my question is when im pressing the gas pedal the rpm was slowly goin up..
even if its full throttle, still slow.. i tried the timing but still.. cant figure it out.. the car pulling strong like couple of days ago b4 i broke the dizzy n i replace it already.. can anyone help me pls.. thanks..

 

It's probably because it's a d-series Seriously what motor and which car?

I have the same problem 4 door D Series engine....I wonder why

 

I have a 93 eg hatch with itr 96 spec.. When its cold it runs strong.. But when its like warm enough it starts lagging... when I press the gas pedal the reaction of the throttle was late..

 

man, they need to make a huge sticky of most possible solutions of these problem. seriously, there are hundreds of things that could cause this. More details the better.

 

Any CEL?

 

sorry..still a noob.. what's CEL?

 

check engine light

 

Oh ic.. I have obd2 conversion n I'm using p73 obd2 ecu.. There's no CEL..

 

yea man, good luck, might as well start replacing everything from your fuel pump, down to your ground wires

 

I had same problem on my bro's 00 hatch with b18c5... One of his fuel injector wiries un pluged, that made it a 3 cylender. It still made power but slower.

 

how did it sound tho?

rofl +1!

 

im gona try 2 change my plugs & plug wires..
btw it sounds like its just getting air but doesnt pick up any speed..

 

how does your car idle? and does the engine have slow accel or the whole car its self?

 

nope.. it doesnt do idle or maybe it is but not rough.. its just the engine..

 

maybe the tps is starting to go out???

 

when the engine is cold it runs strong...therefore when it goes into closed loop the problem starts. try pulling the "back up" fuse for like 15 seconds. (under hood fuse) should reset your ecu. kinda sounds like the ign timing is off

 

same happens to me now... My reason though is because I took off my IACV and cleaned it out.. and attemting to remove the gasket that looks like an 8, I realized it was dry rotted because when I tried pulling it, pieces of it just started falling off. I now have a small vacuum leak. It's really only affected when the car warms up. When it's cold, the engine pulls NICE but once it's warm.... DAMN IT SUCKS.. Ordered one from HONDA last week.. Week and a half I have to wait for a stupid 2 dollar TINYYYYY gasket/seal. It will be here in 2 days. Did you mess with the intake at all? Timing maybe too... but I don't think it would affect with different temps.

 

I had that problem once with an older accord, found out one of my plug wires had melted and grounded out...... doubt thats your problem though but hey was a shot in the dark.

 

its possible, however a vac leak, is only dominant at lower speeds/rpms/engine loads, so @ wot, it shouldnt be as noticeable. Its gotta be fuel, I had my issue fixed, then it came back (swapped the fuel pump)

now im pretty much clueless since its been 2 years with this problem, it might be something internal.
