Hi

I have a stock 2001 SE 70000 km and slow performance problem.
When I press the gas pedal too quickly the car "jerks" while trying to accelerate in 3rd and 4th speed at about 3500 to 4500 rpm. Also, the VTECH is not always engaged at about 5300 rpm but sometimes 6000 rpm or not engaging at all. Also, it has a poor intermittent performance problem which makes the car feels more like a civic than a prelude. I previously had 5 Honda car in a row and was statisfied with the 4 previous ones but I am thinking of getting rid of this problematic Prelude. The Honda dealer can not find the problem with it. The average oil consumption gives 1.2L average for 1500 km. The sprak plugs, rotor and cap distributor (not the cabling though) were changed and it improved a bit the perfromance but the slow performance problem is still there.

What should I do?

Thanks

Fab

 

its an auto prelude, its not a twin turbo supra. the downsides of an auto tranny..plus the lude isnt the fastest car either so dont expect it to make u feel fast, since it doesnt have the greatest amount of torque either

 

it's a manual 5 speeds. But sometimes it is has really good performance. I have already easlily beaten a BMW 323. What I mean is that sometimes it responds quickly but sometimes the motor does not respond or slow to respond.

 

Variable Valve Timing and Lift Electonic Control
Wtf does the H stand for? ...VTEC. I know youve looked at the valve cover so how can you get the spelling wrong?

About your problem, try running some seafoam through it and also the gas tank, worked wonders on my h22.

 

Im sorry but some of these hillbillies should be driving a mustang. VTEC

 

my bad bro...it could be the weather. when its hotter you see poorer or more humid you'll see a sluggish car, but when its nice and cold outside the car will feel the best it could

 

change the ignition wires and the fuel filter

fuel filter isnt neccessary its almost a brand new car

 

sounds like a case of the dredded h22 lag. Make sure your throttle cable isnt sticking. Also check your timing even though its a new car. Mine does it once and a long while. Also, let the car come to full temp before you go mashing around on the throttle Check your oil level, make sure you are getting sufficient spark/fuel. Basically a tune up. check it out, try to narrow it down if at all possible.

 

yup mine does too sometimes.....under 3500 rpm it seems to be a bit sluggish, just a bit. Just think of it like when you got the AC on but half of that sluggishness.

I test drove three 5th gen preludes aleady and they all feel sluggish down low like mine. I just thought it was supposed to be like that. **** I use to have a 93 lude and seems a lot stronger in the low rpm.

Hey i'm gonna try to get new spark plugs, wires, and cap and try some injector cleaner and I'll tell you if it makes a difference.

 

if you had a 4th gen si...then that thing has more torque than our vtec models do

 

So I noticed but it is surely not normal !?

What can I do to fix that problem?

Also, the jerking problem at fast acceleration is present at any weather.

It rings a bell. I noticed that during colder weather the rpm was oscillation between 1000 and 2000 rpm at idle at start-up and then it stopped. I have told that to Honda dealer and they almost laughed at me. At this time of year it does not oscillate. Is it a throttle cable problem?

Thanks

 

you sure the h23 has more tourque than a h22a4? I think the h22a4 has 161 ft lb or maybe 156 ft lb. I didn't know the h23 was that high?

 

yeah the h23 has 160hp and 156ft/lb of torque. its the same for the h22 torque wise, but i drove both cars and to me, it feels like the h23 has more pull at lower rpms. me and my friend both have the same mods also, but his car always pulls on me from the start and i pull on him later

 

I forgot to say that the cut-off protection is not activated past 7400 rpm.
I went to 7800 rpm 2 or 3 times and the motor was still revolutioning. Is that normal?

the torque peak is lower in the rpm range...its not all about peak torque numbers...its about the curve

if you based that on the stock tach its off. so yes it is normal since at 7800 indicated its usually doing more like 7300rpm.

 

 

Based on my oil consumption test results, Honda Canada suggested 2 options for my car:
1) Have the motor block opened to be inspected by Honda dealer and change parts as necessary.
2) Run additional 1300 km oil consumption test with 10W30 oil and then perform option #1 above.

I will call again tomorrow to see what could be the benefit of option #2 if any.

Honda Canada say that they do not change the motor block following an oil consumption test revealing excessive oil burned (over the authorized limit) unless it would cost more replacing the internal motor parts after evaluation.

I would like to give a response tomorrow because this exercice has run for 4 months now and I am fu.. with it. What do you suggest?

Thanks

 

thats all in your head, my h22 makes more torque than an h23 ive had both motors, my car put down 160something at the wheels..at only 4700 rpms.....thats kinda like an urban legend

 

I had the fuel filter changed but it had no effect nor improvement on my lude bogging (jerking).
After some different Honda dealers and even different technicians at Honda dealer I now got some news. Today I had Honda tech to go with me for a trial to have him experienced my lude "bogging". After a while he admitted that there was something wrong with my car. I left my car for the day at Honda dealer and finally the problem is a KNOWN one for Honda since there is a Honda service bulletin about it!
The problem is that one of the belts (timing belt an 2 idler belts) is not properly seated anymore on the pulley and is hitting the engine cover and make particules that obstruct a sensor. The work to be done is to change the timing belt and the 2 idler belts. Honda dealer says that it is under warranty (less than 100 000 km / 5 years) and will change all 3 belts for free. They are ordering the parts and I will keep you posted if that really fix the problem. I recommend that you peoples have that verified before the warranty expires.
I wonder if once the belts are replaced what will prevent the problem to occur again?

 

what it is all about the peak numbers.... i have seen lots of 5th gens and 4th gen vtec dynos and the h22 seems to pull better numbers in the 4th gen models I do not know if it is all the extra stuff the 5th gens come with or not but the peak numbers seem to be be about 10 - 15 whp higher than the 5th gen cars do not know why that is but it is..
