Engine problem dont think its the hesitation problem - Honda Prelude Forum

jgcpn33 · 05-01-2003, 03:47 PM

Just started happening today, and seems really bad now.........
Similar to the notorious jdm h22 hesitation problem, its bogging down and hesitating badly.....feels like its getting worse..... it starts around 3000 rpms and barely gets better as the rpms go up.....
between 3 and 4k rpms it feels like its sputtering back and fourth......
I had the jdm hesitation problem for a long time and finally got it fixed a couple months ago by replacing my injectors..........
I'm waiting for my car to cool down because i replaced the plugs with ngk coppers last week and i'll make sure they look alright.............
but this is feeling really bad........
Anybody got any ideas????
I've replaced my whole distributor recently and my injectors as i said so its not those......
I have no clue if this could be it, but my throttle has seemed kind of funny recently, maybe kind of loose, but after I replaced my plugs, everything was great and ran awesome so i dont know???

This is making me mad though cause ever since i got my car its been problem after problem!!!

Thanks in advance
Jonathan

How are your plug wires?

wires should be no more then 500ohms per foot.

G_Loc · 05-01-2003, 05:05 PM

spark plug wires should not measure more than 25k ohms.

jgcpn33 · 05-01-2003, 05:18 PM

well i just took a quick ride to see if i could be more specific about the problem and D*MN!!! it is bad.....it takes me forever to get up to 40mph ....i just sit there......like i said it sputters between 3-4k rpms and after that its just bogging the rest of the way.....its horrible even when it gets up to vtec....
after i turn my car off theres a loud ticking sound coming from the exhaust i think....is that normal?
I know this is probably not it at all but could it possibly be an exhaust leak or something??(lol that would just be an excuse to borrow money from my parents for and exhaust system without having to wait to save up

So what kind of tester do i get to test how many ohms are running through the wires?

blueludeWV · 05-01-2003, 07:35 PM

I'm not real sure how to check the wires. I would just replace them if they have many miles on them.

Also, you might try running some Dry Gas through the tank. It kinda sounds like bad gas. Its really cheap and 2 bottles wouldn't hurt.

This sounds like my problem too. Accelerating from the light is horrible sometimes. Feels like I have the pedal pressed in about 5%. And sometimes I can nail the gas at some rpms and the exhaust note changes but the car does not accelerate.

jgcpn33 · 05-01-2003, 09:49 PM

yeah thats exactly how mine feels.......i noticed the engine sounds like its roaring and i go nowhere

jgcpn33 · 05-01-2003, 09:51 PM

4bidden: what all have you tried doing??
it couldnt be an exhaust leak or something could it??
i also noticed alot of shaking starting up from a stop

Tola · 05-01-2003, 11:58 PM

I've had this exact problem about 2 years ago. When the engine is warm, it would hesitate, bogg, sputter, what ever you wanna call it, across the whole rpm band. It takes me forever to get up to speed, even when in VTEC. I've tried replacing all the simple parts (plugs, wires, O2 sensors, filters, PCV valve, valve adjustment, etc..) Nothing really helped. So I decided to fool around with my timing. I advanced my distributor timing, problem fixed. So check that before anything else.

How long does the ticking from the exhaust last? And is it comming directly from the muffler or closer to the engine? It's normal for the engine to have a few ticks for a few secods after you shut the car.

jgcpn33 · 05-02-2003, 12:23 AM

it tickes for a couple minutes but i've never timed it and have gone inside before it stopped so i dont know how long, and it was coming from the exhaust closer to the engine than muffler........
the distributor timing could be it considering when i replaced my distributor i never timed it...
I forget which way i ended up turning it towards but I just went by sound and i think i put it all the way to the back.....
Are all timing guns gonna run from $40 and up?

What kind of fuel pressure you running?

After I installed my OEM fogs yesterday I did a valve adjustment and bumped the fuel pressure up to 40-41 at idle and the car felt really well tonight. VTEC xover sounded like it used to and no noticable lag accelerating from a light.

Question for you though.....

Do you have a Greddy header?
Do you have an exhaust leak?
What octane are you running?

jgcpn33 · 05-02-2003, 08:17 AM

I'm running on stock fuel pressure.....I have a b&m fpr, but i'm waiting till i get a guage first before i install it....
i'm still on the stock exhaust system.....and i'm questioning that i might have an exhaust leak but i dont know how to find out.......
I have dc sports cc headers(i know i know, everyone says they're crap)
i'm gonna install them when i get my exhaust system(thermal stealth)
I'm running on 93 octane...

So you think the valve adjustment and bumping the fuel pressure solved the problem?
Cause i have noticed quite a bit of valve ticking lately.....
I dont know how to adjust the valves but i might try by following a write up or take it to honda......

4bidden · 05-02-2003, 12:14 PM

I used to not have a fpr or a gauge until I made my ex buy me them for a recent holiday, forget which one. Anyways....I installed the gauge before installing the fpr to see what it was set it, I was VERY surprised to see 32psi. That was with stock regulator and the b&m gauge. I then installed the fpr and bumped it up to 38psi and have been driving on that for a while. Then like I said, the other night I just decided to bump it up some more. So it is now at 40-41psi at idle, forget what it was for WOT. I am running 91 octane premium, so the difference in octane might be the reason why I have to dump so much more fuel to keep it running well. Dont know, I might call the dyno shop shortly to get an appt for early next week. I'll definately let you know if I find anything out. In the meantime I'm going to call Greddy and tell their sorry a55e5 to send me gaskets for my header and my damn exhaust!

jgcpn33 · 05-02-2003, 01:08 PM

whered you get your guage ...i need a cheap one
thanks for the info by the way

4bidden · 05-02-2003, 01:17 PM

I got the gauge and fpr from lightningmotorsports. They do a deal for HT members for both for pretty cheap.

jgcpn33 · 05-02-2003, 01:24 PM

well i already have the fpr but summit sells the gauge for 30 and i'm about to buy it but it says its for
"Acura: 1990-99 Integra; Honda: 1988-91 CRX, 1988-99 Civic"
But thats what all the sites say the b&m guage is for.......
I'm pretty sure they're universal guages but i just want to make sure.......????

4bidden · 05-02-2003, 01:30 PM

Yea, it will work.
