i have a problem with my fresh ls/vtec i was breaking the enngine parts for like 2 months now n i have a issue the car wont idle correctly it dies if u give it gas it will bogg n die but if u tap the gas pedal it wil go to 6k rpm no cel codes

keep in mind car ran like a champ before idk wtf wrong with it now
it started doin when i was driving to school it was bogging out but i turned the car off n on n it ran good again for maybe 15 min but after couple tries even turning it off didnt help had to get it towed home

i changed
injectors
ecu
3 working throttle body
spark plugs
spark plug wires
calibrate the tps
idle control valve
timing is correct
no noises in the engine
compressions good 150 all across

plz help me out

 

That is NOT good for a newly rebuilt engine the minimum for the b series is something like 180 anything lower is considred bad heck my d16y7 has more comp than that. you should be pushing 250-260. unless you mean something else by "breaking"

 

i got low comp pistons getting it ready for turbo

 

well that still may explain the bogging/feeling slow 150 comp for a N/A engine is weak I know the whole lower comp for boost but in the mean time it will feel slow

 

n now whn u try cranking it over wont even start soulds like itll b pushing the air into the intake mani shoots out flames from there

 

but it ran like a charm for 2 months didnt beat on it or nothin 3-4k rpms sometimes went over 6k once

 

is your mechanical timing on ?

 

timing is good timing gears r set up correctly n the shaft

 

all right ii got the problem solved

what happend is My Fuel Pump Fell Off Te Bracket N Fell In The Gas Tank N It Didnt Get The Right Amount Of Fuel but the car still ran fine

if someone has the issue and i knw some of u do cuz i spent couple days reasearching n no one seem to get the problem fixed check ur fuel pumps !!!!!!
