Hi, i've just made my dad a profile and I'm posting this for my him so after this it will be him who is replying
.
I'm going to word this post as if its him
I've been suffering from a cough at above 3000rpm. i can accelerate hard from low rpm but once it gets over 3k it coughs. if i keep trying to accelerate it dies and will cut out. If i slightly let off and just tickle the throttle it recovers.
If i leave it to die when restarted it will be in limp mode and won't go back to normal until i clear the codes. it also brings up the pgm-fi light whille in limp mode.
The codes that are coming up are
P1065 - manufacturer powertrain non specific
P0087 - Fuel rail pressure too low
The car drivers perfectly fine apart from the cough under load.
I've read many threads about the fuel filters and pressure relief valve.
I replace the filter with a genuine honda unit and also gave it a full service including cleaning the strainer in the fuel tank as it had a little bit of crap around it.
I don't know if it could be the pressure relief valve as i suffer from no starting issues and also it can start back up again straight away while warm.
The car has had a bad batch of fuel a few months back and i also found some water in the bottom of the fuel filter when i replaced it.
i think there was a very slight cough before the bad batch of fuel but it has definitely got worse since (my dad cant really remember 100%)
I've also had the car remapped which has made it very noticeably worse.
I've instructed my dad on his next tank to fill with v-power and also use redex to try and clear the system. the next things im thinking is the pressure sensor itself and then maybe the pressure relief valve.
Hoping its not the fuel pump!
Cheers for taking the time to read this.
Has anybody got any advice for my dad?
He has been a mechanic for 30 years but isn't the best on computers so please bear with him
.
Thanks again
