hey guys, i'm a bit lost here. I recently swapped an h22a in for the tired h23 that was formerly in my car (a 94 Si). A couple of months ago the ignitor blew and i had to put on a new distributor, however im not really sure how to gauge the timing on the motor so i had to guess with distributor placement. The car is running ok and not having any major problems but it has the infamous hesitation in the 2500~3000ish area which im guessing is due to the timing being off. My problem is (after searching) I don't really know how to fix the timing on the car. I picked up a timing light but I dont know how to use it or what the specs are for an h22a that i need to look for and all that . If someone could give me a rundown for fixing the timing with a light and all that, or even just a link to a place that could explain it, I would be greatly appreciative. Thanks in advance

 

if you look down by the transmission, kind of underneath the distributor, you'll see a rubber thing that you need to remove. now you need to hook up the timing gun to the spark plug wire for cylinder #1. turn on the car and let it idle. if you point the gun towards the hole (where the rubber thing was that you removed), you will see a mark every time the gun flashes. if you cannot see the mark, or the mark is not lined up with the mark on the motor, you need to adjust the ignition timing. loosen the distributor bolts, which there are 3 of, by a 1/2 turn of a wench (DO NOT totally remove these bolts!), and you'll notice the distributor can pivot. turn the distributor until the marks line up. tighten everything back up, check the timing one more time just to be sure, and you're done!

 

hey,

i unhooked the vacuum line (that is what youre referring to right?) underneath the distributor, and aimed the gun down there but im not sure what im supposed to be seeing. is there a mark on the distributor and a mark on the motor? and if it's that easy then why not just use a flashlight? lol i guess im confused. i thought it had to be pointed toward something that rotated or somethin. anyway if anyone can specify for me that would be great. thanks!

also do i need to plug the vacuum hole?

hahahaha. ok. look where it says h22a on the block. i wanna say right next to there is a rubber plug. you might not have one so it might just be a hole. you put the timming light in there. an you look in there for the mark.

 

youll see a mark on the flywheel rotating and a pointer on the block.

a timing flashes like a strobe light everytime #1 cylinder fires. It makes the flywheel and the marks look like theyre not even moving.

 

thanks all, found what i was lookin for. the interesting thing is when i adjusted the dizzy so the mark would line up, it just made the problem worse. turning it the other way (toward the firewall...i guess that is advancing the timing?) made it a lot better. oh wells. thanks again!

 

did you have the ecu check connector connected? I know for the 97+ ludes you have to short a connector so the ECU doesnt try to mess with the timing on you as you check it.

 

is that connect on the right panel. its blue?

 

I believe so...i dunno if the 4th gens have this or not.

 

long post..sry guys...

remember that if you're using a non-advanceable timing gun, that you do NOT go by the white cross mark. you go by the lower red mark with a 15 next to it.

if you go by the white with a non-advanceable gun you're actually setting to your timing to 0 which is 15 degrees too retarded. that could explain why your setting made your car run worse.

the ecu connector is below the radio. there are 2 connectors. the one is blue that you want. i recommend taking it off the metal it's sitting on and let it dangle down near the footwell. it will come in handy more than you think. when you're not using it, just tuck it behind the plastic console.

this hestiation (which i have btw) is really pissing me off. my personal opinion for the cause of it is aftermarket intakes + timing (for most h22 owners). it seems to me, that with the addition of an aftermarket intake, the air fuel ratios are way too lean between 2-3k. with the stock intake, the resonator had a butterfly valve to control the amount of air that goes in the intake, but aftermarkets don't have that. this makes the car ingest way too much air between those rpms.

*takes breath* anyway, check that timing again!
