2 sensors and the auto place i went to looked at me like im an idiot, which may be true but still....

well i have the same issue and my o2 sensor and af meter read off the charts lean and as soon as it starts to run a little better the a/f meter jumps to nearly stoic... i think the computer runs the engine leaned out until it absolutely needs more fuel..

had the same problem, fixed today. It was timing. My flywheel tdc and my camgear marks were lined up. I read somewhere on the internet that some early hondas that have had a timing belt replacement were turning out to be over-advanced. I can see why because the book says to do it that way! I backed my cam-gear off one tooth and she now hauls ass at all rpm's. Sweet! Hope my mpg's get better now.
