92 LX 5.0
When i start my car in the morning and let it warm up for like 2 minutes. I take off and it feels POWERFULL, spins, MOVES.
But when it warms up it doesnt feel that powerful.
Is my fuel pump to small?

One, your tires are cold, and two, it runs richer when cold. Mine does the same thing.

damm that problem must suck. spin in the morning, spin in the evening, spin in the summer time, spin in the winter time. ride ride my 5.0 lol

i would have to say untill the car warms up its not as strong as its warm. thats the notch tho

i have the same goddamn prob..... i rode around in my car and raced a few civics that had exhaust .... i beat them by a crap load of car lengths ... then i go to race an all stock civic and only beat it by about 4 cars.... i hate it when my car warms up its so slow.... what can i do about this?

pour liquid nitrogen on it.







no, dont do that, but you could try a lower temp thermostat.
or add 9 electric fans under the hood.

lol ok i have to figure out a way to rephrase my question lol

your pump is ok for now, a stock pump and injectors is able to support about 300 hp actually. but it's also 15 years old so i would look to swap it out soon.

how is everything else? timing, fp, ? any other drivability probs? other than noticible power loss?

just from heating up, it can feel like a 20 hp power loss. when the intake gets hot, your sucking heated air rather than cold dense air, it would be similar to running ram air, then removing it. (one that works though...not the 5.0 ram airs)

would a coldair setup help with that?
