Hi there!

Went for a pretty hard ride yesterday with my 92 civic and now it starta to misfire and some Times' its almoste like its shooting flames from the exhaust like a turbo car on rev limit. The sparkplugs were pretty black, like way to much fuel... engine setup:
b16a2
p28ecu
msd PRO cap
msd 8,5mm superconducter wire
msd coil
4-1 racing header

Belive ther is a wideband o2 sensor, 4-5 wires IF i didnt miss. Looks like some one "shift" from smalband o2 to wideband o2

hopp you guys have some ideas!

not what i can see/feel/hear. Most of the hoeses are new.

Now after a week or so, the misfire and shooting stop, works almoste like befor the misfire problem, now it just smal jacking/ missingIF you understand what i meen.

Winter has landed in sweden som have plenty of time to search and make it trackday Worthy. Sorry for the spelling😊

Its prolly ignition related prolly the coil setup like mentioned ditch it and go with a oem Distributor. Also check your mech timing in case you skipped a tooth on the timing belt.
