won't go past 3500rpm's - Honda Prelude Forum

Phuong47 · 05-27-2002, 05:57 PM

Well my mechanic and I can't seem to diagnose what the problem is. The car won't go past 3500rpm's, does anybody have a clue to what the problem may be? TIA. And it's an atuomatic H23

Peace

when did this start?
what mods you got?'
how many miles?
what else have you tried already?

happened last weekend, been in the shop since then, only mod is an intake. Oil also started leaking from the cam area at the same time this happened.

won't go past 3500 like it's hitting a rev limiter and the engine is wailing/working hard?

You have a CAi or a short ram?

Phuong47 · 05-27-2002, 06:16 PM

it'll hit 3500 and just bounce off the car will jerk while the engine is still working, it's an AEM CAI

sounds like a vacume problem, have you run cel codes yet?

I had a similar issue when I first installed my CAi and it was clogged my car would rev to 3k rpm and then die due to lack of air. were you doing anything when this problem 1st happened? Have you checked your filter?

Phuong47 · 05-27-2002, 06:24 PM

I'll let my mechanic know about what you suggested, I'll have to get back to you on it tomorrow though. Thanks eh.

what the hell never heard of that before wont past 3000 RPMs then you can't go over 70 mph rite/....

Phuong47 · 05-27-2002, 06:43 PM

not sure what 120kph's is in mph but ya once it hits that after awhile the engine shuts down. Now imagine that happening to you with a semi-truck behind you going the same speed, freaky!!!

SiR-P12eLude · 05-27-2002, 06:45 PM

that'll be some scary ****.... advice sad but dont drive it, it might get worst....

Phuong47 · 05-27-2002, 06:51 PM

Don't worry, hasn't been driven since then, it's at the garage

check the codes if none then reset your ecu by pulling out the clock raido fuse out from underneath the hood then start the car let it run for a for about 10 min then shut it down then start it again and test drive try that

It's the intake, it's not sucking in enough air. I had this problem before.

95PRELUDEVTEC · 05-28-2002, 02:38 PM

could be the distributor....

when my friends bearings in the distributor went out...it was cutting off at 4500rpm....can't go any further

Phuong47 · 05-28-2002, 02:53 PM

Well it happened a couple of days after I got the distributor. My mechanic and I are still waiting for answer from the local Honda dealership. I hope they won't be dicks and actually help us. For sure it has to be something electrical, cause sometimes whem I start the car up it shuts down with the CEL light on and the battery light too but when I start the car again the CEL comes on and that's it.

95PRELUDEVTEC · 05-28-2002, 02:56 PM

you should try another distributor to see if thats the problem

Same thing happened to me in my car, but it wasn't going past 3000 rpms. I check the engine code and found out it was just the crank shaft sensor. I changed that out, and now it works just fine
