i have a 93 h22a JDM and for sumreason this start happening, when im in vtec i hear a slaping noise which sounds like my timming belt or my ALT belt is slaping around. Before i never had this problem. when i hear that noise vtec starts to cut off HELP!!!!!!!!

 

could be your timing belt slapping on your timing covers...could be a sign of auto tensioner failure, i reccommend you check it out before any serious damage to your engine occurs...

 

fix that asap otherwise you'll be doing another h22 swap because honda engines are interference type and valves will bend when that belt brakes

 

Pull off both accessories drive belts and start the engine. With an educated ear standing on the side, rev the engine and determine if the noise is still apparent. You should get a better idea without everything else contributing to the din.
If the noise stopped, so much the better - check out both the belts and the accessories mounts. Something may have come adrift.
If you've still got a noise from the t/belt area, you've a critical condition which requires immediate attention.
I think your VTec issue is unrelated to the belt slapping noise. More than likely a clogged up VTec solenoid or low oil pressure.

oh alrite cool i'll check that out today thanks guys i'll post up when i finshing working on it. THANKS GUYS

 

it still sounds like its slapping around but ice change the hydro tensioner timing belt n the balancer belt but my vtec still cuts off..... im not sure if its the vtec it self but i have another ecu i can try out maybe i have a bad ecu

 

VTEC YO!

 

how do you know that vtec "cuts out" ?? do you have a vafc or vtec light somewhere, or are you using the " yo it doesnt sound all cool and ****" diagnosis?

 

i can feel it cutting off.....lets say it kicks then once i hear it cut out it just starts to lag then when i pull over to read the CEL light it reads VTEC PRESSURE SWITCH and i dont know i have enoguh oil........ im going to try useing another ECU and see if that helps but have any ideas what can cause that

 

it's not the ecu. you either have a faulty oil pump, not enough oil, or you need to replace the pressure switch. i had to replace mine, you can get them used for like 40 bux on your motor. goto a junkyard they will usually let you have them for like 5-10 bux.

 

i went to the junk yard bought my self the vtec pressure switch for 5 buxs i think he didnt know wat it was but yah.. i slap it on let my kar warm up, check my oil check my belts. Once it fully warms up i take it to the streets it kicks fine then i hit the freeway thats when it starts to cut out agian..... i dont know wats wrong wit this motor its JDM haha what year is ur car n how did u set up ur h22?

 

well, if you're getting codes than check the wiring, there might be a short somewhere, and try another ecu. there's gotta be someone else in CA w/ an h22 ecu or a p28 that you can slap a h22 rom onto.it could be oil pressure as well. make sure that the ports for the vtec solenoid are clean as can be, no gunk and crap clogigng them. i had to replace the entire vtec assembly, plunger, sensor and all for it to work right.

 

ive changed it to another ecu its a 96 p13 but now im getting misfire codes 71, 72, 73, 74 i duno if i needed to change my injectors or my dist. like wat the other forms said but this ecu vtec kiks fine... i just dont know if i have bad ecus or im just doing sumthing wrong cas its misfiring, i mean the kar runs fine until when i keep on driving it the CEL blinks n thats when i check the CEL out n it tells me misfireing ima try to turn up my dist n advance my timming see if that works.

whoa, dont up the timing on the dizzy without a timing gun, otherwise you could do some major damage..

 

haha its kool my friend let me use his timming gun but thanks for the heads up... it still misfires... so ive cahnged the ecu out n put in the obd1 p13 with the jumper, i took it out for a spin vtec kiks but then vtec still cuts out. its like it works for the first run but then if i punch it agian it will jus cut off. it happens randomly

 

are you sure you have the correct oil level? keeps sounding like that, or you have some bad wiring somewhere.

 

hmmm i have a o2 light on and the traction control code 36, but i dont have traction control.... but would u think the 02 will cause the vtec cut off? hmm i'll go threw my wires today and reconnect them and see were that goes

 

question for you guys if my motor is a 93 sohuld i be useing syn 10w30? or 5w30?
