well, this is the third time i uninstalled my JRSC, but, now this time, ive put all the stock parts on and experienced a problem. i am getting some serious bogging acompanied by a cylinder misfire #2 code. heres the facts: 99 civic si b16a2.
new copper plugs gapped at .050. oem wires are 6 months old. cap, coil, rotor are about 8 months old. valve adjustment 8 months ago.

there are no vacuum leaks. i however, i am not sure if correctly rerouted the vac lines the way they are supposed to be. im pretty sure i did, but, i will find a diagram for it somewhere to compare and make sure. i also had to T into the brake booster line provide vac for the cruise control. map sensor vac line goes into the back of the mani.

MAP sensor has been "T"ed into a 3 bar map sensor junction plug. obd2 injectors have been "T"ed into OBD1 injector clips. I had to ghetto rig my IAT sensor connection because, i lost the original junction plug when i had the hondata on. does polarity matter with the IAT sensor wiring?

i plan on picking up a compression guage and timing gun from my buddies house tommorrow. i will also check plug colors tommorrow and swap em around to see any changes. i would have done all this tonight, but, im kinda exhausted from my non stop effort of changing out the clutch and putting my jrsc b16 back to stock. ill tackle this again tommorrow. i would appreciate any info or help until then.

what causes a misfire?

check the wiring on the injectors....


why the .050 gap? i thought you should be running like a .032 gap?

spidermancivic

i believe the recomended gap is from .043-.057. dont qoute me on it though. ill double check.

#2 spark plug visually looks like it hasnt even fired (looks brand spanking new). the plug is recieving spark. gonna check the injectors next.

boostedeghatch

yeah.. check that gap , i think its smaller

spidermancivic

the gap is good. the recommended gap range for the usdm b16a2 is between .047 - .055.

rechecking over the injector wiring and soldering, it is very good and clean. im thinking its the injector itself.

boostedeghatch

where do you get the specs on the gap range when using the JRSC?

spidermancivic

the specs are for the stock setup. NOT with the JRSC. reread the first post. the car DOES NOT have the JRSC on it. it has the stock manifold.

anyways. all injectors check out fine on the 9v test. they are clickin and kickin. gonna recheck more wiring. after that im pulling out the rail to see if it sprays.

i first rewired the injectors, now i know for sure there is a solid connection. still was doing the same thing.
now i swapped the (a) #2 injector into #4 cylinder(b) and #4 injector into the #2 cylinder. basically i swapped 2 and 4 around. now that#2 injector that is in #4 cylinder is flooded with fuel.

im assuming i need to find a good set of working obd2 injectors. now, how the hell do i get the fuel out?

boostedeghatch

just get another obd2 injector, put it in, start the car up... fuel would burn itself out i would think

I had misfire issues on my jrsc'd civic after I did the tps mod. Did you ever mess with your tps wiring at all? I would get misfire codes but never get any tps codes. I would always trace the problem back to my shoddy tps mod wiring.

spidermancivic

swapped out all injectors with known good ones. #4 cylinder is flooding. all injector wires resoldered single. tps and map tested out good. i am really lost and pissed.
