i am a noob on this site, but i also belong to other sites.. I have a 97 acura 2.2cl with the f22b1 engine. I recently had a miss going on and it got pretty bad. took it to my dads shop and a mechanic looked it over and found out that i had a injector o-ring leaking. replace it and the car ran great for 30 min. After that, the miss came back. there is no vacum leak, injectors are good, brand new distributer, cap, rotor button, plugs and wires. N e body have any suggestions?

 

Can the missfire be narrowed down to one cylinder? Is it a dead miss?

 

If it came and went by disturbing an injector, Logic (apologies to Mr Spock) would whisper in my ear, "possibly injector related"
Try running some Injector Cleaner thru it, and check all 4 injector connections. As was alluded to else-ware, check any vacume hoses in the vicinity.
I doubt one took a sabbatical, they're pretty much bullet-proof, so we're going to have to start looking else-ware .

make sure all injectors are clicking when car running ,,i agree with P- u might have a faulty injector ,,,,or wiring to it ,,,,,do u have a noid lite?? stetescope? have the shop do it if not............and by the way a leaky injector o-ring will not cause a miss .,,,do a compression test as well...........
