my h22a seems to hesitae during acceleration between 2000 rpm and 3000 rpm by any chance would any one know wat could be wrong with my motor?!?!? ive tried cleaning the TB and EGR but that doesnt seem to work it idles a bit better but it didnt solve my hesitation problem!! HELP!

 

welcome to the 3k hesitation. as this time there are no positive 100% fixes. im about to try cleaning my egr ports see if that does it.

 

read my post and do the EGR test.
Thats what it is. h22 egrs are prone to it

Did you change your Plugs, Cap, Rotor, Wires? Try cleaning your IAC and PCV Valves too.

 

I have had two h22 swaps with the exact same issue, and found yesterday my timing was waaayyy off. I was told that after a T-belt change on the H22 it's really easy to have the exhaust cam gear off by one tooth. Either way, adjusted my dist to compensate and bewya.. we got power. Just a suggestion.. :

 

ive changed my spark plugs but not my cap or rotor or wires yet i still have the nology hot wires i dont know how long they last

 

whats ur EGR test? when i opened mines up it was filled with all this black gunk so i cleaned it out with as much as i can but i think i will need to open up my whole intake manifold n just clean everything n replace the gaskets. when i cleaned the EGR sol it seem to fun a bit better but i wasnt able to get deep enough inside the manifold

 

Change your Cap and Rotor and see if it still hesitates.

 

PLEASE unlike others
read this and follow it step by step.
start with the test, then move on to the cleaning.

IACV won't affect anything outside of IDLING (idle air control valve)

 

These cars can hesitate for a nuber of reasons.
EGR
Knock seonsor defective
Bad O2 sensor
improper timing
Worn fuel system
Worn ignition system
Worn engine

Check The simple ones 1st.
work you way down the list

-Be sure no CEL for knock or other
-Do the EGR test. if it fails fix it.
-Check/change your Cap rotor plugs.
-Test Coil and ICM
-Check timing
-Adjust valves
-Check fuel pressure
-Change fuel and air filter
-Seafoam
-Change O2 sensor
-Compression test

Those are the most simple and main reasons for Ping, misfire ect.

 

would you know how much is stock fuel psi for the dm h22a? i have the fuel guage on there rite now but i ahvent checked to see were its at.

 

fuel psi spec is something like 35-43

a guy at my auto tech school had this same problem and replaced damn near every part on the car. he hooked up an exhaust gas analyzer and proved it was intermittently going lean...anyways it ended up being a software problem in the ecu...put a new ecu in there and it went away

 

but that never happen to me before... but then i also when i use my A/C it idles smooth n goes great with out ne hesitation but then when i turn off the A/C thats when everything gets all crazy....sometimes it runs perfect sometimes it doesnt i havent figured out y it would do that....

 

I found the best way to cure this damn problem with h22's is to
seafoam
Change plugs
and tune on crome.
Its the only way, to cure this shyt for sure!!!
these motors are so sensitive to fuel and air mix.

 

any engine is sensitive to air/fuel mixture

the stock ecu should have no trouble running the car ok though.

and seafoam is crap I would never use that **** in my car.

OP: listen to s_vares, clean the egr ports, clean the tb, take out and clean your o2 sensor, maybe even get a new one, make sure your catalytic converter isn't clogged up.

The stock ecu should be able to run the car fine, other things need to be looked after first.

 

ive tried using the seafoam it helps for like a day or 2 then im back at square one rite now im running stright pipe and ive cleaned the EGR ports my idles a little bit better im going to change the cap n rotor n wires because i havent changed it ever sense i got the motor and do u guys think it could be caused by the dizzy coil to? i think ima change that out as well .....also by anychance would n e one know how to wire up the engine harness 02 senser plug not the one that is comming from the o2 but the one that is comming from the engine harness??? this idiot who wired it for me messed it up i think but i just wanna ask u pros n see if he did it rite.... THANKS

 

You are staring to **** me off, not trying to be rude.
DID YOU TEST YOUR EGR SYSTEM???
At idle remove the vac. line from the EGR and put it to straight vaccum (like your FPR or something) does your car stall???
If no your EGR is to blame.
TRY IT NOW

haha you need to chill, this is just the internet.

 

HAHAHAHA YEAH i tried it out it stalled

 

dude, hows the fuel pressure?

 

i dont know i cant check it cause i cant START MY CAR n e more!!!!!!!!!!!!!!!!! damn it i dont know WTF IS GOING ON!!!!!!! i just turned it on today to warm it up and all of a sudden it just shut off and ive been trying to get that thing to fire back up.... yesterday i heard some rattlin in my motor but then it was still running n now today i dont know ....im about to test out the IG coil and see it thats the cause.............

 

nvm i take that back the fuel psi is at about 40 a little bit under but my **** still wont start!!!!!

 

fuel, air spark and compression is all you need. you have good fuel pressure, so start with a compression test. also make sure your plugs cap rotor and wires are in good shape, now might be the time to replace them if its been a while.

 

Make sure you got the spark, fuel, then do a comp. test.
