hey guys my b18b is getting worse since i did the swap. first of all idle sucks. it jumps up and down and stalls sometimes i cleaned the IACV and FITV. im going to screw with the FITV some more and hope i can get it fixed if not im stuck there. and secondly the car stutters really badly at low rpms when i mash the throttle, and sometimes it will even lag and do nothing when i push on it at low speeds then it will kick in and the car will jerk forward like i just launched the thing. i know its ignition but i checked my plugs and they are good, dizzy dosen't look bad either but im going to replace the cap rotor and plugs tomorrow, what brand should i stick with/stay away from. the car is just also getting really shitty gas mileage as well, about 200-250 miles per tank. Im thinking of just getting a full tune up done at a shop but i dunno how much that goes for plus i'd rather do it myself im just getting a little sick of working on the car right now. any help would be appreciated. thanks

 

bump i need help please!!

 

Check the gapping in your plugs. What injectors to you have?

Check your fuel filter. Changing your spark plugs and making sure they're gapped correctly could certainly help.

Have you looked at the Throttle body? Make sure it's clean. If you have a timing light it wouldn't hurt to check your timing either.

 

already did the timing, do you think it could be that im using two of the injectors from my d15? i was told that most honda injectors are all the same 240cc but unfortunately i dropped one of the b18 ones so the plastic on the bottom is cracked, im sure i could still use it maybe i will swap in the original ones and see what happens, i will make sure the plugs are gapped correctly, im going to replace the fuel filter prob tomorrow cuase i know it has never been changed since i owned the vehicle but it is the same one that was in when i had the D series and that motor was fine. TB Looks clean but i haven't taken it off or anything to be sure.

 

sounds like your engine is starved by using those d15 injectors. Depending on the injectors it's likely not enough fuel.

Get some ls injectors.

 

it does run fine at WOT but yea i guess i will replace that broken one and get a new seal kit and see what happens. I am planning to boost so if i got some DSM injectors right now and plugged them in with no tune would they work?

 

With a stock motor dsm injectors will likely make your car run rich. (provided you're talking about turbo DSM injectors. (which are likely between 400-550 cc)

 

if the "broken" injector has only the little cap broken, you can still use it. i believe it's called a pintle cap, and it's just to protect the little needle on the injector. look closely at the broken one and see if the metal bits are broken. if they look exactly like the non-broken injectors, pull off the cracked pintle cap and you can run the injector just fine.

 

yea thats all it is is the plastic piece thanks for that advice that helps a lot, the rest of the injector is fine, no metal broken.
