jus me but i could be wrong, but if u checked everything and it still doesnt work, it jus sounds like ur intake cam is off a tooth or 2 since it hesitates at low rpm then jumps back up normally

This happened to a feller I know, **** nearly totaled his car. He had good ones but he thinks some little kids were messing with them around his car at some kind of family thing. Busted his windshield AND some, it happened on the freeway, so consider yourself lucky.

Back to your problem, I'm experiencing the same exact thing on my d15, right now my leading culprit is a vacuum leak. Had you done any work on the car around the time it started doing this, or did it just happen?

motor mounts might effect it too... mines are shot LOL...

bump. 60 days later.

I was having battery/alt trouble, i replaced both. They aren't the problem.

I have the timing set like this and the car runs (idles a little low, almost stalls when shifting)


it does the slight hesitation i've described in this thread.

when i set the timing normal to center, the car runs, idles even lower (barely seems to run) and seems rough like it's missing.

i'm going to go pull plugs, take pics of them. wires are new. will inspect cap and rotor and post pics. will check that all injectors are operating.

will try to borrow timing light to set timing perfectly/check it.

I'm like 99% sure timing is right w/TDC cuz i checked it 4 times.

look at this picture


A = arrow on oil pump on block
B = little nick on crankshaft pulley corresponds to oil pump arrow
C = other nick on crankshaft pulley corresponds to plastic gun-sight on plastic timing belt cover.....

AAAAND MY QUESTION
- the marks on the camshaft pulleys, are they straight up, like 90degrees from the street, or are they up in relation to the head angle.... cuz the motor isn't in the car perfectly level, it tilts forward. the difference is one tooth on the gears... could be it.

NegativeCamber

think we have the same Problem i changed cap wires pluggs even did straight pipe and seems only thing to do is injectors....

never rule somethin out til you know for sure.

there's always somethin you're overlookin.

BUMMMMMMP

i am having the same issue, have you checked your fpr? someone just told me it could be my problem. i don't know exactly how to check it.

I had a terrible hesitation problem. Still dont know if its fixed. My car did not have any power until about 3500 rpm. I was testing the fuel system today. How i tested my fpr was to remove the fuel rail with the injectors intact after i checked the timing.

What happened was i found that i have fuel pressure going thru the rail but when i turned the key to accessory.. it blew out a fuel injector. Swapped that injector with another one. It was the one on no3 and switched it with no4. The same one blew out. Switched no4 with no2. Blew out again.

Ordered 4 new fuel injectors from advance for $202 and will have them tomorrow. Hoping this solves most of my problem. Also having my valve cover sandblasted and powder coated deep red transparent. Cant wait to have the finished product and a non hesitant motor.

Also ordering a full exhaust from ebay to be cheap cause the owner before me had a crappy custom made exhaust with a glasspack and a pacesetter muffler that was not welded or clamped on. Just set on. It came off during a test drive and luckily it was on a dirt road or it would have done some major damage to my rear bumper.

dannggg i been looking forever for this thread.. or one like it lol my car been doin this for like over a month now. whats the best and easiest way to check the vacuum leak? that video was kinda iffy.. i dont have that stuff handy..

Corksil

just a followup.

cuz peeps are still havin problems.

my timing (mechanical) was off a tooth. fixed it, dizzy set back to center, car runs perfectly.

can't drive and feel the power of my new b20v yet, cuz i have an oil leak problem to fix first buuuuuutttt

TDC is not TOP dead center. I checked timing 4 times, always with a level, setting the up mark on cam gears STRAIGHT UP.

see the motor doesn't sit in the car level, it tilts forward on the mounts. TDC is TOP of the motor, tilted forward. so check you timing off the DECK OF THE HEAD, not straight up level vertical.

catch ma drift? best of luck

Kohen

check for a blown head gasket.
do a compression test.

Can the timing go off from just driving normal? Cus one morning I was driving and it was fine then later that day it started stuttering out of no where. Feels normal for the most part except when trying to press on the gas as im driving it doesnt pick up n go like it used to. Like just a slow response n then bogs as it tries to go. I was thinkin vacuum leak or maybe but I didnt feel anything, maybe fuel pressure regulator, the fuel filter is new n just installed. Possible for the fpr to go bad and cause this?

bumppp

Hey I know this post is kind a hold I was just wondering if you figured out the source of the problem I have a 2000 civic SI stock B 16 I just rebuilt the motor about 1000 miles ago and after the rebuild I know this that's very sluggish from 2000 to about 5000 RPMs there is no hesitation if I accelerate slowly but if I punch it say in first gear it almost like it's confused from 2000 to 5000 it almost feels like the clutch is slipping even though it's not it seems to gain power back at about 5000 of them again ivytech at 58 any insight would really help me thank you

Well it's an old thread, so I doubt any of these people are still cruising this forum.
Annnnd if you read the second page you would've found that OP's mechanical timing was 1 tooth off. Soooo maybe check your mechanical timing and then ignition timing.

Agreed on timing. I lost am engine on "timing it by ear." Either retarded or advanced it too much, and... *whooompf* it jumped time. Hmmm..directly related.

And that engine had a hard to read (for me) timing tooth, for the light...

Even if advancing time, don't do it by ear.

At night does you headlights dim at all while the hesitation happens??? if so then replace your ground cables. Just saying because i had a similar issue and that was my fix
