Ive been making progress with my car almost everyday its been running better. ive finally got it running pretty decent. on a cold start it idles a lil rough and if you dont give it a lil gas two or three times it dies out, im going to check out the condition of the IACV and most likely clean it. Ive done just about every maintenance thing you could think of timing belt, water pump tensioner cap, rotor, plus,wires, thermo, fuel filter, one 02 sensor is new (bosch) one is a known working one.

setup is 90 crx si b16a OBD0 pr3 , rywire vtec harness, crx engine harness with 02 sensors wired correctly(secondary going to fact harnes, primary going to rywir)... let clutch out bogs a lil from like 2k-2.5k then goes ok doesnt really pull hard, hits vtec, but not very loud like my gsr did, then pulls ok (not hard), till 7k, when all of a sudden it just rips . pretty much it feels like its bogging through out rpm range till v7k.

i get a cel light for o2 sensor 1 most of the time sometimes both mostly when loading the engine, i have the factory crx exhaust on still and who knows how old the cat is, but i dont think any of that would produce a bogging problem.... one of the only things i can think of is maybe the fuel pump, most likely original with 180k on it, but if it were dieng i wouldnt think it would bog down low and rip up top,

timing is spot on, cam timing marks are good , (checked 3 times) adjusted valve lash, did top end cleaner, i cant really think of too many more things that could possibly be doing this, pcv valve is old, but i dont really think that would affect that, i will replace soon though... can some of you gurus point me in the right direction.... havent been getting much help with my trivial problems... maybe cause im a nnoob on here but i think i hae a genuine tough problem now, ive done a few different swaps before so i have a good knowledge of wrenchin , but please help!!!

 

also i noticed when the cel comes on it runs better, and pulls harder down low, but it obviously wont rev as hish in limp mode... some im thinking maybe whatever limp ode does to your engine i need to do too... some one help
