i have an NA b20vtec with hondata s300. after it was tuned by my tuner,it was running good. but a week later i had to take the engine out of the bay to fix some leak at the water pump and replace oil seal. then i installed everything back. but since then ,when i ran the car,i couldnt rev it pass 2000rpm. the car just bogged. i check the ecu,it was ok. i used other distributor just to check whether its faulty,same thing happened. i check the grounding,still the same thing happened. so i dont know whats next.
the only thing that i made on the engine after the tune was,replacing the tps sensor,which shouldnt make a different since it was tuned in map mode, i didnt check the ignition timing coz i put it back to the mark i made before dissambling it. and i set the cam to given spec.same spec as before.
so anyone?

 

sounds like my 92 when the cat pluged up.

start the car and run it at a hard throttle. then after like a min or two look under car and see if the cat is red. if it is it's pluged and it needs to be fixed be for you burn your valves

i checked the dizzy already,its not the dizzy. i havent had time the past few days to check on the prob but a fren suggested that i cex the voltage when i rev it to see if the alternator is charging it.

 

Did you put everything back the way it should when you did the oil seal? If not, your timing could be off. If it's not that, i would check your fuel pressure.

 

i did put the cam timing back to spec. except the ign timing which i only lined up with the mark i made b4 dissambled it.i cex the fuel pressure and even changed to diff FPR. stil prob

 

same problem here d15b
