i have this car and everytings good except it feels lazy. i have changed timing belt, water pump, spark plugs, checked the tps, replaced the map, changed the fpr, switched ecus and tried all kinda other stuff and nothing seems to correct the problem. the ignition timing is on point, the timing belt it set right. i have no cels and other than that the car is good. also the compression is good at 210 210 210 210. it mostly is sluggish on take off rpms between 1k and 3k then you feel it pick up like a burst of power comes in. i let some one drive it to feel it out and they even said it feels like vtec is not comming in but you can hear the crossover when you hit 5500 rpm and a slight increase in power. but in my experience in having a previous b16 in an eg with gsr cams (this engine also has gsr cams) the car would pull alot harder and have more power and no hesitation. the only thing i have not replaced is the distributor and iacv but the car idles fine and a distributor either works or dosnt work right? again i have no check engine lights. please help

Replace the plug wires, distributor cap, and rotor.

check o2 sensors!!

blackcrx16

all o2's have been replaced.

blackcrx16

actually the o2's been replaced twice under warranty just so i could be sure it wasnt them

blackcrx16

i have replaced the wires,cap,rotor,plugs(twice),o2 sensors, map sensor, fuel pressure regulator, tested the tps, pcv valve, swapped the ecu, timing belt, water pump, oil seals. i have changed all this stuff and still nothing and the car is not loosing coolant and it has compression so i duno anymore

Measure the fuel pressure with and without the FPR vacuum hose connected.

i am in the process of replacing the fuel pump with a walbro 255 and replacing the fuel filter. ill let yous know what happs

blackcrx16

these didnt make a difference. i had already replaced the fuel pressure regulator. would the distributor cause this kind of problem with out showing a check engine light? like if something was going bad but not bad yet?

i have ngk iridium plugs in, i had them in before the problem and when it started i put new ones in again and same thing.

Jimster480

It just recently started feeling like this? Or does it feel like this after a swap? because you have replaced like everything already so...

blackpearlgsr29

id try sum ngk standards they perfom the best and factory calls for them

Jimster480

he said he already tried that
and its V-Power. No NGK plugs are gonna make it run worse.

joelmatt89

it would be helpful to know when this problem started. Have you notice a difference in your mpg

sounds like a dizzy issue to me

blackcrx16

car was running fine for almost 8months after the swap, just recently in the last 2 months now ive been noticing it.

blackcrx16

just started recently, mpg i got 28 highway and about 24.5 city

blackcrx16

just swapped a dizzy from a friends known good one and at first it ran fine but the car had cooled down but after about 10 min driving around it came back. it seems like the car drives fine when its cold or cooled down but when you drive around and the car warms up it starts to hesitate and not accelerate smooth and when its hot out side you really notice it even more. like if you move off from a red light it bogs down and has no power and then when it gets to around 3 rpm it gets a burst of power and accelrates better but does not accelerate smooth through out the rpm range. you feel very light jerks.

is the car overheating? If the ECU thinks the car is overheating it will like retard the timing, etc to keep you from blowing the motor. This happened on my car when i first got it, it was overheating and i didnt notice it the first couple of days i was driving it.

blackcrx16

i dont think my car is over heating. the needle is slightly below half, and it dosnt feel hotter than usuall and the radiator fan cycles on and off like its suppose to.

blackpearlgsr29

they got standards u juss gota ask for STANDARD and v-powers foul out quik. if ur cars runin lean and u get hotter plugs it will make it run worste and hesitate no matter the brand but im a certified Honda tech juss givin my input good luck with ya ride

Jimster480

how do V powers foul out quick?
