I have a 93 SRV w/ a JDM h22a engine sitting @ about 90,000 kms. After the car warms up, I notice it gets bogged down in each gear @ about 3-4000 rpms. She accelerates fine upto this point then it just feels like something grabbed unto my rear bumper. I have changed: plugs, wires, disty cap and rotor, added good quality fuel injector cleaner a few times, high octane gas always, but still no luck. Could it be fuel issues?? The air filter looks ok. If anyone has had these symptoms or have any ideas, your input would be greatly appreciated. Thanx in advance.
I have a similar problem with my VTEC, but mine also bugs down at any rpm even when I give it full throttle. I checked my plugs and they were white, an indication the engine is running lean. This leads me to believe I'm not getting enought fuel. This could be due to one of the sensors no functioning properly or something is wrong with the fuel system. I have an appointment 31st to have my car checket.
check your rad, sometimes when the coolent level gets low the computer cause the car to hesitate , almost like it is running out of gas, if the coolent is low, top it up then disconnect the battery to re set the computer. wait about 15 minutes then hook the battery back up and it should run fine.

Hmm from what I have seen running over 92 (Like Ultra 94) is Harder to burn in a stock engine. Too many people I talk to in Toronto that use Ultra 94 seem to have this problem.
But if you're running 92 I don't know what it is.
What ECU? Maybe you have a V-AFC handy you could tune it out if something is funky with it.
Have you thought you to go to a muffler place and have your catalytic converter checked out.....that woudl have been the first thing i did .........sometimes thhey get clogged up and it really affects the acceleration.........cuz lack of air coming through..............and it just kinda puts a cork in all the exhaust coming out the manifold.........one way to tell on your own is to unhook the cat.from the header.....rig them both up ....ride around with thye header unhooked like around the block just to see if it solves the problem if it does..............you know you need a new cat.......
Thanx for all the suggestions guys, really appreciated. I topped up my rad fluid and reset the ecu. It cured the problem somewhat. I have noticed a stronger pickup, but it still feels like something grabs onto the rear bumber @ about 4000 rpms. I'll get the cat checked out soon and take it from there. Thanx again everyone. Could a clogged fuel filter be the cause??

I would imagine its a JDM ecu since it's running a JDM engine. I really shouldn't be so ignorant about my car. Sadly no $$$ for a V-AFC yet, just spent $1800 on rims and tires.....
i have the EXACT same symptoms that youre having with my jdm h22. dont worry about the cat because i have a brand new race cat on and there is nothing in there that can even get clogged, and my car still does it. i swapped distributors and the problem somewhat went away. im kind of puzzled also. ive changed out plugs and that didnt help. i need to do wires sometime soon also, the ones that came with my h22 are a little fugly. let me know if you find a cure.

Oh you have JDM too? That somewhat explains your better times...do you have the JDM LSD then?
Anyways, is it not possible that what you're feeling is the secondary intake runners opening at 4000? I know on every 4th gen I've been in there's a wrinkle at 4000 rpms, but usually it's more of a boost than a pull back...

Arrgh I KNEW IT!!! That makes your times sooo much better. My bud has JDM H22a with LSD in his 4ws and we run the same times...200 lbs difference! He has other mods...but man is he fast off the line

go ahead and list me your reasons for saying that jdm h22's are "sooo much" better than usdm's? this ought to be interesting

nope LSD is my main beef...I don't know of any other differences to the engines other than fuel mapping I suppose cause of different or lack of emissions laws...

...and slightly higher compression and if he is using the JDM tranny the gears are much shorter too.

ha, i don't belive the 'jdm h22a' hype. only noticible difference between the usdm h22a1-4, and jdm h22a is lsd and closer gear ratios. which is nice. other differences are minor.
