i've just finished my h22 swap and im not getting spark to two of my cylinders. i see spark at the cap but it dont seem to get to the plugs in cylinder 1 and 2 or its got a weak spark if it actually gets there. after 5 mins of running the car, plugs in 3rd and 4th cylinders are toasted black and plugs in 1 and 2 are wet with fuel. the car starts but idles horrible, misfires like crazy and exhaust fumes smell shit full of fuel. h22 came with internal coil, same as the 95 ex accord, so i didnt go external. im getting no cel at all. checked the wiring almost half a dozen times already. was wondering if any of the jdm h22 swaps on the board ran across this problem. i have done the usual diagnostics already ex. compression check, timing check, fuel delivery, etc.. i have searched the forums but i cannot seem to find the right answers. is there a distributor wiring trick that i missed. been trying to diagnose this sucka for a good week now. any suggestions??

 

EH my h22 had bad injectors when I first fired her up. Don't know if thats your problem?

 

Distributor cap, plug wires, & plugs. Anything 'upstream' from the distributor, should affect all 4 cylinders.

Check the terminals (in the distirbutor cap) for #1 & 2. Check the wires for resistance, & also look for arcing (in the dark). Maybe for who-knows-what reason, the plugs themselves are fuel-fouled, & nothing helps until you put NEW plugs in.

 

i got like 5 sets of plugs in my garage. i've gone through 3 sets already. same $hit happens, plugs in cylinder 3 and 4 is cooked and 1 and 2 is not. i can smell fuel on plugs from cylinder 1 and 2. i've done new wires, cap, rotor, icm, coil already. still nothing. there is spark at cap and wires. no check engine light at all. car starts up right away, but like i said- idles horrible, kinda like a v8 backfiring like crazy putting out exhuast fumes that smells like fuel. anyone know how to diagnose??? please help. thanks.

 

have you checked to see if the spark plugs are sparking? Touch the plugged in spark plug to your manifold and see if you see a nice ark.

 

bad distributer? sparkplug wires?

 

I've had plugs that looked real clean but they were fouled from flooding. I thought I had dried them out but getting new ones made everything better.

If you've already tried that, maybe you need to move on to checking compression/leakdown, or something like that?

 

i have come to conclude that i must have clogged injectors. the resistance on them are higher than normal. pressurized fuel rail spilling more on 3rd and 4th because 1 and 2 is clogged. engine knocks and pings probably because of detonation- not enough fuel. at first i thought egr valve was stuck open or closed causing fuel overflood or ect bad but they both are good. i've got a set of good injectors coming by tomorrow. i will see about what the problem is this weekend.

 

"what the problem is?"

 

how would you know if the injectors are bad? My h22 idles perfectly fine, but when accelerating low range(1000-2500rpm) it has hesitation. Above that its fine accelerating. But at any speed if you hold it constant, it has slight hesitation.
