Lags till 3500 rpms!

[adams86lxi]

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

[bobafett]

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

[adams86lxi]

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!

[adams86lxi]

BTW: what mods did you have when you started to feel it go away. I have intake, exhaust, and msd blaster 2 coil!

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

[adams86lxi]

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

[Vinny]

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

[adams86lxi]

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.

[bobafett]

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

[accordlxi2.0]

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

[adams86lxi]

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?

[MrGlicko]

how new is your clutch?

[adams86lxi]

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?

[nswst8]

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

[adams86lxi]

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

[Volitech]

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]

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.

[MinuteRice]

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]

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

[Volitech]

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

[adams86lxi]

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

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

[Volitech]

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?

[danronian]

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).
