Ok hello all, im new to the site!
I have code p1259, i know what the code says(vtec system malfuntion). I recently have had the cars motor rebuilt at 190k miles. Practically new everything has gone under the hood. New oil pump, water pump, all belts, new vtec vlave assembly(including sensor), new knock sensor, new oil pressure sensor(located behind motor), new coolant temp sensor/switch(both), new pistons/rings (cylinders have been bored to .020 over? {20 over}, new front rear seals, new tie rods, ball joints, upper/lower control arms, shocks, new 8lb flywheel, stage 1 clutchmasters clutch, new transmission seals(ones for the driveshafts), new rear balance shaft, head has been polished/reworked while motor was being rebuilt.
Problem, can not get code to stay away when i reach over 4k rpms. I had the problem in 1st gear once i hit 4k rpm. I checked oil and it was fine but i added enough to hit the max fill line. Problem has now moved to 2nd gear at 4k prm. That does not make sense to me but at least you have the facts. Yes motor was primed before we started it for the first time. And ive already replaced all the parts that normally cause the p1259 to trigger in the first place. Only thing i have not done is take valve cover off, loosen all the head bolts and re-tighten. The mechanic has said he torqued them to correct specs at 22lbs then 90, 90, 90 degrees. Just like honda states for new head bolts. Could running recommended 5w20 in this motor after its been bored cause oil pressure to significantly drop? And to the best of my knowledge the oil pump works cause i have oil on top of the camshaft/valves or whatever the other parts are under the valve cover. Please help, cause this is my daily driver and have been without it for over 5 months. Plus my wife is going back to work in 3 weeks from having our first child. And car must be running. (i have spent over 4k in this motor and can not spend much more) I need good help from people who have experience this or have an idea of what could be wrong. I will be checking forums about 12-18 hours from now since i will be working, so i wont be able to quickly respond to any answers/questions. F23a1 is my motor year is 2000 LX 5spd. Im just tired, and can barely find it in me to continue without help. PS(took it to honda they were no help) told me what the code was and what to replace and said it might not fix the problem. And it didnt.
