rpm needle jumpin while driving

ill keep it short and sweet. iv had this 1994 prelude f22a for only 2 weeks.

noticed this the other day when i was driving the car.. im driving and im watching my needle fling up to 3-4k rpms while im driving. however i did not notice any affect in the performance.... that was then, now im noticing that its actually affecting the cars performance. today as i was "steady mobbin", the rpm needle starts doin it little dance again and im like huh, ok you wanna dance, so out of curiosity i start ****in with the pedal, giving it extra gas off and on to see what happens. i put my foot in it and the car falls on its face a couple times. im like wtf? so basically its like the cars rpm neelde is immediately hitting higher rpms, and the engines pull seems to be slipping or cutting off.. so whos got the magical response for me today? lol hopefully i explained it all ok. btw, the car idles fine, maybe a lil low, lil ruff but nothing to bad. i will be cleaning the iacv and fitv in the future though as the car has 290k miles on it. you guys think maybe the distributor or something? idk man, its my first honda so...

Re: rpm needle jumpin while driving

My first response would be to check the distributor and then the VSS.

Re: rpm needle jumpin while driving

my dad just bought a distributor cap and wires. idk if i need the whole distributor but he got what he got so i can only do that for now. idk if just wires and a cap will fix it (kinda doubt it) but we'l see i guess

Re: rpm needle jumpin while driving

either vss, vss wiring, or ignitor pack inside the distributor.

I dont think its that because if that goes bad there would not be any power.

To the OP:
This is the other side of the distributor. That green wire is what reads your RPM's. Something in there is crapping out on you so you are better off replacing the whole thing

in all my experiences with civics/integras, (i say civics/integras is because im still sort of new to the f/h series engines and their different ways like external coil) if the car still runs but the tach bounces around erratically, its the ignitor pack or a connection to one of the wires going to the ignitor pack.

im not stating that thats 100% whats wrong, but buying an $80 ignitor pack or getting one from a different used distributor is cheaper than buying a whole new distributor.

when the ignitor packs start to go faulty or has a loose wire, the tach bounces around and the car will still start and run fine most of the time.

this basically is the case, the car will start fine, and will run fine, but when the thing starts doin its thing the cars response will actually cut off momentarily and ****. so idk i almost think it might be the distributor. just seems like it should be the distributor lol. but hey lemme ask this, if it is the distributor, if i got the car a diagnostic would a code show for the distributor? im pissed cus i spent my summer break installing a system in this car and i was almost finished but now i get to deal with this lol.

is your check engine light on? if it is not, it is not throwing a code. if it is, find out what code the car is running and then have that replaced.

but in all my experiences, when an ignitor pack starts to go bad, it does not throw an engine code.

also, the ignitor pack is inside the distributor. so if you replace the distributor, you also replace the ignitor pack.

Re: rpm needle jumpin while driving

changed the fuel filter. car runs a LOT stronger now. car has a bit of a low idle, somewhat rough. this is nothing new though. dad put a new dizzy on but ended up breaking the teeth on the end as well as put it in wrong. so we now have another one coming. hopefully this will kick the whole "****ed up rpm needle" shiz in the butt. im tryin to get this thing good to go so i can finally start dialing in my audio system. but ok thats the latest on the pray-lube

fuel filter has nothing to do with an electrical component, so no.

no.

the cooler weather youre driving in has temporarily masked the issue.

further explaination....
electrical components when they get too hot can cut in and out or completely die. since your under the hood temperatures are less, everything temperature wise under you hood is cooler. which also means all youre electrical components are running cooler, and if they were overheating, they may not be currently.

or it could be something like you had a loose wire and you hit a bump causing the loose wire to have a better connection now. but if this is the case, you hit another bump and the tach will start bouncing around again.

was kind of what i meant when i said it fixed itself. But anyways i dont expect the issue to be fixed. for now its not doing it hardly ever. in fact it hasnt done it but maybe twice since the fuel filter.. im not dumb, i dont think the filter fixed it. but its not doing it anymore so... and a new distributor is on the way, and i doubt its the dizzy..

Re: rpm needle jumpin while driving

it was the coil. bad coil causing the distributors to act up. fixed that problem. now we got spark plug wires popping out. idk why its doin it though.. at first i i thought it was dying from fuel but what was happening was the engine was only running off two cylinders..
