What do i do now?
ok, im stumped.
the car is an 89 crx si
d15bs, z6 head, y8manifold
boomslang obd1 conversion harness
bosch 4 wire 02
either p28 or p08 ecu. i have both availible
alright. heres whats going down.
the car has never run well in all the 50 some odd miles ive driven it. have only managed 30 of it with the boomslag harness, 2 on the p08 ecu
weve had a bunch of check engine lights. water temp sensor (good replacement, ohmed out within spec according to both 89,91 crx factory service manual, and the 92-95 civic manual)
then TPS sensor. replaced with blox piece, set to .046 at idle, and 4.38 at WOT
02 sensor. on number 5 from the parts store. tests good according to the 92-95 civic manual.
MAP sensor. tested good according to all three factory service manuals, but i replaced it with another one that also tested good.
heres whats going on now. the damn thing quit running completely. it has completely flooded itself out. the only code currently involved is an o2 snsor code. i have tried wiring it every which way, but can never get the light to go off. it also does not turn off the light. we have checked continuity and resistance of all wires between the sensors and the plugs into the ECU on the boomslang harness. all wires go to the correct pins acording to the manuals. we have tried the two different ecu's. we have cleaned, rechecked,etc all connections. we have changed the fuel filter. we have run all the diagnostics we can according to the factory service manual. every sensor checks good. it will crank at wide open throttle, but floods itself out in short order. what we did find was that the screw had come out of teh rotor, causing the timing to go wonky. that was fixed, but we are still having problems. i am at the end of the factory flow charts, the end of all my wild guesses, and the end of my rope. i dont have money to throw at this thing in wild guesses with parts. i really just dont have a clue. i even had a tech from the local honda dealer come and recheck me. no dice. weve even flezed and jiggled all the wires and connections looking for internally intermittantly broken wires. havent found a ting.
to sum it up, the thing doesnt run anymore, and all the diagnostics that the manual has has come up fine. no problems other than the 02 code, which shouldnt make it puddle gas in the cylender like it is doing.
running extremely rich.
will only run briefly at wide open throttle, never revving past 2000 rpm, and then kills itself off.
so, what the hell do i do now??
